One rule applies to every emergency: THINK BEFORE YOU ACT. An instinctive move, like slamming on the brakes in a skid, is often the wrong one. These are the handbook's suggestions for when something on the car fails.

Know the rule

Blowout: hold the wheel tightly, steer straight and ease up on the accelerator. Don't brake until the vehicle is under control.

Handbook p. 75 ↗

Know the rule

A thumping sound from a bulge in the tire can warn of a blowout. A tire losing air fast pulls the car to the side. Under-inflation is one of the most common causes of blowouts.

Handbook p. 76 ↗

Know the rule

Losing a wheel is handled like a blowout: hold tightly, steer straight, ease off the gas, and don't brake until the car has slowed and is under control.

Handbook p. 76 ↗

Know the rule

Steering failure: ease up on the accelerator but don't brake or shift gears, which may throw the car out of control. As it slows, you may brake very gently.

Handbook p. 76 ↗

Brake failure (pedal sinks to the floor):

  • Pump the pedal to build up pressure
  • If that fails, apply the emergency or parking brake gently so you don't lock the wheels and skid
  • Shift to a lower gear so the engine slows you
  • Or turn off the engine, leaving the car in gear; you'll lose power steering and brakes
Handbook p. 76 ↗

Know the rule

A spongy pedal that slowly keeps sinking is the usual advance warning of brake failure.

Handbook p. 76 ↗

Know the rule

Stuck accelerator: hook your toe under the pedal and try to raise it. If that fails, turn off the engine to slow down; power steering and brakes will stop assisting.

Handbook p. 77 ↗

Know the rule

Headlight failure: try the parking lights and turn signals. On a dark, deserted road with no lights at all, slow down, stay on the pavement, then move onto the shoulder once slow enough.

Handbook p. 77 ↗

Know the rule

Wiper failure in blinding rain or snow: slow down, roll down the side window and put your head out to see, then get off the road. Do the same if your hood flies open.

Handbook p. 77 ↗

Put it into practice

Your brake pedal suddenly goes to the floor on a downhill street. Pump it to rebuild pressure. If that doesn't work, pull the parking brake gently so the wheels don't lock, and shift into a lower gear to let the engine slow you.

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 your car experiences a tire blowout, what should you do?
  1. Swerve quickly to the shoulder
  2. Hold the wheel tightly, steer straight, and ease off the accelerator
  3. Accelerate to maintain control
  4. Brake hard immediately

Answer: Hold the wheel tightly, steer straight, and ease off the accelerator

During a blowout, hold the wheel tightly, steer straight, and ease off the accelerator; don't brake until under control.

Handbook p. 75 ↗
If your brake pedal suddenly sinks to the floor, what should you try first?
  1. Apply the parking brake hard
  2. Shift into neutral and coast
  3. Pump the pedal to build pressure
  4. Turn off the engine immediately

Answer: Pump the pedal to build pressure

If the brake pedal sinks to the floor, try pumping it to build pressure before resorting to the parking brake.

Handbook p. 76 ↗
If pumping the brakes doesn't work, what should you use, and how?
  1. Parking brake, pulled on hard
  2. Shift into reverse
  3. Shift into neutral and coast
  4. Parking brake, applied gently

Answer: Parking brake, applied gently

If pumping fails, use the parking brake gently so you don't lock the wheels and cause a skid.

Handbook p. 76 ↗
If your steering suddenly fails, what should you avoid doing?
  1. Braking suddenly or shifting gears
  2. Holding the wheel
  3. Easing off the accelerator
  4. Letting the car slow down naturally

Answer: Braking suddenly or shifting gears

With steering failure, avoid sudden braking or shifting, which could throw the vehicle further off balance.

Handbook p. 76 ↗
If your headlights fail on a dark, deserted highway, you should try your parking lights or turn signals to help guide you off the road.
  1. True
  2. False

Answer: True

The handbook suggests using parking lights or directional signals if headlights suddenly fail, to help guide you off the road.
