Even a well-maintained car can fail. The key is not to panic and to know the one or two moves for each kind of failure, then get safely off the roadway and call for help.

Know the rule

Brake failure (conventional brakes): shift to a lower gear and pump the brake pedal fast and hard several times.

Know the rule

If pumping doesn't work, use the parking brake while holding the release, so you can let up if the rear wheels lock. In low gear, find a safe place off the road and call for help.

Know the rule

Flat tire or blowout: hold the wheel firmly and keep the car straight while slowing gradually. Take your foot off the gas but don't brake; coast to a stop off the road.

Handbook p. 109 ↗

Know the rule

Power steering failure: when the engine dies, steering fails. Keep a firm grip; you'll need extra hand power to steer. Stop in a safe area off the road.

Know the rule

Headlight failure: stop safely off the road. Try the headlight or dimmer switch; if that fails, use parking lights, flashers or turn signals and call for help.

Know the rule

Stuck gas pedal: keep your eyes on the road and quickly shift to neutral. Steer to a safe area, turn off the engine and call for help.

Know the rule

Hood flies up: slow down immediately. Look under the hood or out the side window, use the center line or lane markings as a guide, and pull off as soon as possible.

Put it into practice

Your accelerator sticks as you approach a red light. Keep looking ahead, shift into neutral right away, steer onto the shoulder, and turn off the engine once you're safely stopped.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

If a motorist experiences a tire blowout, what should they do?
  1. Grip the wheel, ease off the gas, don't brake
  2. Brake hard immediately
  3. Accelerate to maintain control
  4. Grip the wheel firmly and brake hard to stop quickly

Answer: Grip the wheel, ease off the gas, don't brake

With a blowout, the motorist should hold the wheel firmly, remove their foot from the gas, and not use the brakes, letting the vehicle coast to a stop.

Handbook p. 109 ↗
If a vehicle's brakes suddenly fail (non-ABS), what is the first thing a motorist should try?
  1. Turn off the engine immediately
  2. Downshift and pump the brake fast and hard
  3. Shift into neutral
  4. Pull the emergency brake abruptly at full force

Answer: Downshift and pump the brake fast and hard

With sudden brake failure, a motorist should shift to a lower gear and pump the brake pedal fast and hard several times to build pressure.

Handbook p. 109 ↗
What should a motorist do if their vehicle's headlights suddenly fail while driving?
  1. Continue driving using only the high beams
  2. Keep driving slowly with flashers on
  3. Rely on other vehicles' headlights to see
  4. Stop safely in a spot off the roadway

Answer: Stop safely in a spot off the roadway

If headlights suddenly fail, a motorist should safely stop the vehicle off the roadway and try the switches, then call for help if needed.

Handbook p. 109 ↗
If a vehicle's hood suddenly flies up while driving, what is a recommended technique to keep the vehicle under control?
  1. Guide by the lane lines and pull over
  2. Brake hard and stop in the lane
  3. Swerve right onto the shoulder at once
  4. Keep driving to the next exit

Answer: Guide by the lane lines and pull over

If the hood flies up, using the center line or lane markings as a guide helps the motorist safely pull off the roadway.

Handbook p. 110 ↗
If a vehicle's gas pedal sticks, a motorist should keep their eyes on the road and quickly shift into neutral.
  1. True
  2. False

Answer: True

If a gas pedal sticks, the motorist should keep watching the road while quickly shifting to neutral.

Handbook p. 110 ↗
If the engine dies while you are driving, the power steering keeps working normally.
  1. True
  2. False

Answer: False

When an engine dies, the steering fails; keep a firm grip because extra hand power is needed to turn.
