A motorist is traveling along a road past an elementary school on a weekday morning while the amber beacons on the school zone sign are actively flashing. The standard statutory speed limit for the roadway is $35\text{ mph}$ , but the sign specifies a reduced speed limit of $20\text{ mph}$ when flashing. Due to a recent oil spill combined with light rain, the roadway surface has become extremely slick, such that traveling above $12\text{ mph}$ renders stopping within a safe distance impossible. The motorist maintains a constant speed of $20\text{ mph}$ , believing full compliance with the active school zone sign. Which of the following statements correctly evaluates the driver's speed under traffic regulation laws?

The driver is violating the Basic Speed Law because hazardous road surface conditions require driving at a speed slower than the posted maximum limit to ensure safety.

The driver is fully compliant with all traffic laws because active posted school zone limits set the mandatory statutory speed regardless of surface traction.

The driver is violating traffic rules by failing to maintain the standard

35\text{ mph}

roadway speed limit, as school zone reductions apply only on dry pavement.

The driver is legally required to maintain

20\text{ mph}

to avoid creating an unlawful traffic impediment for trailing vehicles in a designated school area.

Show answer & explanation

Answer: The driver is violating the Basic Speed Law because hazardous road surface conditions require driving at a speed slower than the posted maximum limit to ensure safety.

Answer

The driver is violating the Basic Speed Law because hazardous road surface conditions require driving at a speed slower than the posted maximum limit to ensure safety.

The Basic Speed Law dictates that no person shall drive a vehicle at a speed greater than is reasonable or prudent having due regard for weather, visibility, traffic, and surface conditions. Because slick oil and rain prevent safe stopping above

12\text{ mph}

, driving at

20\text{ mph}

violates the law despite being at the posted maximum school zone limit.

Step-by-Step Solution

Identify the statutory posting vs. physical roadway conditions

The active posted school zone speed limit is

20\text{ mph}

, but the road surface is extremely slick due to rain and oil.

Traffic law distinguishes between maximum posted limits under ideal conditions and required speeds during hazardous conditions.

Apply the Basic Speed Law to the situational hazard

The Basic Speed Law mandates that a driver must never operate a vehicle at a speed greater than is reasonable or prudent given actual weather, visibility, traffic, and roadway surface conditions.

Even though

20\text{ mph}

is posted on the school zone sign, driving

20\text{ mph}

when safe stopping requires

12\text{ mph}

or less constitutes an illegal speed.

Select the option that reflects the overriding authority of the Basic Speed Law

The option stating that the driver violates the Basic Speed Law because surface conditions require a speed lower than the posted limit is correct.

Posted speed limits represent maximum legal speeds under ideal conditions, not an absolute right to travel at that speed when hazards are present.

Question 902Question →

Under standard traffic laws, a driver is legally permitted to exceed the posted maximum speed limit if necessary to match the flow of surrounding traffic.

True

False

Show answer & explanation

Answer: False

Answer

False. Drivers must never exceed the posted maximum speed limit, even if surrounding traffic is driving above the posted limit.

The statement is false because posted speed limits establish the absolute upper boundary of legal speed. Drivers are required to obey posted maximum limits even if surrounding vehicles are driving faster.

Step-by-Step Solution

Identify the statutory rule governing posted speed limits.

The posted maximum speed limit is a legal ceiling set for ideal driving conditions.

Traffic safety regulations establish speed limits as strict legal maximums.

Assess whether the 'flow of traffic' creates an exemption to the legal limit.

Traveling with faster traffic does not legalise exceeding the posted speed limit.

Statutory speed limit laws apply to each driver individually regardless of other road users' actions.

Question 903Question →

When applying for or renewing a state driver's license, what legal obligation does a motorist automatically accept under implied consent principles?

Agreement to submit to a chemical test of breath, blood, or urine when lawfully arrested for suspected impaired driving.

Agreement to undergo unannounced random drug screening tests to maintain active driving privileges.

Agreement to waive the right to a trial if cited for driving with a measurable blood alcohol concentration.

Agreement that chemical testing can only be administered if an attorney is present at the scene.

Show answer & explanation

Answer: Agreement to submit to a chemical test of breath, blood, or urine when lawfully arrested for suspected impaired driving.

Answer

The motorist automatically agrees to submit to a post-arrest chemical test of breath, blood, or urine whenever lawfully requested by law enforcement.

Implied consent statutes dictate that operating a motor vehicle on public roads acts as an automatic agreement to submit to evidentiary chemical tests (breath, blood, or urine) if lawfully arrested for driving while impaired.

