Step 1 : Introduction to the question "What is the only U.S. state without a mandatory seat belt law for adults?"
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. According to the National Highway Transportation and Safety Administration, 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%. New Hampshire does require that drivers or passengers under the age of 18 wear seat belts.
