Difficulty: HardStuck Gas Pedal and Power Steering Failure

While merging onto an arterial road, a driver experiences a mechanical throttle malfunction where the accelerator pedal becomes stuck in the fully depressed position. To safely manage this emergency without risking a locked steering wheel or sudden loss of vehicle control, which sequence of actions should the driver execute?

  1. Shift the transmission into Neutral, apply smooth and steady pressure to the foot brake, activate the turn signal, and steer safely off the roadway.Answer
  2. B
    Turn the ignition key completely to the LOCK position to shut off the revving engine, pump the brake pedal forcefully, and glide onto the shoulder.
  3. C
    Apply maximum pressure to the brake pedal while keeping the vehicle in Drive, pull the emergency parking brake lever, and turn off the engine once stopped.
  4. D
    Pump the gas pedal repeatedly, shift into Park while moving to cut momentum, and coast to a complete stop in the lane of travel.

Answer

The correct response is to shift the transmission into Neutral, apply smooth and steady pressure to the foot brake, activate the turn signal, and steer safely off the roadway.
Shifting the transmission into Neutral is the critical first step because it immediately decouples engine torque from the drive wheels. This allows the driver to use the foot brake effectively to slow down while maintaining active power steering control. Once speed is reduced, the driver can safely signal and steer to the shoulder before turning off the engine.

Step-by-Step Solution

1
Disengage engine power from the drive wheels.
Shifting into Neutral prevents the racing engine from continuing to accelerate the vehicle.
Neutral allows engine RPMs to rise safely against the rev limiter without transferring torque to the tires.
2
Apply steady and firm pressure to the brake pedal.
The brakes can decelerate the vehicle efficiently without fighting engine torque.
Steady braking maintains vehicle stability and prevents wheel lockup.
3
Signal and steer to a safe location off the roadway.
The vehicle maintains power steering assistance while moving safely to the shoulder.
Keeping the engine running until the vehicle has stopped preserves power steering and power braking assistance.
4
Turn off the ignition once fully stopped in a safe area.
The engine stops revving safely after the vehicle is completely stationary.
Shutting off the engine after stopping eliminates all remaining risk.
