If a deer runs in front of your car, brake firmly, steer straight and stay in your lane. Do not swerve. US state driver manuals and DMVs give this same core advice, because swerving can put you into oncoming traffic, a tree or a ditch. This guide is for new US drivers. It covers when animal crashes peak, how to lower the risk, and what to do and report after hitting an animal.
Key facts
- Do: brake firmly and steer straight. Don’t: swerve. (New York DMV; Maine Driver’s License Manual.)
- Deer dominate: a Federal Highway Administration (FHWA) report to Congress says the vast majority of recorded US animal crashes involve deer.
- Peak season: fall, especially October and November, with a smaller spring peak in May and June (FHWA, 2008).
- Peak times: around dawn and dusk. FHWA gives roughly 5 to 8 a.m. and 4 p.m. to midnight.
- Scale: FHWA estimated 1 to 2 million wildlife-vehicle collisions a year. That estimate dates from 2008, so treat it as a rough guide.
What to do if a deer runs in front of your car
- Brake firmly. Keep your foot down. Modern anti-lock brakes let you brake hard and still steer.
- Steer straight. Keep the car in your lane. The New York DMV warns that swerving can cause a collision with another vehicle, a tree, a pole or another object.
- Sound the horn if there is time. It may move the animal along.
- If a crash cannot be avoided, keep braking in a straight line. The Maine manual adds a technique for large animals like moose: let up on the brake just before impact, so the front of the car rises slightly, and duck down to protect yourself from glass.
- Expect more. Deer often travel in groups. If one crosses, slow down and watch for the next.
Why swerving is the bigger danger
The car is built to protect you in a frontal impact. A sudden swerve at speed can make you lose control, cross the center line or leave the road. For a deer-sized animal, a controlled straight-line stop is the safer choice for you and other drivers. Moose are a special case because of their height. See avoiding moose and deer collisions in Maine and driving in Alaska’s moose country.
When are animal crashes most likely?
| Factor | Higher risk | Why |
|---|---|---|
| Season | October and November, then May and June | Deer breeding season in the fall means more movement. The Maine manual says moose crashes peak in May and June. |
| Time of day | Dawn and dusk into the night | Deer and other large animals are most active then, and visibility is poor. |
| Location | Rural two-lane roads, wooded edges, near fields and water | Animals cross between feeding and cover areas. |
| Signs | Deer or wildlife crossing signs | States place them where crashes are a known problem. |
How to reduce the risk
- Slow down at night on rural roads, so you can stop within the distance your headlights show.
- Use high beams when there is no oncoming traffic or car ahead. The Maine manual says high beams let you see twice as far as low beams.
- Scan the road edges, not only the lane ahead. Deer eyes often reflect your headlights. Moose eyes usually sit above the beam.
- Take crossing signs seriously, especially in fall at dusk.
- Wear your seat belt. It is your main protection if you do hit something.

What to do after hitting a deer or other animal
- Pull over safely if the car can be driven. Turn on your hazard lights.
- Stay in or near the car. Do not approach the animal. An injured deer can kick, and a moose can attack.
- Call the police or the local emergency number if the animal or debris blocks the road, anyone is hurt, or the car cannot be driven. The California Driver Handbook says to call the nearest humane society or law enforcement if you kill or injure an animal, and not to try to move an injured animal.
- Take photos of the car, the scene and the road for your insurer.
- Check the car before driving on. Look for leaks, broken lights and a damaged hood latch.
- Report the crash if your state requires it. See below.
Do you have to report hitting a deer?
It depends on your state and the damage. Reporting rules are set by each state and usually turn on injuries and the cost of the damage, not on what you hit. One example: in California, every driver must file a Form SR 1 with the DMV within 10 days if a collision caused more than $1,000 in property damage or anyone was injured or killed. Other states use different thresholds and forms, so check your state’s driver manual. The general steps after any crash are in what to do after a car crash in the US.
Can you keep the deer? Some states allow it with a permit from the wildlife agency, and others do not. Never take an animal without checking with the state wildlife agency or the officer at the scene.
Common questions
Should I swerve to avoid a deer?
No. Brake firmly and stay in your lane. Swerving is what turns many animal crashes into serious ones.
Do deer whistles work?
None of the official sources used here recommends them. Rely on speed, scanning and high beams instead.
Is hitting a deer covered by insurance?
It depends on your policy. Insurers often handle an animal strike under a different part of the policy from a crash with another car, and the minimum insurance most states require may not pay for damage to your own car. Check your policy, and call your insurer after the crash.
What time of year should I be most careful?
Fall, especially October and November, around dawn and dusk.
What if a deer is standing in the road?
Slow down or stop, use your horn, and wait for it to move. Do not try to drive around a large animal, and do not get out.
Can animal crashes come up on the permit test?
Yes, in some states. Maine’s manual includes moose and deer in its practice questions, for example. Read the animal section of your state manual.
