You are driving on a two-lane roadway and intend to overtake a delivery vehicle ahead of you. You notice a road intersection marked 75 feet ahead. What is the legally required action in this situation?

Remain behind the vehicle until you have safely passed through the intersection.

Accelerate rapidly to complete the passing maneuver before reaching the intersection line.

Exceed the posted speed limit temporarily to clear the vehicle before the 100-foot mark.

Initiate the pass immediately if the roadway has a solid yellow centerline on your side.

Show answer & explanation

Answer: Remain behind the vehicle until you have safely passed through the intersection.

Answer

The driver must remain behind the vehicle until completely passing through the intersection, as passing within 100 feet of an intersection is strictly prohibited.

State driving traffic laws strictly forbid drivers from driving on the left side of the roadway to pass another vehicle within 100 feet of an intersection, railroad crossing, bridge, or tunnel. The safest and legally required choice is to hold position behind the vehicle until clear of the intersection.

Step-by-Step Solution

Identify the distance to the upcoming intersection.

The intersection is 75 feet ahead, which falls within the 100-foot restricted passing boundary.

Traffic safety regulations prohibit driving on the left side of the roadway when approaching within 100 feet of an intersection, railroad crossing, bridge, or tunnel.

Determine the legal driver maneuver.

Maintain position behind the lead vehicle until clearing the intersection completely.

Executing a pass near an intersection creates severe collision hazards with turning vehicles or crossing traffic.

Question 2222Question →

You are traveling in the center lane of a three-lane urban corridor approaching a signalized intersection with a solid green traffic light. As you approach, a large delivery van in the left lane and a public transit bus in the right lane both slow down significantly and stop short of the intersection, blocking your view of the crosswalk and side streets. Which of the following is the safest defensive driving action to take?

Maintain your speed and proceed through the intersection since your lane has a solid green light and the right-of-way.

Reduce speed, cover the brake pedal, and prepare to stop before entering the intersection to verify that no hidden pedestrians or emergency vehicles are crossing.

Accelerate past the stopped vehicles quickly to clear the potential bottleneck before any hazards enter your lane.

Perform a sudden full stop immediately in the live traffic lane and sound your horn continuously to alert drivers behind you.

Show answer & explanation

Answer: Reduce speed, cover the brake pedal, and prepare to stop before entering the intersection to verify that no hidden pedestrians or emergency vehicles are crossing.

Answer

The safest defensive driving action is to reduce speed, cover the brake pedal, and prepare to stop before entering the intersection to scan for hidden hazards such as crossing pedestrians or emergency vehicles.

When vehicles in adjacent lanes stop unexpectedly at a green traffic signal, defensive drivers anticipate that those drivers are yielding to a hazard not yet visible—such as a pedestrian crossing or an emergency vehicle. Easing off the gas and covering the brake prepares the driver to stop safely if the hazard enters their path.

Step-by-Step Solution

Identify the environmental visual obstruction

Recognize that adjacent stopped vehicles (the delivery van and public transit bus) completely block visual scanning of the crosswalk and intersecting cross traffic.

When surrounding vehicles stop unexpectedly at a green signal, drivers must anticipate an unobserved hazard ahead.

Adjust vehicle control and speed proactively

Ease off the accelerator and place your foot lightly over the brake pedal (covering the brake) to eliminate reaction time lag.

Covering the brake significantly decreases total stopping distance if a hazard appears from behind the visual barriers.

Scan and evaluate before proceeding

Verify that no vulnerable road users or emergency vehicles are crossing through the obscured zones before accelerating.

Defensive driving requires confirming path safety rather than relying solely on signal right-of-way.

Question 2223Question →

While traveling in the far-right lane of a multi-lane highway, a motorist observes a stationary law enforcement vehicle parked on the right shoulder with its emergency lights flashing. Heavy, bumper-to-bumper traffic in the adjacent left lane prevents the motorist from executing a lane change safely. Under standard Move-Over statutory requirements, how should the motorist proceed?

