The research found that drivers aged 85 and older experienced 14.47 traffic fatalities per 100K licensed drivers in 2024, compared with 7.71 among motorists aged 65 to 74.
That difference represents an 88% higher fatality rate for the oldest driving population.
The disparity comes as the United States experiences continued growth in its senior driving population.
Between 2020 and 2024, the number of licensed motorists aged 65 and older increased by 14.1%, reaching 54.39 million. During the same period, senior driver deaths rose 15.9%, from 4,241 to 4,917.
Although the figures reveal a growing traffic safety challenge, the study also highlights an important distinction: higher fatality rates among older adults do not necessarily indicate that they cause more crashes.
Instead, the findings suggest that physical vulnerability, intersection design, traffic conditions and vehicle safety features may play important roles in determining crash outcomes.
Fatality Rates Increase Considerably After Age 75
Senior drivers are frequently grouped into one broad demographic category, but fatality statistics reveal substantial differences between those in their late 60s and drivers over 85.
In 2024, motorists aged 65 to 74 accounted for 2,508 traffic fatalities.
Drivers aged 85 and older accounted for 663 deaths.
Although the younger group recorded nearly four times as many fatalities, it also represented a much larger proportion of licensed senior motorists.
Approximately 32.54 million Americans aged 65 to 74 held driver’s licenses in 2024, compared with 4.58 million drivers aged 85 and older.
When fatality totals were adjusted to account for these differences, the oldest motorists experienced substantially higher death rates.
Senior Driver Fatality Rates by Age Group, 2024
| Age Group | Fatalities per 100K Licensed Drivers | Difference From Ages 65–74 |
|---|---|---|
| Ages 65–74 | 7.71 | Baseline |
| Ages 75–84 | 10.11 | +31.1% |
| Ages 85+ | 14.47 | +87.7% |
The fatality rate increased by approximately 31% between the youngest and middle senior age groups.
It then increased another 43% among drivers aged 85 and older.
The findings show that the risk of a fatal outcome rises substantially within the senior driving population itself.
However, differences in fatality rates should not automatically be interpreted as differences in driving ability.
Older motorists may face more severe consequences when involved in crashes because of physical changes associated with aging.
Research from the Insurance Institute for Highway Safety indicates that susceptibility to injury and complications following a collision contributes significantly to elevated fatal crash rates among older adults.
The Oldest Drivers Face Higher Fatal Crash Involvement per Mile Traveled
The relationship between aging and crash risk becomes more pronounced when examining driving exposure.
Older adults generally drive fewer miles than younger motorists, meaning annual death totals do not fully capture the risks associated with their time on the road.
Insurance Institute for Highway Safety research measuring fatal crash involvement per 100 million miles traveled found that rates increase substantially among older driver groups.
For drivers aged 70 to 74, the fatal crash involvement rate was 2.1 per 100 million miles traveled.
The rate increased to 5.3 among drivers aged 80 to 84 and reached 7.9 among those aged 85 and older.
Fatal Crash Involvement by Age and Distance Traveled
| Driver Age | Fatal Crash Involvements per 100 Million Miles |
|---|---|
| Ages 65–69 | 1.6 |
| Ages 70–74 | 2.1 |
| Ages 75–79 | 2.8 |
| Ages 80–84 | 5.3 |
| Ages 85+ | 7.9 |
Source: IIHS analysis of 2022 driving exposure and fatal crash involvement.
Drivers aged 85 and older recorded a fatal crash involvement rate approximately 3.8 times that of motorists aged 70 to 74.
The comparison provides a clearer picture of how frequently fatal crashes occur relative to the distance driven.
It also illustrates why the oldest motorists require particular consideration when designing roadway safety strategies.
However, involvement in a fatal collision does not necessarily indicate responsibility for causing it.
The data identifies an elevated rate of involvement in crashes resulting in death, which can reflect multiple factors, including increased physical vulnerability.
Intersections Present a Particular Challenge for Older Motorists
One of the most important differences between older and younger drivers involves collisions at intersections.
