Risk Factors
Speeding in Motorcyclist Fatalities by age group
(2021-2025* Average for the State of Florida)
Speeding-related motorcyclist fatalities are most common among younger riders. The highest proportion is observed among riders ages 21–29, followed closely by riders under 21. After age 30, the proportion generally declines with each successive age group, with no speeding-related fatalities observed among riders ages 70–79 or 80 and over in the current dataset.
Helmet Usage in Motorcyclist Fatalities by age group
(2021-2025* Average for the State of Florida)
Helmet usage among fatally injured motorcyclists is highest among younger riders. Helmet use generally declines through the middle-age groups before increasing again among riders ages 70–79 and 80 and over. This pattern suggests helmet use varies by age and does not follow a strictly decreasing trend across all age groups.
Unendorsed Motorcyclist Fatalities by age group
(2021-2025* Average for the State of Florida)
Younger riders are more likely to be unendorsed in fatal motorcycle crashes. The highest proportion of unendorsed riders is found in the 21–29 age group, with similar percentages among riders ages 30–49. The proportion steadily decreases among older age groups and reaches zero for riders 80 and over in the current dataset.
Impairment in Motorcyclist Fatalities BY age group
(2021-2025* Average for the State of Florida)
Impairment-related motorcyclist fatalities are most prevalent among middle-aged riders. The proportion increases from the youngest age groups and peaks among riders ages 40–49, before gradually declining in the older age groups. This pattern indicates that impairment is a more significant contributing factor among middle-aged riders than among the youngest or oldest riders.
motorcyclist fatality percentage by impairment type
(For the State of Florida)
Alcohol and drug impairment continue to contribute to motorcycle fatalities across the state. Among the three impairment categories, Alcohol Only accounts for the largest share in each year of the current dataset, while Alcohol and Drugs consistently represents the smallest share. All three impairment categories show a gradual decline from 2021 through 2025, indicating a downward trend in the proportion of impairment-related motorcycle fatalities during this period.
In 2025, Alcohol Only remained the most common impairment category, followed by Drugs Only and Alcohol and Drugs. Although the proportions have declined over the five-year period, alcohol- and drug-related impairment continue to be contributing factors in fatal motorcycle crashes.
According to the National Highway Traffic Safety Administration (NHTSA), alcohol can negatively affect many of the skills necessary to safely operate a motorcycle:
- A BAC as low as 0.02% can impair visual function, judgment, and the ability to perform multiple tasks while riding.
- Higher BAC levels can significantly reduce concentration, reaction time, coordination, and vehicle control, increasing the risk of a fatal crash.
- Impairment continues to be a significant contributing factor in fatal motorcycle crashes, despite the decline in alcohol- and drug-related motorcycle fatalities in recent years.
