The Institute of Advanced Motorists (IAM) is warning that despite 50 years of seat belt laws, far too many drivers and passengers are still putting themselves and others in great danger by not wearing seat belts. The first seat belt law came into force in January 1965, which saw all new cars in the UK required to have seat belt anchorage points on the outer front seats – and paved the way for far-reaching compulsory seat belt wearing laws in the decades after.
