Difficulty: Very hardStuck Gas Pedal and Power Steering Failure

You are driving at highway speed when your accelerator pedal unexpectedly sticks in the fully open position. As you react, power steering assistance fails, making the wheel significantly heavier to turn. Arrange the critical emergency response procedures into the correct chronological order from first action to final action.

  1. 1Shift the transmission gear selector into Neutral (N) to disengage engine power from the drive wheels.
  2. 2Apply firm, steady pressure to the brake pedal without pumping to reduce vehicle speed.
  3. 3Scan traffic, signal, and use increased physical effort to steer smoothly toward a safe shoulder or emergency exit.
  4. 4Bring the vehicle to a complete stop entirely clear of moving traffic lanes.
  5. 5Turn the ignition key or start button to the OFF position, engage the parking brake, and activate hazard warning lights.

Answer

The correct emergency sequence is: 1) Shift transmission to Neutral (N), 2) Apply firm, steady brake pressure, 3) Signal and steer with extra effort toward the shoulder, 4) Bring the vehicle to a complete stop clear of traffic, and 5) Turn the ignition OFF, set the emergency brake, and switch on hazard lights.
The correct response order prioritizes neutralizing engine thrust first by shifting to Neutral. Next, speed is controlled with steady braking. Steering to safety follows using firm physical input despite power assist failure. Once completely stopped off the roadway, the engine ignition is safely turned off and parking safeguards are activated.

Step-by-Step Solution

1
Disengage engine torque from the drive wheels by shifting into Neutral (N).
The vehicle stops accelerating forward despite the throttle remaining open.
Shutting off engine propulsion instantly neutralizes the runaway speed hazard without locking the steering column.
2
Apply strong, steady pressure to the service brake pedal.
Vehicle speed decreases predictably.
Steady braking maximizes stopping force while preserving remaining power brake vacuum power.
3
Signal and firmly turn the steering wheel to guide the car to the shoulder.
The car transitions out of the active lane into a safe stopping zone.
Although power steering failed, mechanical linkage remains functional and allows manual control with increased physical exertion.
4
Completely stop the vehicle on the road shoulder.
The car is stationary and clear of high-speed traffic flow.
Stopping off the road ensures safety before performing vehicle system power-down.
5
Shut off the ignition switch, set the parking brake, and turn on emergency flasher lights.
The engine turns off and the parked vehicle is stabilized and clearly visible.
Ignition shutdown must only happen when stationary to avoid steering wheel lock-up while in motion.
