Why You Shouldn’t ‘Veer for Deer’

Article summary

• Deer-vehicle collisions peak between October and December during mating season, with more than 1.5 million crashes occurring annually. Drivers face the greatest risk at dawn and dusk, particularly on rural roads near wooded areas, waterways and farmland.
• To reduce your risk, slow down in high-risk zones, use high beams when safe and scan both sides of the road for deer. If a collision is unavoidable, brake firmly and stay in your lane—swerving is often more dangerous than hitting the animal and can cause you to lose control or enter oncoming traffic.
• After a collision, move to a safe location, avoid approaching the deer and contact local law enforcement. Document the damage with photos and file a claim with your insurance provider, as deer collisions are typically covered under comprehensive auto insurance.

Every year, deer-vehicle collisions cause thousands of injuries, hundreds of fatalities and billions of dollars in damage across the United States. Deer can appear suddenly, especially during the fall mating season, making even experienced drivers vulnerable to a crash.

Knowing how to avoid deer collisions and react safely when one enters your path can help reduce your risk and protect everyone in your vehicle.

Why deer collisions increase in the fall

Fall is the most dangerous time of year for deer-related crashes. October through December is deer mating season, and as deer become more active, they create increased movement across roadways. Insurance claims involving animal collisions also peak during these months.

According to the Insurance Institute for Highway Safety (IIHS), more than 1.5 million deer-vehicle collisions occur annually in the United States, resulting in roughly $1 billion in vehicle damage and approximately 150 human fatalities. In fact, deaths from collisions with animals (mostly deer) increased from 89 in 1975 to 210 in 2024.

The shorter daylight hours in fall increase the risk because many commuters travel during dawn and dusk, when deer are most active. 

When and where deer are most active

Drivers should be especially alert:

• During dawn and dusk
• From October through December
• On rural roads bordered by woods or farmland
• Near waterways, parks and forests
• In locations marked with deer-crossing signs

If you see one deer, assume there are more nearby. Deer frequently travel in groups and often follow one another across roadways. 

How to avoid hitting a deer

1. Slow down in high-risk areas

Obey posted speed limits and reduce your speed in areas known for deer activity. Driving more slowly provides valuable reaction time if an animal suddenly enters the road.

2. Scan the road ahead

Continuously check both sides of the road, especially near wooded areas. At night, watch for the reflection of deer eyes in your headlights.

3. Use high beams when appropriate

When there is no oncoming traffic, high-beam headlights can improve visibility and help you spot animals farther ahead.

4. Stay alert for multiple deer

A single deer crossing often means additional deer are nearby. Continue scanning roadside areas even after the first animal has crossed.

5. Don't rely on deer whistles or gadgets

Research has found little evidence that deer whistles, reflectors or similar devices effectively prevent collisions. Maintaining awareness and reducing speed remain the most effective preventive measures.

6. If a deer runs onto the road, don't veer away from it

Your instinct may be to swerve, but this can be more dangerous than hitting the deer. Swerving can cause you to:

• Leave the roadway
• Strike a tree, guardrail or utility pole
• Enter oncoming traffic
• Lose control of your vehicle

Many serious injuries occur because drivers overcorrect or leave their lane while attempting to avoid an animal.

7. Brake firmly and stay in your lane

If a collision is unavoidable:

1. Brake firmly.
2. Maintain control of the steering wheel.
3. Stay in your lane.
4. Bring the vehicle to a controlled stop.

This approach typically results in less severe outcomes than sudden swerving maneuvers.

What to do after a deer collision

If you've been involved in a deer collision, safety should be your top priority. Once you've brought your vehicle to a safe stop, take the proper steps to protect yourself, report the incident and begin the insurance claims process.

1. Move to a safe location

If your vehicle is drivable, pull safely off the road and activate your hazard lights.

2. Don’t approach the deer

A deer that isn’t moving might be unconscious and could awaken at any moment, and an injured deer could kick, charge or thrash unpredictably. Do not attempt to move the animal yourself.

3. Contact authorities

Call local law enforcement to report the collision, especially if the animal is blocking traffic or there are injuries. The police report could also be helpful in your insurance claim.

4. Document the damage

Take photos of:

• Vehicle damage
• The surrounding area
• Any roadway hazards
• The deer you struck—without approaching it

This documentation can help support your insurance claim.

5. Contact your insurance company

Damage caused by hitting a deer is typically covered under comprehensive auto insurance coverage. Check your policy details for specific coverage information.