Step-by-Step Solution

Analyze the legal definition of implied consent.

Implied consent means that receiving the privilege to drive on public roads carries a statutory obligation to comply with chemical testing.

State licensing authorities condition road access on cooperation with impaired driving enforcement.

Identify when the mandatory obligation is triggered.

The requirement triggers immediately after a driver is lawfully arrested under suspicion of impaired driving.

Refusal to take the evidentiary test triggers mandatory administrative license suspension penalties regardless of court verdict.

Question 904Question →

A white rectangular regulatory sign reading 'EMERGENCY STOPPING ONLY' permits drivers to stop on the highway shoulder to adjust a vehicle's navigation system.

True

False

Show answer & explanation

Answer: False

Answer

The statement is False. Regulatory signs reading 'EMERGENCY STOPPING ONLY' restrict stopping on highway shoulders strictly to urgent vehicle or medical emergencies. Stopping for routine adjustments like setting up navigation is illegal.

The statement is false because regulatory signs stating 'EMERGENCY STOPPING ONLY' enforce a strict legal prohibition against stopping on highway shoulders for any non-emergency reason, including adjusting navigation tools.

Step-by-Step Solution

Identify the classification and legal authority of the sign.

The 'EMERGENCY STOPPING ONLY' sign is a white rectangular regulatory sign that enforces legal controls on shoulder usage.

Regulatory signs inform drivers of specific traffic laws and rules that must be strictly obeyed.

Evaluate whether adjusting a navigation system meets the legal standard for an emergency.

Adjusting navigation equipment is a routine driver convenience task, not a vehicle breakdown or medical hazard.

Designated emergency shoulders are reserved exclusively for situations where continuing to drive poses an immediate safety risk.

Question 906Question →

If a uniformed traffic officer directing vehicles around a roadway obstruction explicitly signals a driver to cross a double solid yellow line into an opposing traffic lane, the driver is legally required to follow the officer's direction despite the standard pavement marking prohibition.

True

False

Show answer & explanation

Answer: True

Answer

True. Directions provided by a uniformed traffic officer supersede all static pavement markings, signs, and traffic signals.

The statement is True because authorized traffic officers hold complete legal authority to override static traffic control features—including double solid yellow pavement lines—when managing traffic safety around hazards.

Step-by-Step Solution

Determine the legal hierarchy of traffic control authority.

Uniformed traffic officers and authorized emergency personnel possess the highest level of authority on public roadways.

Live traffic control personnel are tasked with actively managing dynamic road hazards, incidents, or construction situations that static devices cannot accommodate.

Resolve the conflict between the pavement marking rule and the officer's signal.

The officer's directive to cross the double solid yellow line legally supersedes the standard pavement marking rule.

Traffic laws explicitly establish that drivers must obey any lawful order or direction of a police officer, regardless of conflicting static road markings or signals.

Question 907Question →

A driver is traveling along an urban arterial street with a posted maximum speed limit of $35\text{ mph}$ . Upon approaching a designated school zone, the driver sees a regulatory sign reading " $25\text{ mph}$ WHEN CHILDREN ARE PRESENT." Children are visibly playing in an enclosed schoolyard separated from the street by a fence, but none are on the sidewalk or near the crosswalk. Simultaneously, a heavy sudden rainstorm creates deep standing water on the asphalt. What is the driver's legal obligation regarding vehicle speed in this situation?

The driver must maintain exactly

35\text{ mph}

because children are behind a fence and posted limits are mandatory minimums.

The driver must reduce speed below

25\text{ mph}

to a rate that is safe for the standing water and hazardous road conditions.

The driver is strictly required to drive at

25\text{ mph}

because children are nearby within the school property grounds.

The driver may legally drive at

35\text{ mph}

as long as windshield wipers are set to maximum speed.

Show answer & explanation

Answer: The driver must reduce speed below $25\text{ mph}$ to a rate that is safe for the standing water and hazardous road conditions.

Answer

The driver must reduce speed below

25\text{ mph}

to a rate that is safe for the standing water and hazardous road conditions.

Under the Basic Speed Law, posted speed limits represent maximum allowable speeds under ideal driving conditions. When hazardous conditions exist—such as heavy rain and standing water that present hydroplaning risks—drivers are legally required to reduce their speed to a rate that is safe and prudent for those specific conditions, even if that speed is well below all posted regulatory signs.

