The first compulsory seat belt law was put in place in 1970, in the state of Victoria, Australia, requiring their use by drivers and front-seat passengers. This legislation was enacted after trialing Hemco seatbelts, designed by Desmond Hemphill (1926–2001), in the front seats of police vehicles, lowering the incidence of officer injury and death. Mandatory seatbelt laws in the United States began to be introduced in the 1980s and faced opposition, with some consumers going to court to challenge the laws. Some cut seatbelts out of their cars.

Content:  In Australia, after the introduction of mandatory front outboard mounting points in 1964, the use of seat belts by all vehicle passengers was made compulsory in the states of Victoria and South Australia in 1970 and 1971, respectively. By 1973, the use of fitted seat belts by vehicle occupants was made compulsory for the rest of Australia and some other countries during the 1970s and 1980s. The subsequent dramatic decline in road deaths is generally because of seat belt laws and subsequent road safety campaigns. Seat belts are not required for bus occupants unless fitted, reversing drivers, and those driving some slow-moving vehicles. The laws for these differ depending on the state or territory with jurisdiction.
Title: Seat belt legislation
Content:  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. Rear seat belts were compulsory equipment from 1986 and became compulsory for them to be worn in 1991. However, it has never been a legal requirement for cars registered before those dates to be fitted with seat belts. In one such attempt in 1979 similar claims for potential lives and injuries saved were advanced. William Rodgers, then Secretary of State for Transport in the Callaghan Labour Government (1976&ndash;1979), stated: "On the best available evidence of accidents in this country - evidence which has not been seriously contested - compulsion could save up to 1000 lives and 10,000 injuries a year."

Content:  (who was also the president of the Royal Society for the Prevention of Accidents) was finally successful, initially by proposing a private member's bill, and then by adding it as an amendment to the Transport Bill in the House of Lords. The House of Commons voted to accept the amendment on 28 July 1981. The act included clauses for: Following the three-year trial the compulsory wearing of seat belts was made permanent when both Houses of Parliament voted 'overwhelmingly' to retain the requirement. Legislation was subsequently introduced for the compulsory fitting of seat belts to the rear of cars (1987), for children to wear seat belts in the back (1989), and then adults(1991). Seat belts were required for minibuses and coaches carrying school children (1996) and for all coaches (2001).
Title: Highway Traffic Act (Ontario)
Content:  The Highway Traffic Act (HTA) (the Act) is legislation in Ontario, Canada, which regulates the licensing of vehicles, classification of traffic offences, administration of loads, classification of vehicles and other transport-related issues. First introduced in 1923 to deal with increasing accidents during the early years of motoring in Ontario, and replacing earlier legislation such as the Highway Travel Act, there have been amendments due to changes to driving conditions and new transportation trends. For example, in 2009, the Act was revised to ban the use of cell phones while driving. Offences under the Highway Traffic Act are the most commonly tried in Provincial Offences court. Over 1.3 million offences are tried each year under the Act, with the most common charges being speeding (559,013 occurrences, s. 128 - Speeding), running a red light (127,836 occurrences, s. 144 - Red light - proceed before green), driving whilst disqualified (117,470 counts, s. 7 - Drive motor vehicle, no currently validated permit), fail to stop (51,263 counts, s. 136 - Disobey stop sign - fail to stop) and telephoning whilst driving (51,210 counts, s. 78.1 - Drive - hand-held communication device).
