While driving in the right-hand lane of a multi-lane highway through an active construction area with a posted work zone speed limit of 45 mph, a motorist observes a stationary highway maintenance truck displaying flashing amber and blue emergency lights parked on the right shoulder. If traffic in the adjacent left lane is too dense to safely merge, what action is the motorist legally required to take?

  1. Reduce speed significantly below the posted 45 mph work zone limit while remaining in the right lane and proceeding with caution.Answer
  2. B
    Maintain the posted 45 mph speed limit without slowing, because Move-Over regulations apply exclusively to law enforcement and fire vehicles.
  3. C
    Bring the vehicle to a complete stop within the active travel lane until work zone crew members give hand signals to proceed.
  4. D
    Accelerate above the work zone limit to clear the area next to the parked maintenance vehicle as rapidly as possible.

Answer

The driver must slow down significantly below the posted work zone speed limit while remaining in the current lane if merging into an adjacent lane cannot be performed safely.
Under standard Move-Over laws and work zone regulations, motorists approaching a stationary emergency, maintenance, or utility vehicle displaying activated flashing lights must clear the lane adjacent to the vehicle if safe to do so. When heavy traffic or road conditions make changing lanes unsafe, the driver is legally required to reduce speed significantly below the posted limit and proceed with extreme caution.

Step-by-Step Solution

1
Identify the legal obligation under state Move-Over and work zone safety laws when approaching stationary emergency or service vehicles displaying active flashing lights.
The law mandates either vacating the adjacent lane (moving over) or reducing speed if moving over is unsafe.
Roadside workers and emergency responders require a safety buffer from passing high-speed traffic.
2
Evaluate the traffic scenario conditions given in the stem.
Heavy traffic prevents a safe lane change into the adjacent left lane.
Drivers must never execute unsafe or forced lane changes into occupied traffic.
3
Determine the required secondary legal procedure when a lane change is impossible.
The driver must significantly reduce vehicle speed below the posted work zone speed limit and proceed with heightened caution.
Slowing down minimizes collision severity and allows adequate reaction time if workers step near the travel lane.