Significantly reduce speed below the posted limit and proceed with heightened caution in the current lane.

Maintain the posted speed limit while continuously sounding the vehicle horn to alert emergency personnel on the shoulder.

Come to a complete stop within the active right travel lane until traffic clears enough to change lanes.

Force an immediate lane change into the adjacent left lane, requiring neighboring drivers to yield.

Show answer & explanation

Answer: Significantly reduce speed below the posted limit and proceed with heightened caution in the current lane.

Answer

Significantly reduce speed below the posted limit and proceed with heightened caution in the current lane.

Standard Move-Over legislation establishes a two-tiered obligation: drivers must vacate the lane closest to a stationary emergency vehicle displaying active lights if safe to do so. If traffic or road conditions prevent a safe lane change, the driver must significantly reduce vehicle speed below the posted limit and pass the scene with extreme caution.

Step-by-Step Solution

Identify the situation and governing regulation.

Recognize that a stationary emergency vehicle with flashing lights on the shoulder triggers the Move-Over law.

Move-Over statutes apply to all stationary emergency vehicles displaying active warning lights.

Evaluate traffic conditions for a safe lane change.

Determine that changing lanes into the adjacent left lane is unsafe due to heavy, congested traffic.

Drivers must never execute a lane change unless there is adequate space and safety clearance.

Apply the statutory secondary requirement of the Move-Over law.

Reduce vehicle speed significantly below the posted speed limit and proceed past the emergency vehicle with caution.

When moving over by one lane is impossible, the law requires speed reduction to protect roadside workers and emergency responders.

Question 2224Question →

When a school bus is stopped on a two-lane undivided roadway with its red lights flashing and stop signal arm extended, drivers traveling in both directions must bring their vehicles to a complete stop.

True

False

Show answer & explanation

Answer: True

Answer

True

The statement is correct because traffic in both directions on an undivided street must stop when a school bus activates its red flashing lights and stop arm, as children could be crossing either lane.

Step-by-Step Solution

Identify the type of roadway and the status of the school bus.

The scenario features a two-lane undivided roadway and a school bus displaying active flashing red lights with an extended stop arm.

School bus stopping regulations depend directly on roadway configuration (divided vs. undivided).

Apply state traffic laws for school bus stops on undivided roads.

Drivers approaching from both directions must stop completely before reaching the bus and remain stopped until the red lights turn off.

Undivided roads have no physical barrier, meaning children unloading from the bus may safely cross both lanes of traffic.

Question 2225Question →

Four road users arrive at an intersection controlled by four-way stop signs. Arrange the road users in the correct order in which they must be granted the right-of-way to proceed safely through the intersection.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct order of proceeding is: First, the pedestrian stepping into the marked crosswalk; Second, Driver A (first vehicle to stop); Third, Driver B (second vehicle to stop); Fourth, Driver C (third vehicle to stop).

Safety laws state that pedestrians in marked crosswalks must always be yielded to first. Once pedestrian movement is complete, traffic order at a four-way stop is governed by arrival order: the first vehicle to come to a complete stop moves first, followed by subsequent vehicles in the exact sequence they arrived and stopped.

Step-by-Step Solution

Identify non-vehicular road users with inherent right-of-way precedence.

The pedestrian in the marked crosswalk must be granted right-of-way first.

Traffic law mandates yielding to pedestrians in crosswalks prior to motor vehicle movements.

Apply the first-in, first-out rule for motor vehicles at a four-way stop.

Driver A proceeds next, followed sequentially by Driver B, then Driver C.

Right-of-way at multi-way stops is granted in order of arrival once all vehicles come to a complete stop.

Question 2226Question →

Under ideal dry weather and light traffic conditions, maintaining a minimum following distance of three seconds allows a driver sufficient time to react and stop safely.

