Late fall is the most dangerous time of year for collisions with deer and other animals. Days are shorter, commutes happen around dusk, and deer are on the move during mating and hunting season. Insurance data consistently shows claims climbing in October and peaking in November. A collision with a large animal can total a car, and swerving to avoid one can be even more dangerous. Here is what the data says and how to lower your risk.
When and Where the Risk Is Highest
Research from the Highway Loss Data Institute, an affiliate of the Insurance Institute for Highway Safety (IIHS), found that animal-strike insurance claims rise rapidly in October, peak in November and fall off in December and January. In its analysis, November claim frequency was roughly double the typical monthly average, and nearly nine in 10 animal collisions involved the front of the vehicle.
State Farm’s latest data estimates more than 1.6 million animal collision claims in the U.S. between July 2025 and June 2026, putting the average driver’s odds at about 1 in 145. November, October and December are the riskiest months, and deer are by far the most common animal involved. West Virginia has consistently ranked as the state with the highest odds, with states such as Montana, Pennsylvania, Wisconsin and Michigan also near the top.
These crashes can be deadly. IIHS reports that 210 people died in U.S. crashes involving collisions with animals in 2024. In many of those deaths, the collision with the animal itself was the most harmful event, but rollovers and crashes into fixed objects, often after swerving, also played a role.
Habits That Lower Your Risk
- Be most alert from dusk to dawn. Deer are most active in early morning and evening, which overlaps with fall commutes.
- Watch for crossing signs and wooded edges. Deer crossing signs are placed where collisions have occurred. Fields, creeks and tree lines next to the road are common crossing points.
- Use high beams when the road is clear. On dark roads without oncoming traffic, high beams help you see eyeshine sooner.
- Slow down. Lower speed gives you more time to react and reduces impact forces if you cannot avoid an animal.
- Expect more than one. Deer often travel in groups. If one crosses, slow down and watch for others following.
- Buckle up and keep distance. Seat belts protect you if you do hit something, and extra following distance helps if the car ahead brakes suddenly.
What about deer whistles?
Car-mounted deer whistles are popular, but State Farm notes there is no scientific evidence that they work. Do not let one replace attentive driving.
What to Do If a Deer Is in Your Path
The instinct to swerve is strong, but it can turn a fender-bender into a far more serious crash with a tree, a ditch or oncoming traffic. Safety experts generally advise:
- Brake firmly and stay in your lane.
- Keep both hands on the wheel and maintain control.
- Sound your horn to encourage the animal to move.
- Do not swerve into another lane or off the road.
Modern automatic emergency braking can help in some situations, but IIHS has noted that not all systems are designed or verified to detect animals, so do not rely on technology to stop for you.
After a Collision: Step by Step
- Get to safety. Pull onto the shoulder if the car is drivable, turn on hazard lights and stay alert to traffic.
- Stay away from the animal. An injured deer can kick and cause serious injury. Do not try to move it.
- Call for help if needed. Contact police if anyone is hurt, the animal is blocking the road or your state requires a report. Some states have specific reporting rules for deer strikes.
- Document everything. Photograph the vehicle damage, the scene and any road signs.
- Check before driving. Look for fluid leaks, broken lights, a damaged hood latch or loose parts. If in doubt, have it towed.
How Insurance Usually Handles Animal Strikes
Hitting an animal is generally covered under comprehensive coverage, not collision, which is one reason comprehensive matters even on older cars in deer country. If you swerve to avoid an animal and hit a guardrail or another car instead, the claim is typically handled under collision coverage, which may carry a different deductible. Liability-only policies usually do not cover damage to your own car. Review your policy before the season starts and confirm your deductibles.
Prepare Your Car for Dark Fall Commutes
Visibility is your best defense against animal strikes, so make sure your car is ready for longer nights. Clean your headlight lenses; cloudy or yellowed plastic lenses reduce light output and can often be restored or replaced. Check that both low and high beams work and are properly aimed. Replace worn wiper blades and keep washer fluid topped up, because road spray and grime on the windshield make it harder to spot eyeshine at the roadside. If your vehicle has automatic high beams, learn how they work and when they switch off. Finally, keep your phone charged and carry a flashlight, reflective warning triangles or flares and a first-aid kit, so you are prepared if you ever need to stop on a dark rural shoulder after a collision.
FAQ
Which month has the most deer collisions?
November is consistently the peak month in insurance claim data, followed by October and December.
Is it better to hit the deer than to swerve?
In most situations, braking firmly in your lane is safer than swerving, which can lead to rollovers or crashes with other vehicles and fixed objects.
Will my rates go up after hitting a deer?
Comprehensive claims are generally treated differently from at-fault accidents, but pricing rules vary by insurer and state. Ask your agent.
