Every driver eventually faces an emergency. You have three tools to avoid a crash — braking, steering and accelerating — and knowing which to use, and how, can prevent a serious outcome.

Know the rule

All drivers have the responsibility to prevent crashes.

Handbook p. 42 ↗

Know the rule

Braking: most drivers' first reaction is to stop. Most new vehicles have ABS (anti-lock braking system) to stop without skidding — see your owner's manual for how to brake with it.

Swerving

Quickly steering around a problem to avoid a crash.

Handbook p. 42 ↗

Know the rule

To swerve, grip the wheel with both hands and steer to avoid other traffic, then steer the opposite way to straighten out, regain control and start slowing.

Know the rule

Accelerating: speeding up may be necessary to avoid a crash, for example when another vehicle is about to hit you from behind or the side.

Handbook p. 42 ↗

Skids are caused by:

  • Traveling too fast for conditions
  • Stopping too suddenly
  • Tires that can no longer grip the road
Handbook p. 42 ↗

Know the rule

When you begin to skid, release pressure from the brake or accelerator and turn the wheel into the skid.

Handbook p. 42 ↗

Know the rule

When power outages leave a traffic signal dark, treat it as a four-way stop — unless a law enforcement officer is directing traffic. Proceed carefully; others may not stop.

Handbook p. 42 ↗

Know the rule

If your vehicle leaves the paved surface at an uneven drop-off, let off the accelerator, slow down gradually, and return to the pavement only when it's safe.

Put it into practice

Your right wheels drop off the pavement edge onto a lower shoulder. Don't jerk the wheel back. Ease off the gas, slow gradually, and steer back onto the pavement when it's safe.

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?
  1. Brake hard immediately
  2. Accelerate to straighten out
  3. Turn the wheel opposite the skid
  4. Ease off the brake or gas and steer in the direction of the skid

Answer: Ease off the brake or gas and steer in the direction of the skid

When skidding, release pressure from the brake or accelerator and turn the wheel into the skid.

Handbook p. 42 ↗
How should you treat an intersection with a dead traffic signal due to a power outage?
  1. As a four-way stop
  2. As a green light for all directions
  3. As a road closed to traffic
  4. As a yield sign only in one direction

Answer: As a four-way stop

By law, drivers must treat a non-working traffic signal as a four-way stop, except when an officer is directing traffic.

Handbook p. 42 ↗
If your vehicle's wheels drop off the edge of the pavement, what should you do?
  1. Brake hard immediately and jerk the wheel back onto the pavement
  2. Ease off the gas and slow before returning
  3. Accelerate to power back onto the road
  4. Continue at the same speed off the pavement

Answer: Ease off the gas and slow before returning

Let off the accelerator, slow down gradually, and return to the pavement only when safe.

Handbook p. 42 ↗
Why is accelerating sometimes the right response to avoid a crash?
  1. It always prevents a rear-end collision
  2. It's the default recommended response to every hazard
  3. It may prevent being hit from behind or the side
  4. It reduces your stopping distance

Answer: It may prevent being hit from behind or the side

Accelerating may be necessary to avoid a crash when another vehicle is about to hit you from behind or the side.

Handbook p. 42 ↗
You're driving and the traffic signal ahead is dark due to a power outage, but a police officer is directing traffic. What governs your actions?
  1. The four-way-stop rule regardless of the officer
  2. You must wait for the signal to restore power
  3. You should turn around and find another route
  4. The officer's directions

Answer: The officer's directions

The four-way-stop treatment for a dead signal applies except when a law enforcement officer is present to direct traffic.

Handbook p. 42 ↗
After steering around a problem to avoid a crash, you steer in the opposite direction to straighten out your vehicle.
  1. True
  2. False

Answer: True

When swerving, steer to avoid traffic, then steer in the opposite direction to straighten out, gain control, and start slowing.
