Seat belts: the law

1. Overview

You must wear a seat belt if one is fitted in the seat you’re using - there are only a few exceptions.

You’re also only allowed 1 person in each seat fitted with a seat belt.

You can be fined up to £500 if you don’t wear a seat belt when you’re supposed to.

Children

You must make sure that any children in the vehicle you’re driving are:

  • in the correct car seat for their height or weight until they reach 135 centimetres tall or their 12th birthday, whichever is first
  • wearing a seat belt if they’re 12 or 13 years old, or younger and over 135cm tall

You can be fined up to £500 if a child under 14 isn’t in the correct car seat or wearing a seat belt while you’re driving.
