Rear Seatbelt Laws: A Historical Safety Perspective

Seat belt laws have been a topic of debate and discussion for decades, with the first federal law mandating seat belts in all vehicles (except buses) coming into effect on January 1, 1968. This law, Title 49 of the United States Code, Chapter 301, Motor Safety Standard, required all vehicles to be fitted with seat belts in all designated seating positions. However, the use of seat belts was voluntary until New York became the first state to mandate their use on December 1, 1984. Since then, most US states have implemented primary or secondary seat belt laws, with varying levels of enforcement. While seat belt laws have faced resistance and criticism, they have undoubtedly played a crucial role in reducing road fatalities and increasing road safety.

Seat belt legislation varies by country

United States

Seat belt legislation in the United States varies by state. In 1961, Wisconsin became the first state to require seat belts to be installed in the front seats of cars. Seat belts have been mandatory in all new cars since 1968. However, the use of seat belts was voluntary until 1984, when New York became the first state to mandate their use. As of 2007, 25 states and the District of Columbia had primary seat belt laws, allowing police officers to stop and ticket a driver solely for not wearing a seat belt. 24 states had secondary seat belt laws, meaning that a driver could only be ticketed for not wearing a seat belt if they were pulled over for another violation. New Hampshire is the only state with no law requiring adults to wear seat belts.

Canada

All provinces in Canada have primary enforcement seat belt laws. Ontario was the first province to pass a law requiring vehicle occupants to wear seat belts in 1976.

United Kingdom

In the UK, seat belts have been mandatory in all new cars since 1968, but it was not compulsory to wear them until 1983. Rear seat belts became compulsory in 1986 and it became compulsory to wear them in 1991. Children must use an appropriate child seat in addition to a standard seat belt unless they are 12 years old or taller than 135 cm.

Australia

After the introduction of mandatory front outboard mounting points in 1964, the use of seat belts was made compulsory in the states of Victoria and South Australia in 1970 and 1971, respectively. By 1973, the use of seat belts was made compulsory for the rest of Australia.

India

All cars manufactured after March 25, 1994, in India are equipped with front seat belts, and this rule was extended to rear seats in 2002. However, enforcement of seat belt usage is weak in most parts of the country.

Seat belt laws in the United States vary by state

The effectiveness of seat belt laws in reducing road deaths and injuries has been well-established, with primary enforcement laws (where police can pull over a driver solely for not wearing a seat belt) being more effective than secondary enforcement laws (where a driver can only be punished for a seat belt violation if they are pulled over for another reason). As of 2022, 35 states and the District of Columbia have primary enforcement laws, while 15 states have secondary enforcement laws. New Hampshire is the only state with no law requiring adults to wear seat belts.

The variation in seat belt laws by state can be attributed to the ideological and practical concerns of different state legislatures. Some legislators were reluctant to enact primary enforcement laws due to concerns about potential police harassment of minorities, while others viewed mandatory seat belt laws as an infringement of individual liberty and a symbol of "mass hysteria." Despite these objections, seat belt laws have become increasingly common, with 29 states adopting mandatory seat belt laws between 1984 and 1987.

Publicized enforcement campaigns, such as "Click It or Ticket," have also played a significant role in increasing seat belt use. Additionally, higher fines for seat belt violations have been associated with higher rates of compliance. The effectiveness of seat belt laws is further supported by studies showing that switching from a secondary to a primary enforcement law reduces passenger vehicle driver deaths by 7%.

While seat belt laws have faced opposition, they have undoubtedly saved thousands of lives and are considered one of the most cost-effective public health inventions.

Primary vs secondary enforcement

Seat belt laws in the United States are divided into two categories: primary and secondary enforcement.

Primary Enforcement

Primary enforcement laws allow law enforcement officers to stop and ticket a driver or passenger for not wearing a seat belt, without any other traffic offence taking place. In other words, police officers can pull over drivers and issue tickets just because they or their passengers aren't wearing seat belts. As of August 2020, 34 states and the District of Columbia had primary enforcement laws for seat belts.

