The Evolution Of Seat Belt Laws: A Safety Revolution

The first seat belt law was passed in the US on January 1, 1968, requiring all vehicles (except buses) to be fitted with seat belts in all designated seating positions. However, the use of seat belts remained voluntary until New York became the first state to mandate their use on December 1, 1984. This marked a significant shift in public policy and public perception towards seat belts, which had previously been met with resistance and controversy.

The first seat belt law

This law was the culmination of a long history of seat belt development and advocacy. The first iteration of the seat belt was created by Sir George Cayley, an English engineer who wanted a device to keep him from falling out of his glider in the 19th century. On February 10, 1885, New York City resident Edward J. Claghorn was awarded the first US patent for a vehicular seat belt. However, it wasn't until the 1950s that seat belts started to become standard in cars. In 1959, Nils Bohlin, an engineer at Volvo, created the familiar three-point seat belt. Volvo gave the invention to its rivals for free, to encourage other manufacturers to install seat belts in their cars.

Despite the growing popularity of seat belts, it was still met with resistance from some quarters. In 1961, Wisconsin became the first state to require seat belts to be installed in the front seats of all new cars, but there was no rule that passengers had to wear them. It wasn't until 1984 that New York became the first state to require the use of seat belts, with a $50 fine for non-compliance. This marked a turning point in the adoption of seat belt laws across the country, with 29 states adopting mandatory seat belt laws between 1984 and 1987.

State-by-state laws

In the United States, seat belt legislation varies from state to state. The state of Wisconsin was the first to introduce legislation requiring seat belts to be fitted to the front outboard seat positions of cars, in 1961. Seat belts have been mandatory equipment in all vehicles in the US since 1968. However, the use of seat belts was voluntary until New York became the first state to require vehicle occupants to wear them in 1984.

In some states, such as New Hampshire, Michigan, Arkansas, and Missouri, seat belts in the rear seats are not mandatory for people over the age of 16. New Hampshire is the only state with no law requiring adults to wear seat belts in a vehicle.

The enforcement of seat belt laws also differs between states. In states with primary enforcement, a police officer can pull a driver over for a seat belt violation alone. In states with secondary enforcement, a police officer can only enforce the seat belt law if the driver has been pulled over for another violation. As of 2007, 25 states and the District of Columbia had primary seat belt laws, 24 had secondary seat belt laws, and New Hampshire had no laws.

Seat belt usage rates also vary between states. In 2021, seat belt usage was highest in the western United States, with 94.5% of drivers using their seat belts. The lowest percentage of seat belt usage was found in the midwestern United States, with 88.5% of drivers buckling up.

Public health initiatives

Public education campaigns were critical in raising awareness about the importance of seat belt use. The National Ad Council ran a decades-long campaign, "Buckle Up," which contributed to increasing seat belt use. Law enforcement also played a role by reporting seat belt use alongside car crash fatalities and including photographs of beltless car crash victims in local news broadcasts. Celebrities also participated in public service announcements, encouraging people to wear seat belts.

In addition to public education, the enactment of laws was a crucial factor. The first federal law mandating the installation of seat belts in all new cars was introduced in 1968. However, it was left to individual states to decide whether to require drivers and passengers to wear them. Over time, more states passed legislation requiring the use of seat belts, with New York becoming the first state to do so in 1984. The enforcement of these laws was an important factor in increasing seat belt usage.

Technological improvements also played a part in the adoption of seat belts. In 1959, Nils Bohlin, an engineer at Volvo, invented the three-point seat belt, which provided better restraint for both the upper and lower body compared to the previous two-point lap belts. Volvo gave this invention away for free to encourage other manufacturers to install seat belts in their vehicles, demonstrating their commitment to safety.

The combination of public health initiatives, including education and legislation, along with technological advancements, helped transform seat belt usage into the standard practice it is today, saving thousands of lives each year.

The three-point seat belt

Volvo patented the design but allowed other manufacturers to use it for free, in the interest of safety. The company also spent years promoting the safety benefits of the three-point seat belt, presenting data and studies that showed that the new design reduced injuries and deaths in car crashes. By the time of Bohlin's death in 2002, Volvo estimated that the three-point seat belt had saved more than one million lives in the four decades since its introduction.

In 1968, a federal law was passed in the US requiring all new cars to be equipped with both lap and shoulder belts in the front seat, although this law did not specify the need for any particular design. It wasn't until the 1980s that mandatory seat belt laws began to be introduced in the US, with New York becoming the first state to require vehicle occupants to wear seat belts in 1984.

The first federal law mandating seat belts

The law was modified over time to require three-point seat belts in outboard seating positions and then in all seating positions. However, seat belt use was voluntary until New York became the first state to mandate their use on December 1, 1984.

The 1968 federal law was the culmination of an "uphill battle" to get life-saving seat belts adopted by the public, which included laws, education, and technological improvements. Despite the well-known safety benefits of seat belts, they were not always widely accepted or used. In the late 1970s and early 1980s, seatbelt use was only between 11% and 14%.

The history of seat belts can be traced back to the mid-1800s when Sir George Cayley, a wealthy landowner in Yorkshire, England, invented the first seat belt for his glider. The first US patent for a vehicular seat belt was granted to New York City resident Edward J. Claghorn in 1885. However, it wasn't until the 1950s and 1960s that seat belts started to become more common in automobiles.

In 1959, Swedish engineer Nils Bohlin invented the three-point seat belt, which is now standard in most vehicles. Volvo gave away the design for free to encourage other manufacturers to adopt it, prioritising safety over profit.
