Seat belt legislation requires the fitting of seat belts to motor vehicles and the wearing of seat belts by motor vehicle occupants to be mandatory. Laws requiring the fitting of seat belts to cars have in some cases been followed by laws mandating their use, with the effect that thousands of deaths on the road have been prevented.

In the UK, a requirement for anchorage points was introduced in 1965, followed by the requirement in 1968 to fit three-point belts in the front outboard positions on all new cars and all existing cars back to 1965. Successive UK governments proposed, but failed to deliver, seat belt legislation throughout the 1970s. Front seat belts were compulsory equipment on all new cars registered in the UK from 1968, although it did not become compulsory for them to be worn until 1983.
