The Colorado State Patrol has identified several high-risk corridors for wildlife vehicle collisions following a year in which troopers responded to more than 3,900 such incidents. These crashes have seen a steady increase since 2021, driven in part by climate-related factors.

Why it matters

Drought conditions and hot weather have intensified the overlap between human traffic and wildlife migration. Increased animal movement to lower elevations during mating seasons creates consistent hazards for motorists on major state routes.

Troopers recorded over 3,900 wildlife vehicle crashes in 2025 alone. White-tailed deer and elk remain the species most frequently struck by vehicles, alongside pronghorn, bear, and marmots.

The players

Colorado State Patrol

This law enforcement agency is responsible for maintaining public safety on Colorado highways and tracking traffic incident trends.

The details

High-risk zones identified by officials include Interstate 25, Interstate 70, US 285, and Highways 24, 40, 50, and 160. Wildlife are particularly prone to crossing roads at high frequencies while distracted as they migrate to lower elevations for mating seasons.

Timeline

  1. 2021 marked the start of a steady increase in wildlife vehicle collisions.

  2. Troopers responded to over 3,900 crashes involving wildlife in 2025.

  3. Autumn serves as the most active time for wildlife vehicle collisions.

Culture Shift

This data reflects a long-term shift in human-wildlife interaction patterns caused by climate-driven habitat changes. The steady rise in collisions underscores how environmental stresses alter the intersection of regional infrastructure and migratory behavior.

Drivers in Colorado should exercise extreme caution on high-risk routes like I-25 and I-70, especially during autumn. Increased vigilance during dawn and dusk can help motorists avoid wildlife that may cross roads while migrating.

The takeaway

Motorists should reduce speeds in identified high-risk zones and remain alert for animal activity, particularly during migration seasons. Planning travel during daylight hours can further improve reaction times and safety for all road users.