True

False

Show answer & explanation

Answer: True

Answer

True

The statement is true because traffic safety standards establish the three-second rule as the safe minimum following distance under good weather and dry road conditions.

Step-by-Step Solution

Identify the standard baseline following distance rule for passenger vehicles under ideal conditions.

The standard safe following distance under clear, dry conditions is at least 3 seconds.

This timing accounts for human reaction time and braking distance at normal speeds.

Key Concept

Three-Second Following Distance Rule

Question 2227Question →

When another vehicle is tailgating your car on a highway, you should increase the following distance between your vehicle and the vehicle directly ahead of you.

True

False

Show answer & explanation

Answer: True

Answer

True. Increasing your following distance when being tailgated creates a safe reaction buffer and reduces the likelihood of sudden braking that could cause a rear-end collision.

When a tailgater is behind you, you lose control over your rear safety margin. To compensate, you must increase your front safety margin by dropping back further from the vehicle ahead. This gives you extra time and space to brake smoothly if traffic stops, helping prevent the vehicle behind from crashing into you.

Step-by-Step Solution

Identify the hazard in the scenario.

The hazard is a tailgating vehicle following closely behind, which limits the stopping buffer at the rear of your car.

Tailgaters cannot stop safely if you are forced to slam on your brakes.

Determine the correct defensive driving action.

Increase the following distance between your vehicle and the car ahead from the standard 3-second rule to 4 or 5 seconds.

A larger front cushion ensures you can bring your vehicle to a gradual, safe stop without requiring sudden braking.

Key Concept

Question 2228Question →

Under standard traffic laws, driving at the posted maximum speed limit of $55\text{ mph}$ is legally compliant even when extreme environmental conditions, such as dense smoke or heavy fog, reduce forward visibility to near zero.

True

False

Show answer & explanation

Answer: False

Answer

False. According to the Basic Speed Law, driving at the posted maximum speed limit is illegal if prevailing conditions, such as dense smoke or fog, make that speed unsafe for current visibility.

The statement is false because the Basic Speed Law explicitly prohibits driving at speeds that are unsafe for current conditions, requiring drivers to reduce speed below the posted maximum whenever visibility or weather is severely compromised.

Step-by-Step Solution

Analyze the relationship between posted speed limits and environmental hazards.

Posted speed limits apply specifically to ideal weather and clear road conditions.

Environmental hazards like dense smoke drastically decrease visibility and reaction distances.

Apply the Basic Speed Law to the scenario.

Operating at

55\text{ mph}

when visibility is near zero violates statutory speed regulation requirements.

The Basic Speed Law requires reducing speed below posted maximums whenever conditions compromise safe vehicle operation.

Question 2229Question →

Under standard traffic regulations, a driver is legally permitted to park a motor vehicle within 10 feet of a fire hydrant, provided the vehicle's hazard warning lights are activated. Determine whether this statement is True or False.

True

False

Show answer & explanation

Answer: False

Answer

The statement is False. Standard traffic safety laws prohibit parking within 15 feet of a fire hydrant regardless of whether hazard lights are activated.

Standard traffic laws strictly enforce a 15-foot minimum parking distance from fire hydrants to maintain unobstructed access for emergency vehicles. Hazard lights do not exempt vehicles from this law.

Step-by-Step Solution

Identify the statutory parking distance limit for fire hydrants.

Standard traffic regulations establish a minimum clearance distance of 15 feet when parking near a fire hydrant.

Firefighting equipment requires immediate, unobstructed access to water sources during emergency operations.

Evaluate whether hazard warning lights alter parking restrictions.

Hazard lights signal a stationary warning but do not provide legal permission to park in prohibited emergency zones.

Statutory parking prohibitions around hydrants apply continuously regardless of vehicle indicator states.

Question 2230Question →

When using hand-and-arm signals to communicate with surrounding traffic, extending the left arm out of the driver's window and pointing it upward indicates an intention to make a left turn.

