Deer-vehicle crashes are one of the most common wildlife-related road hazards in the United States, occurring millions of times each year and causing significant property damage, injuries, and fatalities.
Unlike most crash types that concentrate in high-traffic urban corridors, deer crash risk is highest on rural roads in specific regions and follows a consistent seasonal pattern tied to deer behavior. Knowing where and when risk peaks gives drivers in affected areas a practical edge.
The National Picture
The State Farm insurance company, which processes more deer collision claims than any other US insurer, publishes an annual deer collision report that tracks state-by-state claim rates. Their data consistently shows that a handful of states account for the majority of deer-vehicle crashes, and that the risk in those states is dramatically higher than national averages.
Pennsylvania leads national rankings in the total number of deer-vehicle crashes most years, reflecting the state’s large whitetail deer population, extensive rural roads, and high traffic volumes through deer habitat. West Virginia, Michigan, Montana, and Iowa consistently appear near the top of the per-driver collision probability rankings. In West Virginia, the probability of any individual driver striking a deer in a given year has been estimated at roughly one in 37, the highest in the country in most reporting periods.
States with large forested areas, significant agricultural land adjacent to roads, and active deer hunting seasons typically show the highest collision rates. States in the Southeast and the Mountain West show lower rates, though none are entirely free of deer crash risk.
When Risk Peaks: The Fall Rut
The timing of deer-vehicle collisions is predictable and tied to white-tailed deer behavior. Two distinct windows produce the highest crash volumes nationally:
October and November are by far the highest-risk months. This period corresponds to the white-tailed deer rut, when bucks are moving extensively across landscapes in search of does, crossing roads at any hour of the day or night. Bucks during the rut are focused on breeding behavior and less attentive to traffic than at other times of the year. Crash rates during peak rut weeks can be two to three times higher than monthly averages.
May and June produce a secondary peak as does move fawns away from birthing areas and yearling deer disperse from their mothers. This increase is smaller than the fall peak but still elevated compared with midwinter or midsummer.
Time of Day and Road Type
Deer crashes follow a dawn and dusk pattern that aligns with deer feeding activity. The windows from 5 AM to 8 AM and from 5 PM to 8 PM produce the highest crash rates by time of day, with the evening window being most dangerous because it overlaps with commuter traffic and declining natural light.
Rural two-lane roads with adjacent woodlands or agricultural fields generate the highest crash rates per mile. However, deer can appear on any road type, including suburban arterials and interstate highways where road corridors pass through forested areas. Underpasses and wildlife crossings in some states have been shown to reduce crossing crashes meaningfully.
States With Highest Deer Collision Risk
Based on consistent data across multiple recent reporting periods from State Farm and the Insurance Institute for Highway Safety:
- Highest risk tier: Pennsylvania, West Virginia, Michigan, Iowa, Montana
- High risk: Minnesota, Wisconsin, South Dakota, North Dakota, Nebraska
- Elevated risk: Missouri, Maryland, Virginia, Ohio, Illinois
- Lower risk: Southern and Southwest states; Pacific Coast states with less whitetail habitat
Risk within states also varies significantly by county and road corridor. Statewide rates mask local hotspots that may be several times higher than the state average.

What to Do If You Hit a Deer
Move your vehicle to the shoulder if safe, turn on hazard lights, and call 911 to report the crash and the deer’s location, as an injured deer on or near the road creates an ongoing hazard. Do not approach an injured deer, as a panicked animal can cause additional injury.
Photograph the damage to your vehicle and the crash location. Contact your insurance company: deer strikes are typically covered under comprehensive coverage rather than collision, and most policies do not charge a deductible for comprehensive deer claims, though this varies by policy.
FAQ: Deer-Vehicle Collisions
What should I do if a deer runs in front of me at highway speed?
Brake firmly and hold your lane when possible. Swerving to avoid a deer often results in more serious crashes than hitting the deer directly, as swerving can send a vehicle off the road or into oncoming traffic.
Which states see the most deer crashes overall?
Pennsylvania, Michigan, and West Virginia consistently rank highest in total crashes. On a per-driver basis, West Virginia, Montana, and South Dakota top the risk rankings.
Are deer more active at certain times of year?
Yes. October and November, during the rut, produce the highest crash rates. A secondary peak occurs in May and June when fawns are dispersed.
Does insurance cover a deer strike?
In most cases, yes, under comprehensive coverage. Comprehensive coverage typically covers animal strikes without the same deductible implications as collision coverage. Verify your policy terms before filing.
Can I legally take a deer that I hit with my vehicle?
Laws vary significantly by state. Many states allow drivers to claim a deer they hit but require reporting to wildlife authorities first. Check your state’s Department of Natural Resources rules.
Are deer crossing signs placed where crashes actually happen?
In most jurisdictions, deer crossing signs are placed based on actual crash history data or known migration corridors rather than randomly. Slowing down in areas marked with these signs is a practical precaution.
Stay Informed With Local Accident Reports
Deer-vehicle collisions are just one of many road hazards drivers face, and risk can shift from year to year as deer populations, road construction, and traffic patterns change.
