Blowouts and mechanical failures can happen any time. Knowing the right first move — often the opposite of your instinct — keeps a failure from turning into a crash.

If a tire blows out:

  • Hold the steering wheel tightly and keep the vehicle going straight
  • Ease off the gas; do not apply the brakes
  • Let the vehicle slow until almost stopped, signal, pull off the road, then brake
Handbook p. 68 ↗

Know the rule

Reduce your chances of a blowout by checking tire pressure regularly.

Handbook p. 68 ↗

Know the rule

Vehicle fires usually start with a short circuit. Pull off quickly, shut off the ignition, get everyone away from the car and call 911.

Handbook p. 68 ↗

Know the rule

An ABC rated dry chemical extinguisher is best for vehicle fires. Never use water on burning gasoline — it spreads the flames. A heavy blanket, coat or sand can smother flames.

Handbook p. 68 ↗

If steam shows your engine is overheating:

  • Pull to the side of the road and turn off the engine immediately
  • Raise the hood, but do not open the radiator cap — escaping steam can cause severe burns
  • Add water only after the engine has cooled — never while it's hot
Handbook p. 68 ↗

Know the rule

Power steering failure (for example, the engine dies in a turn): grip the wheel firmly with both hands, finish the turn, move right and stop — push the brakes extra hard if you have power brakes.

Handbook p. 69 ↗

If your headlights fail:

  • Try the high beam/low beam switch
  • Turn the headlight switch on and off several times
  • If neither works, use parking lights, flashers or turn signals, pull off and stop
Handbook p. 69 ↗

Know the rule

Do not pump anti-lock brakes (ABS).

Handbook p. 69 ↗

Brake failure without ABS:

  • Pump the brakes rapidly to build pressure
  • If that fails, slowly apply the parking brake, holding the release in case the rear wheels lock
  • Shift to a lower gear and look for a safe place to stop
Handbook p. 69 ↗

Put it into practice

Your front tire blows at 65 mph and the car pulls hard. Grip the wheel, keep it straight and ease off the gas without braking. Once you've slowed to almost stopped, signal, pull off and brake.

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 you experience a tire blowout, what should you do with the gas and brake pedals initially?
  1. Pump the brakes rapidly right away
  2. Ease off the gas; don't brake
  3. Apply the brakes hard immediately
  4. Press the gas to maintain control

Answer: Ease off the gas; don't brake

Ease off the gas pedal and do not apply the brakes right away; let the vehicle slow naturally before braking.

Handbook p. 68 ↗
During a tire blowout, what should you do with the steering wheel?
  1. Hold it tightly and steer straight
  2. Let go briefly to avoid overcorrecting
  3. Turn sharply toward the shoulder immediately
  4. Turn sharply away from the blown tire

Answer: Hold it tightly and steer straight

Hold the steering wheel tightly and keep the vehicle going straight during a blowout.

Handbook p. 68 ↗
If your vehicle catches fire and gasoline is burning, what should you avoid using to put it out?
  1. A fire extinguisher
  2. A heavy blanket
  3. Sand
  4. Water

Answer: Water

Do not use water on a gasoline fire, as it will spread the flames; use an ABC extinguisher, blanket, coat, or sand.

Handbook p. 68 ↗
What type of fire extinguisher is recommended for vehicle fires?
  1. A water-based extinguisher
  2. A foam-only extinguisher
  3. An ABC dry chemical type
  4. A CO2-only extinguisher

Answer: An ABC dry chemical type

An ABC-rated dry chemical extinguisher is best for vehicle fires.

Handbook p. 68 ↗
If your engine overheats and steam appears, what should you NOT do?
  1. Raise the hood
  2. Open the radiator cap while the engine is hot
  3. Pull to the side of the road
  4. Turn off your engine

Answer: Open the radiator cap while the engine is hot

Never open the radiator cap while the engine is hot, since escaping steam can cause severe burns.

Handbook p. 68 ↗
If your headlights fail, trying the high beam/low beam switch may restore normal function.
  1. True
  2. False

Answer: True

Trying the high/low beam switch is a recommended first step for headlight failure.