True

False

Show answer & explanation

Answer: False

Answer

The statement is False. Extending the left arm upward signals an intention to turn right. A left turn is signaled by extending the left arm straight out horizontally.

The statement is false because pointing the left arm upward out of the vehicle window is the universal hand signal for a right turn. To properly signal a left turn, a driver extends their left arm straight out horizontally.

Step-by-Step Solution

Recall standard driver hand-and-arm signaling rules.

Extending the left arm straight out horizontally indicates a left turn. Extending the left arm bent upward at a 90-degree angle indicates a right turn. Extending the left arm bent downward indicates stopping or slowing down.

Standardized manual hand signals ensure predictable communication between motorists when electric turn signals are not functioning or need additional clarity.

Compare the statement's description to the standard rule.

The statement matches the gesture for a right turn, not a left turn.

Because the upward arm posture corresponds to a right turn, the assertion that it indicates a left turn is false.

Question 2231Question →

Four vehicles approach a signalized intersection under different traffic and situational conditions. Based on standard right-of-way rules, in what order should these vehicles proceed through the intersection, from first (highest priority) to last (lowest priority)?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct order of right-of-way precedence from first to last is: (1) The emergency ambulance with active siren and flashing lights, (2) The sedan proceeding straight on a solid green light, (3) The pickup truck making an unprotected left turn on a solid green light, and (4) The compact car turning right on a solid red light after coming to a complete stop.

Standard traffic laws establish a clear hierarchy for intersection right-of-way. Emergency vehicles with active warning lights and sirens always receive top priority. Among non-emergency traffic, vehicles traveling straight on a green signal have priority over turning traffic. An unprotected left turn on green yields to oncoming straight traffic, but takes precedence over vehicles facing a red signal. Finally, turning right on red requires a complete stop and yielding to all traffic proceeding on a green light.

Step-by-Step Solution

Identify emergency vehicle priority

The ambulance with active sirens and lights proceeds first.

Traffic laws require all drivers to yield immediate right-of-way to emergency vehicles operating emergency signals.

Evaluate straight-through traffic on a green signal

The sedan traveling straight through on a solid green light proceeds second.

Straight-through traffic facing a green signal maintains right-of-way over turning vehicles.

Evaluate unprotected left turns on a green signal

The pickup truck making an unprotected left turn on green proceeds third.

Drivers making an unprotected left turn yield to oncoming straight traffic, but have precedence over drivers turning on a red light.

Evaluate right turns on a solid red light

The compact car turning right on red after stopping proceeds fourth (last).

Right turns on red are permitted only after coming to a complete stop and yielding to all vehicles moving on a green signal.

Question 2232Question →

When following a motorcycle on an unpaved gravel road under dry weather conditions, maintaining the standard three-second following distance provides an adequate safety margin because road surface composition does not alter motorcycle braking stability.

True

False

Show answer & explanation

Answer: False

Answer

The statement is False. Following a motorcycle on an unpaved or loose surface requires expanding the following distance beyond the baseline three-second rule to account for reduced traction and vehicle vulnerability.

The statement is false because loose gravel impairs tire traction and stability, especially for motorcycles, requiring trailing drivers to increase their following distance to four seconds or more rather than maintaining the baseline three-second gap.

Step-by-Step Solution

Evaluate the road surface and vehicle dynamics in the scenario.

Identify that an unpaved gravel road presents low-traction conditions for a two-wheeled vehicle.

Motorcycles rely on two contact points, making their traction and balance far more sensitive to loose gravel than four-wheeled passenger cars.

Determine the required safe following distance adjustment.

Recognize that hazardous or unstable road surfaces demand an increased following distance of at least 4 seconds.

Extra space ensures the trailing driver has sufficient time to react if the motorcyclist loses traction or maneuvers suddenly to avoid loose debris.

