As we travel in cars, we put complete trust in the vehicle’s safety features, including airbags, helmets and seat belts. We rely on these measures to keep us safe and reduce the risk of accidents. However, the use of seat belts in cars is a mandatory discipline that has passed through various levels of evolution.

First mandatory seatbelt laws

The initial considerations of seat belt safety began in the mid-1950s. The Saab engineer recognized the vulnerability and safety limitations of cars at the time, and after several tests and examinations, he formulated the three-point seatbelt. This innovation provided an ultimate form of vehicle security and truly revolutionized passenger protection.

Several accidents and fatalities occurred due to the lack of seat belt usage, but the public was not immediately convinced to wear them. However, in 1966, with seatbelt laws making its way into the legislation, people began to understand that wearing seat belts would ultimately lead to reduced accidents and fatalities on the road.

The National Traffic and Motor Vehicle Safety Act

The National Traffic and Motor Vehicle Safety Act of 1966, advocated by President Lyndon Johnson, made the use of seat belts compulsory in all motor vehicles on public roads in the United States. This law required all vehicles manufactured in 1968 or later to be appropriately equipped with seat belts, which ultimately made them mandatory for all car journeys.

Moreover, the National Traffic and Motor Vehicle Safety Act established new safety standards for automobile manufacturers to abide by; this included the requirement of all new vehicles to have front-seat outboard lap belts, front-rear seat belt systems, energy-absorbing steering wheels, and integrated headrests.

Seatbelt laws and their evolution

Throughout the late 1960s and early 1970s, several other states followed the National Traffic and Motor Vehicle Safety Act’s precedents and made seatbelt usage mandatory. Then, the advent of seatbelt awareness programs and campaigns led to an unprecedented increase in usage.

In the next three decades, the primary legislation became a state issue, and the law expanded its boundaries accordingly. States introduced various pieces of legislation on seatbelt use, with the first law being passed in Washington D.C. in 1972. While Mississippi was the last state to enforce the use of seatbelts that occurred over 20 years since the introduction of legislation in 1984.

As the laws continued to be enforced, so did the incorporation of seatbelt laws into larger crash prevention legislation, encouraging all automobile manufacturers to abide by strict and uniform safety standards. In 2007, the Federal Motor Vehicle Safety Standards (FMVSS) was enforced, which led to more control by the National Highway Traffic Safety Administration (NHTSA) over the laws and policies that promote car safety.

The long-term benefits of seatbelt laws

Seatbelt laws have offered several long-term benefits, including the prevention of millions of injuries and the saving of numerous lives globally. It has been identified that wearing a seatbelt has a 50 to 60 percent chance of survival, and in focused accidents such as roll-overs, seatbelts have a chance of as much as 89 percent of survival.

Enforcing seatbelt laws is necessary to mitigate and reduce the possibility of car fatalities and accidents and is now a widely accepted and recognized safety measure. It has helped to reduce accident severity and improved post-accident scenarios.


The introduction of seatbelt laws over the last 70 years has been a necessary pursuit of lawmakers worldwide. The benefits are undoubtedly vast and numerous, and the laws have come to stay due to their effectiveness in reducing the possibility of road accidents and fatalities. These laws have served beneficially to all stakeholders and helped promote a culture of safety and confidence in the automotive industry.
