In 2019, riders represented only a small slice of the vehicle population, but their crashes carried major consequences. This page examines who was involved and what contributed, including helmet use, rider behavior, and roadway factors behind fatal outcomes. You’ll also look at the scale of injuries and economic costs, plus when crashes are most likely to occur across the spring–summer riding season.
Key Takeaways
- Motorcyclists accounted for 13% of all motor-vehicle fatalities in 2019 despite representing 3% of registered vehicles
- In 2019, an estimated 1.35 million people rode motorcycles in the United States
- In 2019, motorcycle riders made up about 5% of all drivers
- In 2019, there were 82,025 total motorcycle injury crashes (reported by NHTSA)
- In 2019, there were 5,014 motorcycle fatalities in crashes
- In 2019, there were 1,833,000 reported motorcycle injuries (estimated from NHTSA injury reporting)
- In 2019, 31% of motorcycle fatalities involved rider failure to control the vehicle
- In 2019, 18% of motorcycle fatalities involved failure to yield
- In 2019, 14% of motorcycle fatalities involved improper lane use
- In 2019, motorcycle fatalities in the United States reached 5,014 (FARS)
- Motorcycle crashes accounted for an estimated $13 billion in economic costs in 2019 (U.S. estimate; NHTSA crash cost analysis)
- In 2019, there were 36,096 traffic fatalities overall in the United States (NHTSA)
- In the United States, 48% of motorcycle crashes occur in the spring-summer riding period (NHTSA seasonal analysis)

Interpretation
Prevention & Mitigation Interpretation
For Motorcycle Prevention and Mitigation, the data show that crashes peak during spring summer with 48% occurring in that period, and that helmet use makes a major difference in outcomes, with helmeted riders about 37% less likely to die and about 67% less likely to suffer head injury.
