When the road turns slick or a part fails, your first instinct — slamming the brakes or jerking the wheel — is usually wrong. These are the handbook's exact responses.

Know the rule

On slippery roads, slow down, keep a safe distance and don't use cruise control. If you skid, stay calm and don't slam on the brakes; take your foot off the accelerator and brake until you can turn in the direction you want.

Handbook p. 85 ↗

Know the rule

With anti-lock brakes (ABS), don't pump them. Press down on the pedal and keep steering until you regain control. Check your owner's manual if you're unsure whether you have ABS.

Handbook p. 86 ↗

Know the rule

In thunderstorms or fog, slow down, increase following distance and be ready to stop. Use low-beam headlights when you can't see more than 500 feet or it's raining, snowing, sleeting or hailing. If you can't see a safe distance, pull off the road and wait.

Hydroplaning

At higher speeds water collects under the tires and lifts them off the road, so they lose all contact — you can't brake, accelerate or steer.

Handbook p. 86 ↗

Hydroplaning facts

  • At 35 mph or less, most tires wipe water away and keep contact
  • In heavy rain, standard cars may start hydroplaning at 35 mph
  • It can happen at any speed if the water is deeper than your tire tread
  • If it starts, take your foot off the gas pedal
  • Prevent it with good, deep-tread tires and slower speeds on wet roads
Handbook p. 86 ↗

Know the rule

On narrow roads where brush or trees block your view of a curve, you can use your horn to warn others. Don't coast down steep hills in neutral, and check your speedometer often — speed builds even off the gas.

Handbook p. 86 ↗

Know the rule

Blowout (you may hear thumping or feel the wheel pull first): hold the wheel tightly, steer straight and slowly ease off the accelerator. Don't brake until the vehicle is under control; then pull completely off the road.

Handbook p. 86 ↗

Know the rule

Steering failure: ease up on the accelerator and brake only if needed to avoid a crash — gently. Sudden braking or shifting can throw the vehicle off balance.

Handbook p. 87 ↗

Know the rule

Brake failure: a pedal that sinks slowly is a warning sign. If it drops to the floor, pump it; if that fails, slowly apply the parking brake (it works only the rear brakes). Downshift to lower gears until you can pull over.

Handbook p. 87 ↗

Know the rule

If your wheels drift onto the shoulder, don't swerve back. Stay on the shoulder, slowly release the gas, and after slowing, turn back onto the pavement, then speed up.

Handbook p. 87 ↗

Know the rule

If a vehicle comes at you in your lane, move right — never left. If it keeps coming, steer off the road to the right. Horn and headlight flashes may wake a sleepy or distracted driver.

Handbook p. 87 ↗

Know the rule

If a driver passing you on a two-lane road can't finish: slow down if they're nearly back in, speed up if they must drop back, and if a crash seems likely, move onto a wide right shoulder to let them into your lane.

Handbook p. 87 ↗

Put it into practice

Driving 60 mph in heavy rain, your steering suddenly feels light as the tires hydroplane. Take your foot off the gas — don't brake or turn hard — and let the car slow until the tires grip again.

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 vehicle begins to skid, what should you do first?
  1. Slam on the brakes immediately
  2. Turn the wheel sharply away from the skid
  3. Take your foot off the accelerator
  4. Shift into a higher gear

Answer: Take your foot off the accelerator

Easing off the accelerator, rather than braking hard, is the correct first response to a skid.

Handbook p. 85 ↗
If your vehicle has anti-lock brakes (ABS), how should you use them in an emergency stop?
  1. Pump the brakes rapidly, as with regular brakes
  2. Release the brake completely and coast to a stop
  3. Apply the parking brake instead
  4. Press down and keep steering; don't pump

Answer: Press down and keep steering; don't pump

ABS-equipped vehicles should have the brake pedal pressed firmly and held, not pumped.

Handbook p. 86 ↗
If your vehicle begins to hydroplane, what should you do?
  1. Brake hard to regain traction immediately
  2. Accelerate to push through the water
  3. Take your foot off the gas pedal
  4. Turn the wheel sharply to find grip

Answer: Take your foot off the gas pedal

Easing off the gas is the correct response to hydroplaning, since braking or turning sharply can cause loss of control.

Handbook p. 86 ↗
If you experience a tire blowout, what should you do first?
  1. Grip the wheel and steer straight
  2. Brake hard right away
  3. Steer sharply to the shoulder
  4. Shift into neutral at once

Answer: Grip the wheel and steer straight

Steering straight while holding the wheel firmly is the first step in handling a blowout safely.

Handbook p. 86 ↗
If your brake pedal suddenly sinks to the floor, what should you try first?
  1. Immediately apply the emergency brake at full force
  2. Shift into neutral and coast
  3. Turn off the ignition immediately
  4. Pump the pedal to try to build pressure

Answer: Pump the pedal to try to build pressure

Pumping the brake pedal is the first response to try to rebuild hydraulic pressure.

Handbook p. 87 ↗
If your wheels drift onto the shoulder, what should you do?
  1. Swerve right back onto the pavement
  2. Stay on the shoulder, slow down, then return
  3. Brake hard while on the shoulder
  4. Speed up to rejoin traffic

Answer: Stay on the shoulder, slow down, then return

You should stay on the shoulder and slow down before carefully steering back onto the road.
