Fault in a motorcycle crash shapes more than the police report. In 2021, 62% of fatal motorcycle crashes involving another vehicle were blamed on the automobile driver failing to yield the right of way. The patterns below break down how those fault assignments shift across intersections, lanes, and rider actions.
Key Takeaways
- In 2021, 62% of fatal motorcycle crashes involving another vehicle were attributed to the automobile driver's failure to yield right-of-way
- NHTSA 2021: Alcohol impairment of motorcyclists was present in 30% of fatal crashes
- In 2021 NHTSA data, 42% of single-vehicle motorcycle crashes were due to rider excessive speed
- In 2022 GHSA report, speeding contributed to 33% of all motorcycle fatalities where rider fault was primary
- NHTSA 2020: Failure of other drivers to perceive motorcycles contributed to 56% of multi-vehicle crashes
Motorcycle accidents most often result from rider or other road user faults, shaping how claims are decided.
