Seat Belt Law

Citizens Count Editor

If you are 18 or older, you don’t have to wear a seatbelt in New Hampshire. New Hampshire is the only state in the U.S. where adults are not required to buckle up. 

NH child seat laws 

New Hampshire has a seatbelt law requiring those under 18 to wear a safety belt when driving or riding in a car. It also mandates that passengers under age seven must be fastened by a child restraint system—such as a booster seat—with specific rules spelled out by the federal government. The provision doesn’t apply if the child is 57 inches tall or taller.  

Nseat belt statistics 

According to the National Highway Transportation and Safety Administration (NHTSA), states with stronger seat belt laws generally have higher rates of usage than those with weaker or no laws. New Hampshire’s adult seat belt usage was actually the lowest in the U.S. in 2018, averaging 76.4%. The national average was 89.6%. 

Additional New Hampshire  seat belt use facts: 

  • Female drivers are 10% more likely to wear seat belts than male drivers.   

  • Pickup drivers are 20% less likely to wear a seat belt than SUV or van drivers. 

Even in the absence of a seat belt law, New Hampshire's roads are among the safest in the country.  

Federal laws 

The federal government strongly encourages states to pass primary or secondary seat belt laws but does not require it, citing statistics that show higher rates of fatalities among non-restrained drivers 

Seat belt laws in other states 

The other 49 states either have primary or secondary seat belt laws. 

  • A primary seat belt law means that law enforcement can stop motorists solely for not wearing a seat belt. 

  • Secondary seat belt laws mean that drivers can only be ticketed for neglecting to use a seat belt after they have been stopped for another offense, such as a speeding violation.

NH should pass a mandatory seat belt law.

  • Though only 23.6% of NH motorists do not wear seat belts, 70% of NH traffic fatalities  were unrestrained drivers or passengers. 

  • Seat belt use by drivers or front seat passengers in cars has been said to reduce the risk of death by 45% and of serious injury by 50%. 

  • Seat belt use has an even greater impact in light trucks and SUVs, decreasing the risk of injury  by 65%. 

  • A study by the  National Highway and Traffic Safety Administration estimated  that enacting a primary seat belt law in New Hampshire would result in $7.9 million in savings to state government, federal government and insurance companies, primarily in reduced medical expenses. 

  • Research shows  that traffic fatality rates decline in states that enact seat belt laws: an average of 21% in states with primary laws and 7% in states with secondary laws.

NH should not pass a mandatory seat belt law.

  • It is not the government’s job to legislate common sense. The choice to wear a seat belt should remain up to the individual. 

  • Primary seat belt laws give law enforcement an excuse to stop motorists even if no other infraction has been committed, which could increase minority profiling. 

  • Education, not a law, is the best way to increase seat belt usage. A law alone will not change the minds of those who do not currently buckle up. 

  • Seat belt laws distract law enforcement from focusing their attention on more serious offenses, such as speeding or distracted driving.

We have a law banning cell phones and there is zero effort even trying to enforce that.
Cell-phone use while driving results in distracted drivers injuring and killing many many other people.

Wearing a seat belt is my choice for my safety. It is irrelevant to the safety of others.


Growing up on military bases, it was ingrained into my head that any time I got into a moving vehicle I must immediately buckle up. Why someone wouldn't automatically use this safety feature to prevent becoming a human projectile and receiving serious injuries and possibly death is unfathomable to me. I'm surprised that NH is the only state that doesn't require drivers and passengers over 18 to wear a seat belt. It's interesting to also read that in a survey conducted, a whopping 88% were opposed to adults being required to wear seat belts. It just seems like common sense to buckle up. Here are the surprising results of that survey:
