A motorcyclist's risk of death is twenty-eight times higher per mile traveled than a passenger car occupant's, a sobering statistic that underscores why understanding the data behind motorcycle accidents—from helmet use to demographics and common crash scenarios—is critical for every rider.
Key Takeaways
- In 2022, motorcyclists accounted for 14% of all traffic fatalities in the United States despite comprising only 3% of registered vehicles
- Motorcycle rider deaths reached 5,932 in 2021, marking the highest since 1975 with a rate of 28.04 per 100,000 registered motorcycles
- From 1975 to 2021, motorcycle fatalities increased by 414% while vehicle miles traveled only rose by 1,336%
- In 2021, 89,000 motorcyclists were injured requiring hospital treatment, with 75,000 nonfatal injuries reported to police
- Lower extremity injuries accounted for 30% of all motorcycle crash injuries in a 2019 study of 5,000 cases
- In 2020, motorcyclists suffered 84,000 injuries, a 7% decrease from 2019 due to reduced traffic
- Other vehicle drivers failing to see motorcyclist caused 56% of multi-vehicle crashes in 2020 IIHS study
- Lane splitting by motorcyclists increased crash risk by 1.4 times in California 2019 data
- 42% of motorcycle crashes involved another vehicle violating right-of-way in 2019 NHTSA report
