Difficulty: Very hardEmergency Vehicles, School Buses, and Work Zones

You are driving on a four-lane divided highway separated by an unpaved physical median. A school bus traveling on the opposite side of the median stops and activates its flashing red lights with stop arm extended. At the same moment, an emergency ambulance with sounding sirens approaches rapidly from behind in your lane, while a stationary roadside service vehicle displaying flashing yellow warning lights is parked on the right shoulder 200 feet ahead. Which set of driving actions must you legally take to navigate this scenario correctly?

  1. Safely maneuver to yield the right-of-way to the emergency vehicle behind you, reduce speed when passing the stationary service vehicle, and proceed without stopping for the school bus across the physical median.Answer
  2. B
    Bring your vehicle to an immediate complete stop in your lane to observe the school bus flashing red lights, prioritizing the bus stop over the approaching ambulance behind you.
  3. C
    Maintain your lane position and posted speed limit to avoid sudden maneuvers while the ambulance passes on the left, taking no special action for the shoulder service vehicle.
  4. D
    Pull over onto the central physical median and come to a complete stop until the service vehicle's flashing yellow lights are turned off.

Answer

Safely maneuver to yield the right-of-way to the emergency vehicle behind you, reduce speed when passing the stationary service vehicle, and proceed without stopping for the school bus across the physical median.
The correct response accurately applies all three traffic laws simultaneously. First, vehicles traveling opposite a school bus on a divided highway separated by a physical median are not legally required to stop. Second, drivers must yield right-of-way to an emergency vehicle giving audible and visual signals by safely clearing its path. Third, Move-Over laws dictate that drivers slow down and exercise caution when passing stationary service vehicles displaying flashing yellow lights on the shoulder.

Step-by-Step Solution

1
Evaluate the school bus requirement on a divided highway.
Because the highway is divided by a physical unpaved median, traffic moving in the opposite direction of the school bus is legally exempt from stopping.
Divided highway laws recognize physical barriers as effective separation preventing children from crossing into opposing lanes.
2
Address the emergency vehicle approaching from behind.
Safely yield right-of-way by moving toward the right side of the road or clearing the lane as appropriate so the ambulance can pass without obstruction.
Traffic laws strictly require drivers to yield right-of-way to emergency vehicles operating active sirens and emergency lights.
3
Apply Move-Over regulations for the stationary roadside vehicle.
Slow down to a safe speed below the posted limit and, if safe, move over one lane away from the stationary service vehicle on the right shoulder.
Move-Over laws protect roadside service workers and emergency personnel operating on highway shoulders.
