Seat Belt Law

Citizens Count Editor

When it comes to seat belt legislation, New Hampshire stands alone as the only state in the US where adults are not required to buckle up.

New Hampshire does require that drivers or passengers under the age of 18 wear seat belts. Additional rules apply to the use of car seats for children who are under the age of seven or are 57” or less in height.

History of seat belt law in NH

Most recently, a bill to institute a seat belt law in New Hampshire was tabled in 2018. 

Before that, the last serious attempt to institute a seat belt law in New Hampshire took place in 2009, when the House passed HB 383, sponsored by Rep. Sally Kelly. It was defeated in the Senate by a 16-8 vote.

  • That bill called for a primary safety belt enforcement law, which would have required law enforcement to stop any adult seen driving without a safety belt.
  • The proposed fines were $50 for a first offense and $100 for second or subsequent offenses.
  • The bill would have applied to all vehicles except large school buses, cars manufactured before 1968 and vehicles that make frequent stops for business purposes.

Seat belt usage in NH

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 seat belt use statistics bear this observation out. An average of 73% of NH motorists buckle up, as opposed to the US average of 87%.

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 traffic fatality rate has been declining overall, from 138 fatalities in 2008 to 115 in 2015. At 5.0 per 100,000,  that fatality rate is now lower than the U.S. average of 9.4 per 100,000. 

Public opinion on seat belt laws

Those wondering why New Hampshire remains the only state without a mandatory seat belt law need look no further than public opinion. A Citizen Voices discussion of the issue found that 88% of respondents opposed legislating seat belt usage, arguing that buckling up should remain a personal choice, not a government requirement.

Federal laws

The federal government strongly encourages states to pass primary or secondary seat belt laws, citing statistics that show higher rates of fatalities among non-restrained drivers.

Past federal efforts to encourage the passage of seat belt legislation include offering substantial grants to states that enacted such laws, or strengthened existing ones. The seat belt legislation proposed in New Hampshire in 2009 would have qualified the state for such funds.

Other states

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

  • A primary law means that law enforcement can stop motorists solely for not wearing a seat belt.
  • Secondary 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. 
  • The CDC states that primary seat belt laws result in a 9% higher rate of seat belt usage than secondary laws.


"For" Position

By Citizens Count Editor

NH should pass a mandatory seat belt law.

  • Though only 27% of NH motorists do not wear seat belts, 62% 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%.
  • In 2008, the National Highway and Traffic Safety Administration estimated that enacting a primary seat belt law in NH 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.

"Against" Position

By Citizens Count Editor

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.

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:

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.
