(WISCONSIN) Drivers across Wisconsin face a higher risk on the road this time of year as deer activity picks up in late spring and early summer.
State transportation officials say May and June bring more deer near roadways as they search for places to give birth and young deer begin to separate from their mothers. That means more animals crossing roads — and more chances for crashes.
“Drivers should have their full attention on the road ahead to avoid deer crashes,” Wisconsin State Patrol Superintendent Tim Carnahan said. “Deer are unpredictable, often changing directions and freezing as they cross the road.”
Preliminary data shows nearly 18,000 crashes involving deer in Wisconsin last year. Those crashes killed six people and injured more than 700 others.
Motorcyclists face a much higher risk. In 2025, 223 crashes involved motorcycles, leading to four deaths and 80 serious injuries. More than a third of those crashes ended in death or serious injury, compared to less than 0.1% of crashes involving cars and light trucks.
Several counties saw especially high numbers. Waukesha County led the state with 1,010 deer crashes, followed by Washington, Sheboygan, Dane and St. Croix counties.
Safety officials say deer are most active around dawn and dusk, when visibility drops. They urge drivers to slow down, use headlights and stay alert — especially in areas where deer are known to cross.
If a deer steps into the road, experts say don’t swerve suddenly. Brake firmly and stay in your lane to avoid losing control. And if one deer crosses, there may be more close behind.
After a crash, drivers should move their vehicle off the road if they can. Call 911 if anyone is hurt or if the deer is blocking traffic. If not, report the crash to local law enforcement and stay inside your vehicle while waiting for help.
Officials also warn drivers not to approach or try to move an injured deer.
