Difficulty: MediumEmergency Vehicles, School Buses, and Work Zones

On a single-lane roadway in each direction, a motorist approaches a parked utility service vehicle operating with active flashing lights on the shoulder. Traffic in the opposite lane makes merging left impossible. Under state Move-Over regulations, what action is the driver legally required to take?

  1. Reduce speed to significantly below the posted limit and proceed past the vehicle with caution.Answer
  2. B
    Stop completely in the travel lane until all emergency lights are turned off.
  3. C
    Maintain the posted speed limit while driving as close to the center line as possible.
  4. D
    Accelerate quickly to pass the stationary vehicle and clear the area immediately.

Answer

The driver must reduce speed to significantly below the posted limit and proceed past the vehicle with caution.
State Move-Over laws mandate that when a driver cannot safely change lanes away from a stationary emergency or utility vehicle displaying active lights, they must reduce their speed significantly below the posted speed limit and proceed with heightened caution.

Step-by-Step Solution

1
Assess roadway conditions and left-lane availability.
Oncoming traffic prevents changing lanes to create a buffer space.
Move-Over rules specify secondary required actions when lane changes are unsafe or blocked.
2
Apply the mandatory alternative requirement under Move-Over statutes.
The vehicle must slow down to a safe, reduced speed (typically 20 mph below the posted limit).
Slowing down provides a safety cushion for roadside workers and emergency responders when physical distance cannot be created.
