In the few seconds before a possible crash, try not to panic; reacting properly and quickly can avoid it or reduce the damage. Know how your brakes work, when to steer away, and how to brace if a hit is coming.

Four factors behind most U.S. collisions:

  • Equipment failure: brakes, unsafe tires, steering, suspension
  • Roadway design: traffic controls, surfaces, weather, hazards, traffic flow
  • Poor roadway maintenance: debris, potholes, construction
  • Driver behavior: speeding, tailgating, aggression, unsafe lane changes, not signaling or yielding
Handbook p. 120 ↗

Know the rule

In 95% of motor vehicle crashes, driver behavior combined with one of the other three factors.

Handbook p. 120 ↗

Know the rule

Put loose items in the trunk, and keep an accident kit in the glove compartment: paper, pen, insurance information, any medical information, and emergency supplies.

Emergency stop without ABS:

  • Pump the brake: push the pedal hard
  • As the car begins to skid, quickly let up
  • Quickly push down again, pumping until the car stops
Handbook p. 120 ↗

Know the rule

When you press hard, ABS pumps the brakes up to 30 times per second. ABS doesn't stop the car faster; it keeps you in control and stopping in a straight line so you can steer.

Handbook p. 120 ↗

Know the rule

An ABS light that comes on when you start the car and then dims means you have ABS. If it stays lit, the ABS isn't working correctly.

Handbook p. 120 ↗

Know the rule

If a crash looks likely, turn away even if it means leaving the road: drive, don't skid, off it. Hit something that gives, like brush, rather than something hard, and make it a glancing blow. Never cross into oncoming traffic.

Handbook p. 120 ↗

Know the rule

Sometimes speeding up quickly avoids a crash, such as when a car is about to hit you from the side or behind.

Handbook p. 120 ↗

Oncoming car in your lane:

  • Blow your horn and flash your lights, if there's time
  • Brake fast, but don't lock your wheels
  • If a crash is probable, steer off to the right shoulder or ditch, never into the left lane
Handbook p. 121 ↗

Someone passing you can't finish the pass:

  • Slow down and move as far right as you safely can
  • If they must drop back, speed up so they can move in behind you
  • If a crash is almost certain, move onto a safe right shoulder

Bracing for a crash

Bracing for a crash
About to be hit fromWhat to do
The rearBe ready to brake; brace; head back on headrest
The sideGrip the wheel tightly; be ready to steer
The front, beltedProtect your face with your arms and hands
The front, no shoulder strapThrow yourself across the seat
Handbook p. 121 ↗

Put it into practice

A pickup crosses the center line toward you on a two-lane road. Honk and flash your lights, brake hard without locking the wheels, and if it keeps coming, steer onto the right shoulder or into the ditch, never into its lane.

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.

How fast does an ABS system pump the brakes when engaged?
  1. Once per second
  2. 5 times per second
  3. Up to 30 times per second
  4. 100 times per second

Answer: Up to 30 times per second

ABS rapidly pumps the brakes, up to 30 times per second, faster than a person could manually.

Handbook p. 120 ↗
A car is coming toward you in your lane and a crash seems likely. Where should you steer?
  1. Straight ahead while braking hard
  2. Toward the center line
  3. To the right shoulder or ditch
  4. Into the left, oncoming lane

Answer: To the right shoulder or ditch

If a crash is probable, steer off the road to the right shoulder or ditch; do not drive into the left lane.

Handbook p. 121 ↗
Anti-lock brakes (ABS) are designed mainly to make your car stop in a shorter distance.
  1. True
  2. False

Answer: False

ABS does not stop the car faster; it lets you stop where you want by allowing you to steer while braking.

Handbook p. 120 ↗
In what percentage of crashes did driver behavior combine with one of the other factors?
  1. 25%
  2. 95%
  3. 50%
  4. 75%

Answer: 95%

In 95% of motor vehicle accidents some factor of driver behavior combined with one of the other three factors.

Handbook p. 120 ↗
You're about to be hit from the rear. What should you do?
  1. Brace, with your head against the headrest
  2. Turn the wheel sharply to one side
  3. Take your foot off the brake completely
  4. Throw yourself across the front seat

Answer: Brace, with your head against the headrest

Be ready to brake, brace yourself between the wheel and seat back, and press the back of your head against the head rest.
