Crash forces are far bigger than most people imagine. The handbook's safety belt facts explain why a belt, and the right car seat for a child, is your best protection, including against a drunk driver.

30 times

In a 30-mph head-on collision (about 20 G's), objects and passengers can be thrown forward with force equal to 30 times their own weight

Handbook p. 26 ↗
450 pounds

What a 15-pound infant suddenly "weighs" in a 30-mph collision, so holding a child in your arms won't protect them

Handbook p. 26 ↗
Almost 25 times

How much greater your chance of being killed is if you're thrown from the car

Handbook p. 25 ↗
More than 80%

Share of collisions that occur at speeds under 40 mph; three of four fatal collisions occur within 25 miles of home

Handbook p. 25 ↗
Less than 1/2 of 1%

Share of collisions involving fire or submersion

Handbook p. 25 ↗

Know the rule

In a burning or submerged vehicle your chance of survival is far greater with a belt on, because you're more likely to stay conscious and able to escape.

Handbook p. 25 ↗

Know the rule

A lap belt alone won't keep your head and chest from striking the wheel, dashboard and windshield. A lap and shoulder belt give the best possible protection.

Handbook p. 25 ↗

Know the rule

An unrestrained adult can crush a child held in their arms during a collision.

Handbook p. 26 ↗

Know the rule

A loose belt doesn't mean it's broken. Belts made after 1974 use an inertia reel that locks when the car slows down too quickly.

Handbook p. 26 ↗

Know the rule

A lap belt may put too much pressure on a small child's hips and abdomen. Child car seats spread crash forces over a large area of the body.

Handbook p. 26 ↗

Know the rule

Only an approved, dynamically crash-tested child car seat gives adequate protection; all such seats conform to Federal Standard 213-80.

Handbook p. 26 ↗

Know the rule

Motor vehicle crashes are a significant killer and crippler of children under five. A child in a car seat is also better behaved and less likely to distract the driver.

Handbook p. 25 ↗

Put it into practice

A parent says, "It's a short trip across town, I'll just hold the baby." Most crashes happen close to home and under 40 mph, and at 30 mph a 15-pound infant becomes 450 pounds. The baby belongs in a car seat.

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.

More than what percentage of all collisions occur at speeds less than 40 mph, according to the handbook?
  1. 50 percent
  2. 80 percent
  3. 95 percent
  4. 65 percent

Answer: 80 percent

The handbook states more than 80% of collisions occur below 40 mph.

Handbook p. 25 ↗
About how much greater are your chances of being killed if thrown from the vehicle in a crash?
  1. About 2 times greater
  2. About 5 times greater
  3. About 25 times greater
  4. About 50 times greater

Answer: About 25 times greater

Being thrown from a vehicle raises the chance of death by almost 25 times.

Handbook p. 25 ↗
A 15-pound infant held in an adult's arms during a 30-mph crash will suddenly exert a force equivalent to about how much weight?
  1. 150 pounds
  2. 450 pounds
  3. 1,000 pounds
  4. 75 pounds

Answer: 450 pounds

Crash forces can make a 15-pound infant effectively weigh 450 pounds.

Handbook p. 26 ↗
Loose safety belts always mean the belt system is broken or inoperative.
  1. True
  2. False

Answer: False

Loose belts don't mean they're broken; inertia-reel belts are designed to lock only when the car slows quickly.

Handbook p. 26 ↗
A lap belt alone, without a shoulder belt, offers the same crash protection as a lap-and-shoulder belt.
  1. True
  2. False

Answer: False

A lap belt helps but does not prevent injury from striking the head and chest; a lap-and-shoulder belt offers the best protection.