Question 2233Question →

While driving on a busy city boulevard, a driver notices a motorcycle approaching from behind in the adjacent lane. As the motorcycle moves alongside the rear quarter panel of the car, it disappears from both the rearview mirror and the side mirror. Which action should the driver take to verify the motorcycle's position before attempting any lateral movement?

Perform a physical head turn to check over the left shoulder directly into the blind spot area.

Adjust the exterior side mirror further outward while keeping eyes directed straight ahead.

Rely on the wide-angle view provided by the interior rearview mirror.

Tap the brakes lightly to allow the motorcycle to move back into the side mirror frame.

Show answer & explanation

Answer: Perform a physical head turn to check over the left shoulder directly into the blind spot area.

Answer

The driver should perform a physical head turn to check over the shoulder directly into the blind spot area.

Directly checking over the shoulder allows the driver to visually inspect the vehicle's blind spots where mirrors cannot capture adjacent traffic like motorcycles.

Step-by-Step Solution

Identify the limitations of rear and side mirrors.

Recognize that areas alongside the rear quarter panels are outside the field of view of standard mirrors.

Mirrors leave designated blind spots on both sides of the vehicle.

Execute a chin-to-shoulder head check.

Direct line of sight visually confirms whether a vehicle or motorcycle is in the blind spot.

Head checks provide full visual awareness of spatial areas surrounding the car before any maneuver.

Question 2234Question →

A driver traveling in the center lane of a multi-lane roadway intends to move into the right lane. After activating the turn signal and checking both the rearview mirror and right side-view mirror, which action must the driver perform immediately before steering into the adjacent lane?

Turn your head over your right shoulder to visually check the right blind spot.

Lean forward closer to the windshield to widen the view in the right side-view mirror.

Honk the horn twice to warn any hidden vehicles in the adjacent lane.

Accelerate quickly so any vehicle in the right lane is left behind.

Show answer & explanation

Answer: Turn your head over your right shoulder to visually check the right blind spot.

Answer

Turn your head over your right shoulder to visually check the right blind spot.

Turning your head over your shoulder allows you to directly view areas beside and behind your vehicle that side-view and rearview mirrors cannot reflect.

Step-by-Step Solution

Identify the limitations of rear and side-view mirrors.

Recognize that rearview and side mirrors leave blind spots over the driver's shoulders.

Mirrors cannot display vehicles positioned directly beside the rear quarter panel of your car.

Perform a physical shoulder check before initiating the lateral movement.

Turn your head to look over the shoulder toward the lane you intend to enter.

A direct head check allows visual verification of space that mirror angles miss.

Question 2235Question →

You are driving behind a passenger car on a dry, paved road with clear weather and light traffic. To ensure a safe following cushion, what is the minimum recommended following distance you should maintain?

At least 3 seconds

At most 1 second

Always drive at the maximum posted speed limit regardless of the distance to the car ahead

Exactly one car length for every 30 mph of speed

Show answer & explanation

Answer: At least 3 seconds

Answer

At least 3 seconds of following distance should be maintained under normal driving conditions.

Under normal, dry road and clear weather conditions, driver safety standards specify maintaining at least a 3-second following distance. This interval ensures adequate perception-reaction time and stopping distance if the leading vehicle brakes suddenly.

Step-by-Step Solution

Identify the standard safety guideline for following distance under normal, dry weather conditions.

The standard safe following distance recommended by driver safety manuals is the 3-second rule.

The 3-second rule accounts for human reaction time and the physical stopping distance required for passenger vehicles at various speeds.

Evaluate the options against safe driving practices.

Maintaining at least 3 seconds ensures adequate space cushion, whereas shorter intervals or fixed car-length rules are unsafe or insufficient.

Shorter times do not allow sufficient reaction buffer if the vehicle ahead stops suddenly.

Question 2236Question →

You are driving on a one-way street when an emergency vehicle displaying flashing lights and sounding a siren approaches from behind. Which of the following actions are you legally required to take?