According to the Insurance Institute for Highway Safety, multiple-vehicle intersection crashes represented 43% of fatal crash involvements among passenger vehicle drivers aged 80 and older in 2024.
Among drivers aged 20 to 64, the corresponding figure was approximately 24%.
For drivers aged 85 and older specifically, multiple-vehicle intersection crashes accounted for 46% of their fatal crash involvements.
This concentration suggests that complex traffic environments deserve particular attention when evaluating senior driver safety.
Intersections often require motorists to evaluate several competing hazards simultaneously, including approaching vehicles, turning traffic, pedestrians and traffic signals.
For drivers experiencing reduced vision, slower reaction times or other functional limitations, complicated roadway environments may present additional challenges.
The findings support examining intersection safety improvements that could reduce the consequences of driver error.
Potential interventions include:
- More visible traffic signals and pavement markings.
- Dedicated left-turn lanes and protected turning phases.
- Improved lighting at intersections and pedestrian crossings.
- Clearer signage that provides additional time for decision-making.
- Roadway configurations that reduce vehicle speeds and simplify traffic movements.
- Intersection redesigns that reduce opportunities for severe angle collisions.
These approaches would not exclusively benefit older drivers.
Reducing intersection complexity and improving visibility could also improve safety for pedestrians, cyclists and motorists across all age groups.
Distraction Statistics Challenge Common Assumptions About Senior Drivers
Although distracted driving remains a significant national traffic safety concern, the available federal data does not establish that the oldest motorists are uniquely susceptible to distraction.
The CR Legal analysis found that distraction was recorded in approximately 5% of driver fatalities across each of the three senior age groups examined.
Those groups included drivers aged 65 to 74, 75 to 84 and 85 and older.
The similarity across age groups challenges the assumption that advancing age necessarily corresponds with higher recorded distraction levels.
National Highway Traffic Safety Administration data also identified several specific distraction factors among older drivers involved in fatal crashes.
Recorded Distraction Factors Involving Older Drivers
| Distraction Factor | Recorded Cases |
|---|---|
| Mobile Phone Use | 29 |
| Person or Object Outside the Vehicle | 29 |
| Vehicle-Integrated Controls | 14 |
| Another Vehicle Occupant | 10 |
Figures represent selected recorded distraction factors among older drivers involved in fatal crashes, not an exhaustive breakdown of all crashes.
Phone-related distraction was also identified separately by age.
Among drivers aged 65 to 74, 20 were recorded as using a mobile phone during a fatal crash.
For drivers aged 75 and older, nine such cases were recorded.
However, NHTSA cautions that distracted driving is likely underreported in crash statistics.
Consequently, the relatively small number of recorded cases should not be interpreted as evidence that distraction is absent from other collisions.
The findings instead suggest that attention should be directed toward documented crash circumstances rather than assumptions based solely on a driver’s age.
Senior Drivers Accounted for More Than 15% of Drivers Involved in Fatal Crashes
The research also examined how frequently older motorists were represented among drivers involved in fatal crashes nationwide.
In 2024, 8,484 drivers aged 65 and older were involved in crashes resulting in at least one death.
That represented 15.3% of the 55,620 drivers involved in fatal crashes across the United States.
However, the proportion varied considerably by state.
States With Notable Senior Driver Shares of Fatal Crash Involvement
| State or Jurisdiction | Share of Drivers in Fatal Crashes Aged 65+ |
|---|---|
| North Dakota | 23.8% |
| South Dakota | 22.9% |
| Nebraska | 22.0% |
| Massachusetts | 20.1% |
| United States | 15.3% |
| Delaware | 10.8% |
| Vermont | 10.6% |
| Washington, D.C. | 8.2% |
North Dakota recorded the highest proportion, with nearly one in four drivers involved in fatal crashes aged 65 or older.
South Dakota and Nebraska also exceeded the national average substantially.
Massachusetts provides an important contrast between crash involvement and driver fatalities.
Although older motorists represented 20.1% of drivers involved in fatal crashes in Massachusetts, the state’s senior driver fatality rate was only 4.94 deaths per 100K licensed older drivers.
That was considerably below the national fatality rate of 9.04.
