Seat Belt and Child Restraint Laws

Seat belts save lives – period. California law requires that all occupants wear seat belts, and that children are secured in appropriate safety seats. Here are the specifics:

Driver and Passengers

You, as the driver, can be cited if you or any passenger in your vehicle is not wearing a seat belt. This applies to both front and back seat passengers. It’s a primary law, meaning an officer can pull you over just for a seat belt violation.
Always buckle up before you drive.
Make it a habit: “Engine on, belt on.”

Proper Wear

  • The shoulder belt should go over your shoulder, not under your arm or behind your back.
  • The lap belt should rest low over your hips, not over your stomach.
  • Adjust belts so they are snug.

Seat belts are designed to spread crash forces over the stronger parts of your body. Misuse reduces effectiveness and can cause injury.

Airbags & Seat Belts

  • Airbags are supplemental restraints – they do not replace seat belts.
  • You must wear a belt even if your car has airbags.
  • Maintain at least 10 inches between your chest and the airbag (steering wheel or dashboard).

Airbags can cause injury if you’re unbelted and thrown into them during a crash.

Passenger Responsibility

  • If your passenger is 16 or older and not belted, they can receive a ticket.
  • If they are under 16, you (the driver) are responsible and will receive the citation.