Step-by-Step Solution

Analyze the posted regulatory speed limits

The standard posted maximum speed limit is

35\text{ mph}

, and the school zone conditional limit is

25\text{ mph}

Establishing static regulatory boundaries sets the upper ceiling under normal conditions.

Evaluate the Basic Speed Law requirement against current environmental hazards

Standing water creates severe hydroplaning hazards, requiring a speed lower than statutory maximums.

The Basic Speed Law dictates that no person shall drive a vehicle at a speed greater than is reasonable or prudent having due regard for weather, visibility, traffic, and surface conditions.

Synthesize the overriding speed regulation rule

Adverse weather and standing water override posted limits, legally obligating the driver to slow to whatever reduced speed ensures control and safety.

Posted speed limits apply only under ideal driving conditions; hazardous conditions require further speed reduction regardless of posted signs.

Question 908Question →

Participating in an unauthorized speed contest or street race on a public highway is classified as a serious traffic offense that can result in mandatory driver license suspension upon a first conviction.

True

False

Show answer & explanation

Answer: True

Answer

The statement is true because engaging in an unauthorized street race or speed contest on a public roadway is legally defined as a serious traffic offense with mandatory penalties including license suspension.

Participating in a speed contest on public highways involves deliberate disregard for traffic safety. Licensing authorities and traffic courts classify this as a major offense, imposing mandatory driver license suspensions even for first-time offenders.

Step-by-Step Solution

Identify the legal classification of unauthorized speed contests on public roads.

Unauthorized street racing is classified as a serious moving violation and misdemeanor offense due to severe public safety risks.

Traffic laws categorize high-risk driving behaviors like street racing under serious traffic violations.

Evaluate the statutory penalties associated with a first conviction for street racing.

Statutes mandate severe penalties including license suspension, points, and court fines upon conviction.

DMV statutes enforce mandatory administrative license actions to deter hazardous organized or spontaneous speed contests.

Question 909Question →

When facing a flashing yellow arrow signal in a designated left-turn lane, drivers are legally permitted to turn left without yielding to oncoming traffic.

True

False

Show answer & explanation

Answer: False

Answer

False. A flashing yellow arrow allows left turns, but drivers must yield the right-of-way to oncoming traffic and pedestrians before turning.

A flashing yellow arrow allows drivers to turn left after yielding to oncoming traffic and pedestrians. Because the turn is unprotected, proceeding without yielding is a traffic violation and collision hazard.

Step-by-Step Solution

Identify the legal meaning of a flashing yellow arrow signal.

A flashing yellow arrow indicates that left turns are allowed, but the movement is unprotected.

Traffic signal laws designate flashing yellow arrows to alert drivers that turning traffic does not have priority over straight-through traffic.

Determine right-of-way requirements for unprotected left turns.

The turning driver must yield to oncoming vehicles and pedestrians crossing the intersection.

Oncoming traffic traveling straight has the green light and right-of-way during a flashing yellow arrow phase.

Question 910Question →

At an intersection controlled by a steady solid red arrow pointing right, a driver is legally permitted to execute a right turn after coming to a complete stop and yielding to cross traffic and pedestrians.

True

False

Show answer & explanation

Answer: False

Answer

False. A driver facing a steady solid red arrow signal is strictly prohibited from turning in the direction of the arrow and must remain stopped until a green signal appears.

A steady solid red arrow means a driver must come to a complete stop and stay stopped until a permissive signal (such as a green light or green arrow) turns on. Drivers may not turn right on a solid red arrow, even after coming to a full stop and yielding.

Step-by-Step Solution

Identify the signal type described in the scenario.

The traffic signal is a steady solid red arrow pointing right.

Right-of-way and turning rules depend specifically on whether a light is circular or an arrow.

Recall the legal rule for steady solid red arrow signals.

A steady solid red arrow means stop and forbids movement in the indicated direction.

Standard traffic regulations allow right turns on steady circular red lights after stopping, but prohibit turns against solid red arrows.

Evaluate the correctness of the statement.

The assertion that a driver may turn right on a solid red arrow after stopping is false.

The driver must remain stopped until a green arrow or green light is shown.

Question 911Question →

While driving on a multi-lane roadway, you approach a crosswalk equipped with a Pedestrian Hybrid Beacon (HAWK signal). The beacon sequence has just transitioned to alternating flashing red lights. What is the legally required action for a driver?

Come to a complete stop, yield the right-of-way to any pedestrians in or entering the crosswalk, and then proceed if clear.

Remain completely stopped until all signal lights turn dark, even if pedestrians have safely cleared the crosswalk.