Pull over to the nearest curb or edge of the roadway, clear of any intersection, and remain stopped until the emergency vehicle passes.

Maintain your speed and lane position while turning on your hazard lights so the emergency vehicle driver knows you see them.

Come to an immediate complete stop in your current lane of travel to allow the emergency vehicle to steer around your vehicle.

Accelerate to the posted speed limit to reach the next intersection before pulling over to the right side.

Show answer & explanation

Answer: Pull over to the nearest curb or edge of the roadway, clear of any intersection, and remain stopped until the emergency vehicle passes.

Answer

Pull over to the nearest curb or edge of the roadway, clear of any intersection, and remain stopped until the emergency vehicle passes.

When an emergency vehicle with active siren and flashing lights approaches on any roadway, including a one-way street, drivers must yield the right-of-way by moving as far as safely possible to the nearest edge or curb clear of any intersection and stopping until the vehicle has passed.

Step-by-Step Solution

Recognize the approaching emergency vehicle

Identify active sirens and flashing lights indicating an emergency response.

Emergency vehicles operating lights and sirens have immediate right-of-way over standard traffic.

Locate the nearest edge of the street clear of intersections

Determine a safe path toward the nearest curb (left or right on a one-way street, clear of any intersection).

Blocking intersections or stopping in travel lanes prevents emergency vehicles from passing safely.

Drive to the curb and stop completely

Position your vehicle parallel to the edge of the street and come to a complete stop until all emergency vehicles pass.

This fully opens the travel lane for emergency responders.

Question 2237Question →

A driver is traveling on an unlit rural road at night where the posted speed limit is $50\text{ mph}$ . Heavy fog begins to roll in, reducing the driver's forward visibility to approximately $100\text{ feet}$ . Under the Basic Speed Law, what is the driver legally required to do?

Maintain

50\text{ mph}

as long as the vehicle remains within the marked lane lines.

Reduce speed to a rate that allows the vehicle to come to a complete stop within the visible distance ahead.

Increase speed slightly to exit the fog zone as quickly as possible.

Maintain a constant speed of

45\text{ mph}

because posted speed limits allow a

5\text{ mph}

tolerance in adverse weather.

Show answer & explanation

Answer: Reduce speed to a rate that allows the vehicle to come to a complete stop within the visible distance ahead.

Answer

The driver must reduce speed to a rate that allows the vehicle to stop safely within the distance visible ahead.

Under the Basic Speed Law, drivers must adjust their speed to what is safe for current road and weather conditions. When visibility is severely impaired by fog, the driver must reduce speed so that total stopping distance does not exceed the illuminated or visible distance ahead.

Step-by-Step Solution

Identify the environmental hazard and its impact on driving safety.

Heavy fog reduces forward visibility to

100\text{ feet}

, significantly limiting the driver's reaction time and visual buffer.

50\text{ mph}

, total stopping distance (reaction distance plus braking distance) typically exceeds

200\text{ feet}

, which is far greater than the

100\text{ feet}

of visibility.

Apply the statutory Basic Speed Law to the scenario.

The law mandates that no person shall drive a vehicle at a speed greater than is reasonable or prudent under existing conditions.

Posted speed limits represent maximum allowable speeds under ideal conditions, not guaranteed safe speeds under adverse weather or reduced visibility.

Question 2238Question →

You are driving behind a large commercial truck on a two-lane road during a rainstorm as you enter a school zone with active flashing lights displaying a $20\text{ mph}$ limit. The standard posted speed limit for this road segment is normally $35\text{ mph}$ . Under these combined road and weather conditions, how should you legally and safely adjust your speed and following distance?

Reduce your speed to

20\text{ mph}

or lower to obey the active school zone speed limit and Basic Speed Law, while increasing your following distance to at least 4 to 5 seconds.

Maintain

35\text{ mph}

as long as no children are physically present on the sidewalks or crosswalks at that exact moment.

