Car crashes are the number one killer of teenagers, and buckling up is the easiest way to avoid being a statistic. Seat belts are the single most effective way to prevent death and injury in a crash—and not wearing one breaks Iowa law.

Know the rule

Everyone should be properly buckled before the vehicle moves. Wear the lap belt snugly across your hips. If pregnant, wear it across the pelvis, as low under the abdomen as possible.

Handbook p. 34 ↗

Know the rule

Iowa requires all front-seat occupants to wear seat belts. The law also applies to back-seat passengers under age 18.

Handbook p. 34 ↗

Seat belt myths vs. facts:

  • Thrown clear? Your chances of not being killed are much better if you stay inside the car
  • 'It only affects me'? Unbelted, you can become a projectile and injure or kill others in the car
  • 'Only for long trips'? Over half of traffic deaths happen within 25 miles of home
  • 'Belts trap you'? Unbuckling takes under a second, and a belt may keep you conscious to escape

25 miles

Over half of all traffic deaths happen within this distance of home

Handbook p. 35 ↗

Know the rule

Many traffic deaths occur on roads with speed limits of less than 45 mph.

Handbook p. 35 ↗

Know the rule

Even alone in the car, being improperly buckled means a sudden swerve or stop can force you from the driver's seat and likely cause a crash.

Handbook p. 35 ↗
1,000 lb

Force with which a 20-pound loose object hits at 55 mph

Handbook p. 35 ↗

Know the rule

Secure loose objects, and make sure nothing on the floor can roll under the brake pedal and keep you from braking.

Handbook p. 35 ↗

Put it into practice

You're driving your 16-year-old brother, who sits in back, and your 5-year-old cousin. Your brother must buckle up even in back; your cousin must ride in a safety or booster seat—a seat belt alone isn't enough under age 6.
