Only a few states have exceptions or partial exemptions for helmet use. Here are some examples:
New Hampshire: New Hampshire is the only state in the U.S. that does not have a mandatory helmet law for riders aged 18 and older. However, riders who choose not to wear a helmet must carry a minimum amount of medical insurance coverage.
Iowa: In Iowa, motorcycle riders who are 18 years or older are not required to wear a helmet if they have held a motorcycle license for at least one year.
Illinois: Illinois does not have a universal helmet law. However, riders under the age of 18 must wear helmets, and riders aged 18 and older must wear helmets if they have less than $20,000 in medical insurance coverage.
The reasons for the differences in helmet laws across states can vary. Some factors that may influence these variations include:
Individual Freedom and Personal Choice: States with less stringent helmet laws or exemptions may prioritize individual freedom and allow riders to make their own choices regarding helmet use.
Public Safety Concerns: States with mandatory helmet laws often prioritize public safety and aim to reduce the severity of injuries and fatalities in motorcycle accidents. These states believe that helmet use can significantly decrease the risk of head injuries.
Political and Cultural Factors: Helmet laws can be influenced by political and cultural factors. Different states may have varying attitudes and perspectives on personal freedom, government intervention, and public safety.
It's important to note that laws can change over time, and it's always advisable to consult the most up-to-date information on helmet laws in specific states before riding a motorcycle without a helmet.
