Difficulty: HardVehicle Emergencies and Equipment Failures

While driving on a multi-lane highway, your vehicle's accelerator pedal suddenly becomes stuck in the fully depressed position, and pulling up on the pedal with your toe fails to free it. Which of the following procedure sequences represents the safest immediate response to safely stop the vehicle?

  1. Shift the transmission into Neutral, apply steady and firm pressure to the brakes, signal and steer smoothly onto the shoulder, and turn off the engine only after reaching a complete stop.Answer
  2. B
    Turn the ignition key immediately to the Lock position to shut off the engine, then pull the parking brake rapidly while steering off the road.
  3. C
    Slam forcefully on the foot brake while keeping the vehicle in Drive, then steer rapidly back and forth across lanes to scrub off speed.
  4. D
    Shift the transmission directly into Park while moving to lock the drive wheels, then steer toward the road shoulder.

Answer

Shift the transmission into Neutral, apply steady and firm pressure to the brakes, signal and steer smoothly onto the shoulder, and turn off the engine only after reaching a complete stop.
The correct response requires shifting to Neutral to immediately stop acceleration without disabling power steering or power braking. The driver should then brake smoothly, guide the vehicle off the road, and turn off the engine after stopping completely.

Step-by-Step Solution

1
Disengage engine drive power from the wheels.
Shifting into Neutral stops acceleration immediately while leaving power steering and power braking fully operational.
This allows the driver to control vehicle velocity without fighting engine torque.
2
Apply steady braking pressure and scan for a safe pull-off area.
The vehicle slows down predictably without locking the wheels.
Steady braking reduces speed safely while steering control remains active.
3
Signal, pull off the roadway, and turn off the ignition.
The vehicle is safely removed from moving traffic and brought to a complete stop before shutting off engine ignition.
Shutting off the engine before stopping removes power assistance, so waiting until fully stopped ensures maximum vehicle control throughout the maneuver.