Slow down and proceed through the crosswalk with caution without coming to a full stop if no pedestrians are present.

Maintain posted speed because flashing red lights on a hybrid beacon are strictly advisory indicators.

Show answer & explanation

Answer: Come to a complete stop, yield the right-of-way to any pedestrians in or entering the crosswalk, and then proceed if clear.

Answer

Come to a complete stop, yield the right-of-way to any pedestrians in or entering the crosswalk, and then proceed if clear.

When a Pedestrian Hybrid Beacon displays alternating flashing red lights, drivers are required to bring their vehicle to a complete stop at the stop line or crosswalk. After stopping and yielding the right-of-way to any pedestrians crossing the roadway, drivers may legally proceed through the crosswalk if it is safe and clear to do so.

Step-by-Step Solution

Identify the traffic signal type and current light state

The signal is a Pedestrian Hybrid Beacon displaying alternating flashing red lights.

Different phases of hybrid beacons carry distinct legal mandates for approaching drivers.

Apply the rule for alternating flashing red lights on hybrid beacons

Treat the flashing red signal as a stop sign requirement.

Traffic law mandates a full stop before entering the crosswalk when facing flashing red lights.

Check for pedestrians and evaluate right-of-way

Yield to any pedestrians crossing or preparing to cross, and proceed when the path is safe and clear.

Drivers may move through the crosswalk during the flashing red phase once pedestrians have safely cleared.

Question 912Question →

A motorist is driving on a multi-lane highway with a standard speed limit of $65\text{ mph}$ and enters a designated construction area displaying a regulatory sign stating $45\text{ mph}$ when workers are present. Active road construction crews are working near the shoulder, but other vehicles are traveling at $55\text{ mph}$ . Under speed regulation laws, which of the following actions is the driver legally required to take?

Maintain a speed of no more than

45\text{ mph}

, reducing speed further if road conditions require, regardless of surrounding traffic.

Accelerate to

55\text{ mph}

to match the surrounding flow of traffic and prevent obstructing other vehicles.

Maintain

65\text{ mph}

as long as construction vehicles and equipment do not physically block the active driving lane.

Observe the

45\text{ mph}

limit only if flashing yellow beacon lights are active on the work zone signs.

Show answer & explanation

Answer: Maintain a speed of no more than $45\text{ mph}$ , reducing speed further if road conditions require, regardless of surrounding traffic.

Answer

The driver must maintain a speed of no more than

45\text{ mph}

, adjusting lower if conditions warrant, regardless of the faster surrounding traffic flow.

Posted regulatory work zone limits become active and legally binding when the specified condition—workers present—is satisfied. Drivers are legally obligated to obey the reduced speed limit regardless of whether other surrounding vehicles are exceeding it.

Step-by-Step Solution

Identify the regulatory speed sign requirements.

The work zone has a posted conditional speed limit of

45\text{ mph}

when workers are present.

Work zone speed limits are regulatory limits designed to protect road crews and drivers.

Determine whether the condition for the speed limit is met.

Workers are actively present along the shoulder, activating the legal

45\text{ mph}

speed limit.

When the posted condition occurs, the reduced limit becomes legally binding.

Evaluate the legality of matching surrounding traffic speed.

Surrounding traffic traveling at

55\text{ mph}

is breaking the posted limit and does not grant legal exemption to match their speed.

The law requires adherence to posted limits regardless of other drivers' behavior.

Question 913Question →

You are driving on a two-lane rural highway marked with a broken yellow centerline and wish to overtake a slow-moving vehicle ahead. As you begin your maneuver to pass, you observe a crossroad intersection located 75 feet ahead. Which of the following statements correctly identifies the statutory legality of completing this pass?

The passing maneuver is illegal because drivers are prohibited from driving on the left side of the roadway when approaching within 100 feet of an intersection, regardless of centerline markings.

The passing maneuver is legal because a broken yellow centerline grants permission to cross into the oncoming lane at any location.

The passing maneuver is legal provided you complete the pass and return to your right lane before crossing the midpoint of the intersection.

The passing maneuver is illegal only if the broken yellow line transitions to a solid double yellow line before the intersection boundary.

Show answer & explanation

Answer: The passing maneuver is illegal because drivers are prohibited from driving on the left side of the roadway when approaching within 100 feet of an intersection, regardless of centerline markings.

Answer

The passing maneuver is illegal because drivers are prohibited from driving on the left side of the roadway when approaching within 100 feet of an intersection, regardless of centerline markings.