Reduce your speed to

20\text{ mph}

to comply with the school zone, but maintain the standard 3-second following distance behind the truck.

Drive at

35\text{ mph}

while increasing your following distance to 5 seconds, assuming the additional gap safely compensates for traveling above the school zone limit.

Show answer & explanation

Answer: Reduce your speed to $20\text{ mph}$ or lower to obey the active school zone speed limit and Basic Speed Law, while increasing your following distance to at least 4 to 5 seconds.

Answer

Reduce your speed to

20\text{ mph}

or lower to obey the active school zone speed limit and Basic Speed Law, while increasing your following distance to at least 4 to 5 seconds.

The correct response recognizes two essential safety principles: active school zone flashing lights require an immediate reduction to the posted speed limit (

20\text{ mph}

), and wet roads combined with trailing a large truck necessitate expanding the following distance buffer beyond the standard 3-second minimum to 4 seconds or more.

Step-by-Step Solution

Determine the legal speed limit based on active zone signs and road conditions

The speed limit drops to

20\text{ mph}

due to the active flashing school zone lights, and may need to be lower if rain severely impairs traction.

Traffic law dictates that active school zone signals supersede regular posted limits, and the Basic Speed Law mandates driving at a safe speed for current weather conditions.

Evaluate required following distance behind a large commercial vehicle on wet pavement

Increase following distance from the standard 3 seconds to 4-5 seconds or more.

Large trucks block forward line-of-sight, and wet road surfaces significantly increase vehicle braking distances.

Question 2239Question →

True or False: When an emergency vehicle using flashing lights and a siren approaches from behind, you should immediately bring your vehicle to a complete stop in your current lane of traffic to let it pass.

True

False

Show answer & explanation

Answer: False

Answer

False. When an emergency vehicle approaches with active lights and sirens, drivers must safely steer toward the right edge or curb of the road and stop, rather than stopping in an active lane of traffic.

The statement is false. Traffic regulations dictate that upon the approach of an emergency vehicle displaying red lights and sounding a siren, drivers must yield the right-of-way by driving to a position parallel to, and as close as possible to, the right-hand edge or curb of the roadway and stopping until the emergency vehicle has passed.

Step-by-Step Solution

Identify the driver's legal duty upon hearing or seeing an approaching emergency vehicle.

Drivers must clear the path of the emergency vehicle immediately and safely.

Emergency vehicles require an unobstructed lane of travel to reach scenes safely and quickly.

Evaluate the action described in the statement (stopping immediately in the current lane).

Stopping dead in a travel lane blocks traffic flow and potentially blocks the emergency vehicle's path.

Safety regulations mandate moving to the right shoulder or curb before coming to a stop.

Question 2240Question →

A motorist stops to park a vehicle facing downhill on a street segment with an unpaved shoulder and no raised curb. Which wheel positioning procedure must the motorist follow to properly secure the vehicle?

Turn the front wheels toward the right edge of the roadway.

Turn the front wheels to the left, facing into the lane of traffic.

Keep the front wheels pointed straight in alignment with the roadway.

Turn the front wheels toward the roadway center until the parking brake is set.

Show answer & explanation

Answer: Turn the front wheels toward the right edge of the roadway.

Answer

Turn the front wheels toward the right edge of the roadway.

When parking facing downhill, whether a curb is present or not, turning the front wheels to the right ensures that gravity will roll the vehicle away from active travel lanes and onto the shoulder or curb if the brakes fail.

Step-by-Step Solution

Determine the direction of the incline and presence of a curb

The vehicle is facing downhill on a street without a raised curb.

Parking rules for hill parking depend on whether the vehicle faces uphill or downhill and whether a curb is present.

Apply the rule for downhill parking without a curb

The front wheels must be turned toward the right shoulder/edge of the road.

If the vehicle rolls, turning the wheels to the right guides the front of the car off the pavement away from moving traffic.
