How to Avoid Deer Collisions During Wisconsin’s Fall Season

Autumn in Wisconsin brings crisp air, colorful leaves, and unfortunately, an increased risk of deer collisions. Wisconsin consistently ranks among the top ten states for deer-vehicle crashes, and fall is the most dangerous season of all.

According to the Wisconsin Department of Transportation (WisDOT), there were more than 16,000 reported deer crashes in 2024, resulting in over 500 injuries and nine fatalities. Experts believe the actual number is even higher since many minor collisions go unreported.

The majority of these crashes occur between October and December, when deer are most active during their annual mating season. Collisions can happen anywhere, but rural highways, wooded roads, and suburban areas near fields are the most common hotspots.

Why Deer Collisions Spike in the Fall

Deer collisions increase dramatically during autumn due to a combination of biological and environmental factors:

• Mating season (the rut): Deer are more active and less cautious during mating season, which typically peaks in November.
• Changing daylight: Shorter days mean more commuters are driving at dawn and dusk, the times when deer are most active.
• Harvest season: Farmers clearing fields push deer toward nearby roads and wooded areas.
• Population growth: Wisconsin’s deer population remains strong, with estimates exceeding 1.6 million deer statewide.

This seasonal pattern means that even cautious drivers can find themselves face-to-face with a deer suddenly crossing the road.

Where and When Deer Collisions Happen Most Often

Certain parts of Wisconsin consistently see higher deer collision rates. According to WisDOT data, the counties with the most crashes in recent years include Dane, Waukesha, Shawano, Washington, and Fond du Lac.

Most collisions occur during the early morning (5–7 a.m.) and evening hours (6–9 p.m.). These times coincide with both heavy commuter traffic and peak deer movement.

Drivers traveling on two-lane rural highways are at the highest risk, especially near wooded corridors or farmland where visibility is limited.

How to Avoid Hitting a Deer

While not all collisions can be avoided, there are several proven ways to reduce your risk:

1. Stay alert at dawn and dusk. Deer are crepuscular, meaning they are most active during low-light hours.
2. Use high beams when possible. They help you spot deer earlier and can reflect off their eyes from a distance.
3. Watch for more than one deer. Deer often travel in groups, so where you see one, more are likely nearby.
4. Do not swerve. Sudden swerving can cause you to lose control and hit another vehicle or obstacle.
5. Brake firmly and stay in your lane. Maintaining control of your vehicle is the best way to minimize injuries.
6. Heed deer crossing signs. They are placed in high-risk areas based on historical crash data.
7. Slow down in wooded or rural areas. Reducing speed gives you more time to react.
8. Avoid distractions. Keep your phone down and focus on the road, especially in known deer zones.

Even the best drivers can experience a collision, but taking these precautions greatly improves your chances of avoiding one.

What to Do If You Hit a Deer

If a deer collision does occur, stay calm and take the following steps:

1. Pull over safely. Move your vehicle to the shoulder and turn on your hazard lights.
2. Check for injuries. Call 911 immediately if anyone is hurt.
3. Do not approach the deer. Injured animals can be unpredictable and dangerous.
4. Report the crash. In Wisconsin, you must report any crash involving injury, death, or significant property damage to law enforcement.
5. Document the scene. Take photos of the vehicle, road conditions, and damage for your insurance claim.
6. Contact your insurance company. Deer collisions are typically covered under comprehensive coverage, not collision coverage.

If another driver’s negligence contributed to the crash such as tailgating, distracted driving, or unsafe passing you may have grounds for a legal claim beyond a standard insurance payout.

Injuries Common in Deer-Related Crashes

Deer collisions can cause serious injuries, especially when drivers lose control or swerve into oncoming traffic. Common injuries include:

• Whiplash and neck injuries from sudden braking or impact.
• Head trauma if airbags deploy or the vehicle rolls over.
• Fractures and soft-tissue injuries from seat belt restraint or secondary collisions.
• Spinal injuries caused by high-speed impacts.

Motorcyclists face especially severe outcomes. The Wisconsin DOT reports that nearly half of all fatal deer collisions involve motorcycles, where even minor impacts can be deadly.

Who Is Liable After a Deer Collision

Most deer crashes are considered “no-fault” incidents, meaning the driver is not legally responsible for hitting a wild animal. However, there may be some extremely limited circumstances where another party’s negligence may be involved, such as where a driver in front of you was speeding or was otherwise negligent in managing or controlling their vehicle before hitting the deer such that it caused you to collide with the negligent driver

If you are unsure if you have an injury case arising out of an impact with a deer, an experienced attorney can give you guidance.

Seeking Compensation After a Deer Collision

In Wisconsin, drivers injured in deer-related crashes may be able to recover compensation through one or more avenues:

• Insurance claims: If you have comprehensive coverage in your insurance policy, that will typically apply to deer impacts, while medical payments coverage can help with medical bills.
• Personal injury claims: If another driver or entity contributed to the accident, you may seek damages for medical expenses, lost wages, and pain and suffering.

Because every situation is different, consulting a lawyer can help determine the best path forward and ensure all potential claims are pursued.

Preventing Deer Collisions in Wisconsin

Wisconsin continues to take steps to reduce the number of deer-vehicle collisions statewide. Efforts include:

• Installing deer fencing and wildlife crossings in high-risk areas.
• Implementing public awareness campaigns each fall to remind drivers to slow down.
• Collaborating with local governments and hunting groups to manage deer populations.

Drivers can do their part by staying attentive and recognizing that deer movement patterns change with the seasons. Prevention remains the most effective strategy.