Under standard traffic regulations, drivers may not drive on the left side of the roadway when approaching or traversing within 100 feet of an intersection. Although a broken yellow centerline generally allows passing when safe, statutory safety rules near intersections supersede lane line indicators.

Step-by-Step Solution

Identify the general rule for the pavement marking.

A broken yellow centerline indicates that traffic in adjacent lanes flows in opposite directions and passing is generally permitted when clear.

Establishes baseline permission for center lane markings.

Identify statutory restrictions that override pavement markings.

Traffic codes establish specific safety zones where driving on the left side of the road (passing) is unlawful, specifically within 100 feet of an intersection, railroad crossing, bridge, or tunnel.

Determines legal boundaries when multiple regulatory factors overlap.

Apply the distance constraint to the scenario.

Since the intersection is 75 feet ahead, it falls within the prohibited 100-foot zone.

Concludes that the maneuver is illegal despite the broken yellow line.

Question 914Question →

Because motorcyclists frequently downshift to control their speed, a motorcycle can slow down significantly without its rear brake light illuminating.

True

False

Show answer & explanation

Answer: True

Answer

True

The statement is true because downshifting slows the motorcycle down using engine drag rather than brake pads, meaning the brake light does not turn on to warn drivers following behind.

Step-by-Step Solution

Analyze how motorcycle deceleration mechanisms operate in traffic.

Motorcyclists frequently downshift gears to slow down via engine braking instead of engaging the hand or foot brake controls.

Engine braking reduces vehicle speed without closing the electrical circuit that turns on the brake light.

Identify the safety implication for following motor vehicles.

Following drivers must maintain extra following distance and rely on visual cues beyond just the brake lights to notice changes in speed.

Relying strictly on brake lights can cause trailing drivers to tailgating or crash into a decelerating motorcycle.

Question 915Question →

A driver is traveling along a rural two-lane highway with a posted maximum speed limit of $55\text{ mph}$ . Heavy fog suddenly reduces visibility to less than $100\text{ feet}$ . Vehicles behind the driver begin tailgating and flashing their headlights, urging the driver to speed up. To maintain a safe stopping distance within the visible distance ahead, the driver decelerates to $25\text{ mph}$ . Which of the following statements correctly evaluates the driver's speed choice under speed regulation laws?

The driver is complying with the Basic Speed Law, which mandates driving at a safe, reduced speed dictated by hazardous visibility regardless of posted maximum limits or pressure from rear traffic.

The driver is violating traffic laws by impeding the flow of traffic, because drivers are legally required to match the speed of trailing vehicles on two-lane highways.

The driver is legally protected to drive at the posted

55\text{ mph}

limit because static regulatory signs establish an absolute safe speed ceiling that immunizes drivers from traffic citations.

The driver is required to maintain

55\text{ mph}

unless a temporary variable speed sign or law enforcement officer explicitly lowers the posted numerical speed limit.

Show answer & explanation

Answer: The driver is complying with the Basic Speed Law, which mandates driving at a safe, reduced speed dictated by hazardous visibility regardless of posted maximum limits or pressure from rear traffic.

Answer

The driver is complying with the Basic Speed Law, which mandates driving at a safe, reduced speed dictated by hazardous visibility regardless of posted maximum limits or pressure from rear traffic.

Under the Basic Speed Law, drivers must never travel faster than is safe for current conditions regardless of the posted maximum speed limit. In severe fog with less than

100\text{ feet}

of visibility, slowing down to

25\text{ mph}

ensures the driver can stop within their clear range of vision, fulfilling legal requirements despite pressure from trailing vehicles.

Step-by-Step Solution

Analyze prevailing environmental and road conditions.

Dense fog restricts visibility to under

100\text{ feet}

, creating a severe stopping sight distance hazard.

Vehicle stopping distance at

55\text{ mph}

significantly exceeds

100\text{ feet}

, making maximum posted speed unsafe.

Apply the statutory Basic Speed Law framework.

The Basic Speed Law requires operating at a prudent speed given current hazards, overriding the posted maximum limit of

55\text{ mph}

Posted numerical speed limits only apply under ideal weather and traffic conditions.

Evaluate trailing traffic pressure vs. statutory speed duties.

Tailgating vehicles do not relieve a driver of the duty to maintain a speed that allows stopping safely within clear sight distance.

Safety and visibility bounds supersede pressure from other drivers attempting to exceed safe speeds.

While driving on a multi-lane roadway where traffic flows in the same direction, you observe a single solid white line painted between your lane and the adjacent lane. What does this pavement marking indicate?

