Safety belts greatly reduce your chance of injury or death in a collision. They keep you from being thrown from the vehicle and help the driver keep control. Air bags add protection only when belts are worn.

Know the rule

Always fasten your safety belt, and make sure every passenger is using a safety belt or child restraint.

Handbook p. 48 ↗

Primary safety belt law

SC's law letting an officer stop a driver just for having a clear, unobstructed view of a driver or occupant not wearing a belt or not in a child restraint.

Handbook p. 49 ↗

Wear the belt correctly:

  • Shoulder harness across your shoulder and chest with minimal, if any, slack
  • Never under your arm or behind your back; that can cause serious internal injuries
  • Lap belt snug and low across your hips after fastening
  • A loose or high lap belt can let you slide out in a crash, causing injury or death

Know the rule

Wear safety belts even if your vehicle has air bags.

Handbook p. 49 ↗

Air bags

Supplemental restraints designed to work best in combination with safety belts.

Handbook p. 49 ↗

Know the rule

Together, air bags and safety belts reduce the chance that your head and upper body strike the vehicle's interior.

Handbook p. 49 ↗

Know the rule

Belts position your body to get the most from the air bag and restrain you during a collision. Check your owner's manual for details on your air bags.

Handbook p. 50 ↗

Put it into practice

An officer sees your front-seat passenger riding with the shoulder belt tucked behind her back. Under SC's primary law you can be stopped for that alone, and she risks internal injuries in a crash. Wear it across the chest.