The difference illustrates why crash involvement and fatality risk must be examined separately.
A state can have a relatively large share of older drivers involved in fatal collisions without recording a correspondingly high rate of senior driver deaths.
Geographic Differences Show That Age Alone Cannot Explain Fatality Rates
The study also identified significant differences between states when senior fatalities were adjusted for their licensed older driving populations.
Mississippi recorded the nation’s highest senior driver fatality rate in 2024, at 20.39 deaths per 100K licensed senior motorists.
South Dakota followed with 18.98.
Meanwhile, Rhode Island recorded the lowest rate at 2.11, followed by Hawaii at 3.28 and Vermont at 4.26.
These differences were substantial.
Mississippi’s senior driver fatality rate was approximately 9.7 times that of Rhode Island.
Florida’s findings were also notable.
Despite having approximately 4.36 million licensed drivers aged 65 and older, Florida recorded a fatality rate of 8.23 per 100K, below the national average.
The state accounted for the second-highest number of senior driver deaths, with 359 fatalities, but ranked only 30th on a population-adjusted basis.
California recorded 272 senior driver fatalities, the third-highest total nationally, yet its fatality rate was only 5.16.
These differences suggest that regional driving environments and patterns of roadway exposure must be considered alongside age.
They also demonstrate why policies targeting older motorists cannot rely exclusively on national fatality averages.
Vehicle Technology Could Help Prevent a Significant Share of Older Driver Deaths
While some roadway safety debates focus on restricting older drivers, existing vehicle safety technology may offer another approach.
Insurance Institute for Highway Safety research suggests that three types of driver assistance systems could be relevant to preventing as many as one-quarter of older driver fatalities.
These technologies include front crash prevention, blind-spot detection and lane-departure warning systems.
Each addresses a different category of driving hazard.
Front crash prevention systems can warn motorists about potential collisions and, in some vehicles, apply the brakes automatically.
Blind-spot detection systems can alert drivers to nearby vehicles that may not be visible through standard mirrors.
Lane-departure warning systems can notify motorists when their vehicles begin moving outside marked travel lanes.
Together, these technologies may reduce certain crashes associated with delayed reactions, visibility limitations or driver error.
Vehicle protection is also important.
Older adults can be more susceptible to serious injuries in collisions, meaning improvements in occupant protection may provide substantial benefits even when crashes cannot be prevented entirely.
Licensing Policies May Need to Focus on Individual Driving Ability
Differences in state licensing policies present another consideration.
Some states require older drivers to renew their licenses more frequently or complete additional vision screenings.
Others have fewer age-specific licensing requirements.
Organizations including the Governors Highway Safety Association have supported approaches that consider individual driving fitness, medical conditions and driving history.
Such approaches can include in-person renewals, referrals for medical evaluations and restrictions tailored to specific driving circumstances.
For example, drivers who experience difficulty navigating nighttime traffic may benefit from individualized assessments or restrictions rather than losing their driving privileges solely because they reach a particular age.
Similarly, improvements in intersection design and vehicle technology may help older motorists maintain mobility while reducing safety risks.
The distinction is particularly important because driving often supports independence, access to healthcare and participation in everyday activities for older adults.
Growing Senior Driver Population Creates New Safety Challenges
The growth of America’s older driving population is expected to keep senior road safety an important consideration for transportation agencies and policymakers.
CR Legal’s research found that annual deaths among licensed senior drivers increased from 4,241 in 2020 to 4,917 in 2024.
However, the study’s age-specific findings show that the oldest motorists face substantially higher fatality rates than younger seniors.
Drivers aged 85 and older experienced an 88% higher fatality rate than those aged 65 to 74, while federal crash records identified elevated fatal crash involvement at intersections among the oldest age groups.
These findings indicate that improving senior driver safety requires more than measuring the number of older adults involved in crashes.
Understanding physical vulnerability, roadway conditions, vehicle technology and individual driving capabilities may provide a more effective foundation for preventing serious injuries and deaths.
As the population of licensed senior motorists continues to expand, the challenge will be improving traffic safety without assuming that chronological age alone determines whether someone can drive safely.