Secondary Enforcement

Secondary enforcement laws state that law enforcement officers may issue a ticket for not wearing a seat belt only when there is another citable traffic infraction. In other words, secondary enforcement laws only allow police officers to issue tickets for seat belt violations if drivers have been pulled over for some other offence. As of August 2020, 15 states had secondary enforcement laws for seat belts.

Effectiveness

Seat belt use is consistently higher in states with primary enforcement laws than in states with secondary enforcement laws. A study of 2011-2016 data found that self-reported seat belt use was higher in states with primary enforcement laws (89%) than in states with secondary enforcement laws (82%). Primary enforcement laws are more effective at getting people to wear seat belts, although the difference in belt use rates between states with secondary and primary laws has shrunk in recent years.

Costs and Implementation

Some costs may be incurred for publicity and enforcement after the enactment of legislation upgrading a state's seat belt law from secondary to primary enforcement. However, publicity costs should be low as the media is likely to cover the law change extensively. Primary seat belt enforcement can be implemented quickly after the change in enforcement is enacted, unless the update calls for a delayed effective date to allow time for transition.

The effectiveness of seat belts

Seat belts are highly effective in reducing the risk of injury and death in the event of a car crash. Studies have shown that wearing a seat belt can reduce the risk of fatal injury by up to 48% for drivers and front-seat passengers, and up to 60% for light truck occupants. The National Highway Traffic Safety Administration (NHTSA) estimates that in 2017, seat belts saved approximately 15,000 lives in the United States alone. This number could have been even higher if everyone had buckled up, as it is estimated that an additional 2,500 lives could have been saved if all vehicle occupants had been wearing seat belts.

In addition to saving lives, seat belts also provide economic benefits. The Centers for Disease Control and Prevention (CDC) found that in 2010, non-fatal injuries to motor vehicle occupants cost the United States $48 billion in medical expenses and lost work. By reducing the severity of injuries, seat belt use can help reduce these economic costs.

While seat belts are highly effective in reducing injuries and fatalities, it is important to wear them correctly. Improperly wearing a seat belt, such as placing the strap below the arm, can put individuals at risk in a crash. It is also important to ensure that seat belts fit properly and are adjusted correctly for each occupant.

Seat belt legislation has played a crucial role in increasing seat belt use and reducing road fatalities. In the United States, the first federal law mandating the installation of seat belts in all new cars was introduced in 1968. However, it was not until the 1980s that states began to pass laws requiring the use of seat belts. New York became the first state to mandate seat belt use in 1984, and since then, most states have followed suit. As of 2023, the national seat belt use rate in the United States was at 91.9%.

Opposition to seat belt legislation

The implementation of seat belt legislation has faced opposition from various groups and individuals, with several arguments put forward against it. One of the most common grounds for opposition is the belief that laws requiring the wearing of seat belts infringe upon individual liberty and freedom of choice. This ideological objection was particularly prominent in the 1980s, with some people even comparing seat belt legislation to the authoritarianism of Hitler.

Another argument against seat belt laws is that they are unnecessary, with opponents claiming that the official estimates of lives saved by seat belts are exaggerated or fail to consider the increased risks for other road users. This view was supported by a 1987 Chicago Tribune editorial, which stated: "In this country, saving freedom is more important than trying to regulate lives through legislation."

Some opponents of seat belt legislation also argue that the requirement to wear seat belts might give drivers a false sense of security, leading them to take fewer precautions and drive more dangerously. This theory, known as risk compensation or risk homeostasis, suggests that reducing the risk of death or injury from a car crash will encourage riskier driving behaviours.

In addition to these arguments, there have been practical objections to seat belt laws. For example, some people find seat belts uncomfortable or restrictive, particularly the early automatic safety belts. There were also concerns that automatic seat belts could trap passengers in a burning car, and that the mandatory installation of cheaper seat belts would hinder the development of airbags.