Lane changing is discouraged, and drivers should remain in their lane unless necessary to avoid a hazard.

Traffic in the adjacent lane is traveling in the opposite direction.

Drivers are encouraged to change lanes frequently to equalize traffic flow.

Vehicles in this lane are required to make a complete stop before crossing the line.

Show answer & explanation

Answer: Lane changing is discouraged, and drivers should remain in their lane unless necessary to avoid a hazard.

Answer

A single solid white line between lanes moving in the same direction indicates that lane changing is discouraged and drivers should stay in their lane.

A single solid white line between travel lanes traveling in the same direction is used to discourage lane changes and channel traffic safely, such as when approaching an intersection or navigating a narrow corridor.

Step-by-Step Solution

Analyze the line color.

White lines separate lanes of traffic traveling in the same direction.

Yellow lines are reserved for separating opposing traffic flows.

Analyze the line pattern.

A solid pattern indicates restricted or discouraged lane movement compared to a broken line.

Solid white lines are placed in areas such as near intersections or hazard zones where switching lanes creates extra danger.

Question 919Question →

In standard traffic law, when no speed limit signs are posted, the statutory maximum speed limit for an alley is identical to the statutory maximum speed limit for a residential district.

True

False

Show answer & explanation

Answer: False

Answer

False. Under standard statutory traffic rules, the unposted speed limit for an alleyway is restricted to

15\text{ mph}

, whereas the unposted speed limit for a residential district is

25\text{ mph}

The claim is false because state vehicle codes designate distinct statutory speed limits based on roadway classification when signs are absent. An unposted alley carries a statutory limit of

15\text{ mph}

, whereas an unposted residential area carries a statutory limit of

25\text{ mph}

Step-by-Step Solution

Identify the unposted statutory speed limit for residential roadways.

The default statutory limit for residential and business districts is established as

25\text{ mph}

unless signed otherwise.

Vehicle codes set standard baseline limits for residential areas to maintain predictable safety standards.

Identify the unposted statutory speed limit specifically designated for alleys.

The default statutory limit for an alleyway is restricted to

15\text{ mph}

Alleys present unique environmental risks, including blind property corners and lack of sidewalks, requiring a strictly lower statutory ceiling.

Compare the two statutory classifications to evaluate the statement.

The limits are distinct (

15\text{ mph}

25\text{ mph}

), making the assertion of identical limits false.

Different roadway classifications carry specific statutory speed ceilings when signs are absent.

Question 920Question →

A motorist is driving in the left-hand lane of a multi-lane highway where the posted maximum speed limit is $55\text{ mph}$ . Weather and road conditions are clear, traffic is moving smoothly, and the vehicle has no mechanical issues. However, the motorist travels at $25\text{ mph}$ , causing multiple vehicles behind them to brake unexpectedly and form a long traffic queue. Which of the following statements correctly describes the legal status of this driver's speed choice under standard speed regulation laws?

The driver is violating traffic law by traveling at an unreasonably slow speed that blocks or impedes the normal flow of traffic.

The driver is fully compliant with the law because any speed below the posted maximum is automatically considered legal.

The driver is legally permitted to maintain this speed as long as their hazard warning lights remain continuously activated.

The driver is only required to increase speed if an emergency vehicle displaying flashing lights approaches from behind.

Show answer & explanation

Answer: The driver is violating traffic law by traveling at an unreasonably slow speed that blocks or impedes the normal flow of traffic.

Answer

The driver is violating traffic law by traveling at an unreasonably slow speed that blocks or impedes the normal flow of traffic.

Under standard traffic laws, drivers must not operate a vehicle at such a slow speed as to impede or block the normal and reasonable movement of traffic, except when reduced speed is necessary for safe operation (e.g., severe weather or heavy congestion). Traveling

25\text{ mph}

in a

55\text{ mph}

zone under clear conditions creates a severe hazard.

Step-by-Step Solution

Analyze the driving conditions and driver behavior.

The driver is traveling at

25\text{ mph}

in a

55\text{ mph}

zone under clear, normal conditions, causing trailing traffic to queue up.

Speed rules apply to both maximum limits and minimum speed regulations depending on traffic flow.

Apply traffic safety laws regarding slow-moving vehicles and traffic flow.

Driving significantly slower than prevailing traffic when road and weather conditions do not require it creates a hazard and constitutes illegal impeding of traffic.

Traffic laws prohibit drivers from impeding the normal and reasonable movement of traffic without a valid safety justification.
