Seat Belt Laws: Private Property Exempt?

Seat belt laws are a contentious issue in the United States, with some people arguing that they infringe on personal freedom and constitutional rights. However, the laws have been shown to increase seat belt use and reduce crash-related injuries and deaths. While most seat belt laws are left to individual state legislation, the effectiveness of these laws in improving road safety has been demonstrated. For example, primary enforcement seat belt laws, which allow law enforcement officers to stop vehicles solely for seat belt violations, have been shown to be more effective than secondary enforcement laws, which require another reason for the traffic stop. The debate around seat belt laws centres on the balance between public safety and individual liberty, and it remains a divisive issue in the United States.

Seat belt laws in the US are mostly left to state law

Seat belt laws in the United States vary across different states and territories. While the federal government has enacted laws regarding the installation of seat belts in vehicles, the enforcement of seat belt use is largely left to individual state laws.

The first seat belt law at a federal level was Title 49 of the United States Code, Chapter 301, Motor Safety Standard, which came into effect on January 1, 1968. This law mandated that all vehicles (excluding buses) be fitted with seat belts in all designated seating positions. This law has since been amended to require three-point seat belts in all outboard and then all 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.

Currently, each state has its own primary or secondary enforcement laws regarding seat belt use. Primary enforcement laws allow law enforcement officers to stop and ticket a driver or passenger for not wearing a seat belt, without the need for any other traffic offense to have taken place. On the other hand, secondary enforcement laws require that another citable traffic violation, such as speeding or running a stop sign, be committed for a driver or passenger to be cited for not wearing a seat belt. As of 2013, 17 states and the District of Columbia had primary enforcement laws covering all seating positions, while 16 states had similar laws covering only the front seats.

The specific laws and their enforcement vary greatly from state to state, and even within states, depending on the age of the rider and the seat they are occupying. For example, while the recommended age for a child to sit in the front passenger seat is 13 across the US, the laws regarding children in cars often do not apply to those under a certain age. Additionally, in some states, such as Colorado, children not being properly restrained is considered a primary offense and carries a larger fine.

In addition to state laws, some private property owners can choose to enforce seat belt laws on their premises. For example, gated communities, malls, and other entities may request that their local government include their private property under the jurisdiction of the state's vehicle code, which would then require the display of appropriate signage.

Primary enforcement laws allow police to stop a driver solely for not wearing a seat belt

In the United States, primary enforcement laws allow police officers to stop and ticket a driver if they observe a violation, such as not wearing a seat belt. This means that a police officer can pull over a driver solely for not wearing a seat belt and issue a citation. As of 2017, thirty-four states, the District of Columbia, American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands have primary enforcement laws for front seats.

Primary enforcement laws are more effective at encouraging people to wear seat belts. In 2006, the frequency of never using a seat belt was twice as high in states with secondary enforcement compared to those with primary enforcement laws. States that switched from secondary to primary enforcement laws between 1993 and 2000 saw a 14-percentage-point increase in observed seat belt use. Research has also shown that primary seat belt laws are more effective at reducing crash deaths than secondary laws.

However, it is important to note that seat belt laws may not apply on private property. For example, in California, the Vehicle Code only mentions the use of seat belts on "highways," which includes streets. This means that on private property, such as parking lots, the seat belt law may not be enforceable unless measures have been taken to include private property under the Vehicle Code's domain.

While primary enforcement laws give police officers the authority to stop a driver solely for not wearing a seat belt, it is worth noting that seat belt use laws often do not apply to children. Separate child restraint laws are in place to address this. Additionally, the recommended age for a child to sit in the front passenger seat is 13 years old.

Secondary enforcement laws require police to have another reason to stop a driver before citing them for not wearing a seat belt

In the United States, seat belt laws are divided into two categories: primary and secondary enforcement laws. While primary enforcement laws allow police officers to stop and ticket a driver for not wearing a seat belt, secondary enforcement laws require officers to have another reason to stop a driver before citing them for a seat belt violation.

In states with secondary enforcement laws, not adhering to the state's seat belt laws is not a sufficient reason for a police officer to pull over a driver. However, if a driver is stopped for another primary violation, such as speeding or running a stop sign, they can be cited for not wearing a seat belt in addition to the primary violation.

As of 2017, 15 out of 50 states consider the non-use of seat belts as a secondary offense. This means that a police officer cannot solely stop and ticket a driver for not wearing a seat belt unless another violation has been committed. For example, if a driver is pulled over for speeding (a primary violation), they can be charged for both speeding and not wearing a seat belt.

It is important to note that seat belt laws in the United States are largely determined by state law. While most states have back-seat seat belt laws, there are a few states without such laws. Additionally, rules for minors or young children may differ from those for adults, with more stringent requirements for younger passengers in some states.

California Vehicle Code says people need to be buckled up if on a highway

In California, most seat belt laws are left to state law. The California Vehicle Code (CVC) states that people need to be buckled up if they are on a "highway". The CVC defines a highway as a "road that has been designated for the exclusive use of public transit buses". This includes streets as well.

However, it's important to note that the CVC does not apply to private property. The law on private property is different, and in general, few driving laws are in effect, including the seat belt law. Unless measures have been taken to bring private property under the CVC's domain, most driving laws do not apply. Gated communities, malls, and other entities can request that their private property be covered by the CVC, and in these cases, signs will be posted to indicate that the Vehicle Code is enforced.

California was the first state to change non-use of seat belts from a secondary to a primary offense in 1993. This means that a police officer can stop and ticket a driver solely for not wearing a seat belt, without the need for another primary violation such as speeding.

Seat belt laws are effective in reducing car crash deaths

Seat belt laws are highly effective in reducing car crash deaths. In 2017, seat belts saved an estimated 14,955 lives in the US alone. From 1975 to 2017, seat belts are estimated to have saved 374,276 lives. While more recent estimates are not available, seat belt usage has increased since 2017, with a usage rate of 91.6% in 2022. This suggests that seat belts are likely saving even more lives today than they were in 2017.

The effectiveness of seat belts in reducing car crash deaths is further supported by a study conducted in Nigeria, which found that the mortality rate for patients who did not use seat belts was 79%, compared to 21.1% for those who did. Additionally, the study found that patients who did not wear seat belts were eight times more likely to die in a crash.

The benefits of seat belts are also evident when examining the risks associated with not wearing them. The National Highway Traffic Safety Administration (NHTSA) estimates that not wearing a seat belt increases the risk of front-seat passenger car occupant deaths by 45% and moderate to critical injuries by 50%. Similarly, not wearing a seat belt in a light truck increases the risk of fatal injury by 60% and moderate to critical injury by 65%.

Furthermore, seat belt laws implemented through primary enforcement, which allows law enforcement officers to stop and ticket drivers solely for seat belt violations, are more effective in increasing wearing rates than secondary enforcement laws, which require an additional violation such as speeding.

While seat belt laws may vary depending on the state and whether they fall under primary or secondary enforcement, the evidence is clear that seat belt laws are effective in reducing car crash deaths. By increasing seat belt usage, these laws play a crucial role in enhancing road safety and saving lives.
