The National Highway Traffic Safety Administration (NHTSA) estimates that, since 2002, more than 25,000 lives have been saved by wearing motorcycle helmets. This includes 1,872 lives saved in 2017. If all motorcyclists had worn helmets, an additional 802 lives could have been saved in 2017. Motorcycle helmets are estimated to be 37% effective in preventing fatal injuries to motorcycle operators and 41% effective for motorcycle passengers.
According to the National Occupant Protection Use Survey (NOPUS), use of Department of Transportation (DOT)-compliant helmets by all motorcyclists (riders and passengers) was 65.2% in 2017. Helmet use has increased by 13% since 2002, from 57.7%.
- Data Table
Observed use of DOT-compliant helmets in states with universal helmet laws was significantly higher than in states with weak or no helmet laws (87.0% compared to 43.7%). Use of non-compliant helmets is also greater in states with universal helmet laws, at 9.9% versus 4.3%.
