Motorcycle Accident Injury Statistics

Motorcyclist fatalities rose 7.5% from 2019 to 2020, yet helmet research consistently points the other way, with helmets reducing head injury by 69% and death by 42% while keeping helmeted riders at lower odds of traumatic brain injury. Follow the sharp contrasts behind that gap, from 60% of hospitalized riders facing severe AIS injuries to the economic toll of $12.3 billion in annual motorcycle crash costs and how factors like no helmet use and speed help explain who gets hurt most.

Motorcyclist fatalities rose 7.5% from 2019 to 2020, even as evidence keeps pointing to what could prevent the worst outcomes. Across studies and registries, helmet use stands out, with large reductions in head injury and death risks alongside higher head injury rates among unhelmeted riders, while crash severity stays strikingly high for hospitalized riders. We’ll also connect the medical and economic burden, including billions in annual costs and the heavy role of traumatic brain injury, right next to the behavioral and road factor patterns that show up again and again in real crash data.
