Question

Difficulty: MediumEmergency Vehicles and Move-Over Laws

While driving in the lane adjacent to the shoulder on a four-lane divided highway, you notice a utility service vehicle stopped on the right shoulder with active flashing emergency lights. Heavy traffic prevents you from safely merging into the left lane. What action are you legally required to take under Move-Over laws?

  1. A
    Maintain your normal speed and continue straight ahead because changing lanes is unsafe.
  2. Slow down significantly below the posted speed limit and proceed past the vehicle with caution.Answer
  3. C
    Come to a complete stop in your active travel lane until the shoulder vehicle finishes its operation.
  4. D
    Accelerate quickly past the stopped vehicle to clear the immediate hazard zone faster.

Answer

Reduce your vehicle speed significantly below the posted limit and proceed with heightened caution when changing lanes is unsafe.
When approaching a stationary emergency, maintenance, or service vehicle displaying flashing lights on the shoulder, drivers must move over to an adjacent lane if safe. If traffic or road conditions prevent changing lanes, drivers are legally mandated to reduce their speed significantly below the posted limit and pass with caution.

Step-by-Step Solution

1
Assess traffic condition and feasibility of changing lanes.
Heavy adjacent traffic prevents safely moving into the open left lane.
Move-Over laws require moving over a lane as the primary safe action if traffic permits.
2
Apply the secondary mandate of the Move-Over law when a lane change is unsafe.
Driver reduces speed significantly below the posted speed limit while remaining in the current lane.
Slowing down minimizes risks to personnel working on the shoulder when extra lateral space cannot be created.
