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.
Key Takeaways
- Motorcyclist fatalities increased 7.5% from 2019 to 2020
- A 2019 population-based study reported that motorcyclists represented about 3% of licensed drivers but 17% of road traffic deaths (U.S. context)
- A 2017 systematic review found helmet use reduces the risk of death among motorcyclists by about 37%
- A 2018 Cochrane review reported that helmets are associated with reduced risk of head injury and death in motorcycle riders
- Motorcyclists without helmets were about 2.2 times more likely to sustain head injury in a U.S. trauma registry analysis
- A 2020 U.S. study estimated that motorcycle crashes caused $12.3 billion in economic costs annually (medical, work loss, property damage)
- A 2020 estimate attributed $16.7 billion in lifetime medical costs to traumatic brain injuries from motor vehicle crashes involving motorcycles (study-specific scope)
- Motorcycle crash injury severity is disproportionately high: in a 2018 paper, 60% of hospitalized motorcycle crash patients had AIS severity ≥3
- A 2021 study found that head injuries were the most frequent severe injury region in motorcycle crash victims (share reported in paper)
- A 2019 systematic review found that motorcycle riders have a higher risk of injury in crashes than car occupants (relative risk/odds reported)
- A 2022 review reported that traumatic brain injury occurred in about 30–40% of motorcycle crash patients (range depending on included studies)
- In a 2018 U.S. analysis, 36% of motorcycle crashes involved failure to yield the right of way (crash factor distribution reported)
- In a 2014–2018 review, alcohol involvement was present in 25–30% of fatal motorcycle crashes (range reported across studies)
- A 2020 paper reported that speed was a contributing factor in 23% of fatal motorcycle crashes (percentage in study)
- A 2018 randomized or quasi-experimental study reported that anti-lock braking systems (ABS) reduce motorcycle crash injuries (relative reduction reported)
Helmeted riders face far lower head injury and death risk, despite rising motorcycle fatalities and huge crash costs.

Injury Patterns3 stats
01
The WHO estimates that non-fatal injuries are far more common than fatalities, with tens of millions of road traffic injuries requiring medical care each year worldwide.
02
In 2019, the CDC reported that traumatic brain injuries (TBIs) account for a large portion of head injuries from motor vehicle crashes (including motorcycle-related head trauma) in U.S. injury surveillance summaries.
03
The International Transport Forum (ITF) reports that motorcyclists are disproportionately represented in severe road traffic injuries relative to car occupants in many countries (cross-country comparative evidence).
Interpretation
Injury Patterns Interpretation
Under Injury Patterns, motorcycle-related road traffic injuries reflect a consistent trend that non-fatal cases vastly outnumber fatalities worldwide, while in the United States traumatic brain injuries make up a major share of head injuries from motor vehicle crashes and international comparisons show motorcyclists are more likely than car occupants to suffer severe injuries.

Countermeasures2 stats
01
U.S. DOT/NHTSA has a Motor Vehicle Safety Standard for helmets (FMVSS No. 218) defining performance requirements for motorcycle helmets sold in the U.S., constraining helmet design and effectiveness.
02
U.S. NHTSA’s motorcycle rider training guidance emphasizes that training can improve crash avoidance behaviors; the Motorcycle Safety Foundation (MSF) reports that RiderCourse completion can improve certain rider skills measured in training assessments.
Interpretation
Countermeasures Interpretation
Countermeasures are making a clear difference because the U.S. DOT NHTSA helmet standard FMVSS No. 218 tightly governs motorcycle helmet performance, and NHTSA training guidance supported by MSF shows that completing RiderCourse can improve specific rider skills assessed in training.
