Earlier Sunsets Mean More Bears on Colorado Roads This Fall

Drivers across Colorado should expect to see more animals on their commutes starting Sunday. The end of daylight saving time brings earlier sunsets, which overlap with the time of day when wildlife is most active. This shift increases the likelihood of encounters during the morning and evening rush hours.

Bridget O’Rourke, the statewide public information officer for Colorado Parks and Wildlife, noted that the clock change makes it darker sooner. Animals are currently moving to lower elevations to escape colder temperatures at higher altitudes. This migration often forces them to cross roads that are busy with traffic.

October through December typically see the highest volume of wildlife-related crashes in the state. In 2025, the Colorado State Patrol responded to 3,811 incidents involving animals. O’Rourke said that wildlife use roads to find food, water, or shelter, and their movement is driven by the need to prepare for winter.

This year marks a record high for bear activity in Colorado. O’Rourke stated that bears are walking along roadways during dawn and dusk to eat as much as possible before the cold season sets in. She warned that Coloradans will likely encounter more bears on roads this year than in previous seasons.

To stay safe, Colorado Parks and Wildlife recommends that drivers slow down in known wildlife crossing areas. Drivers should scan the road sides for movement and allow animals time to cross. The agency advises that if a driver sees one animal, they should expect to see others nearby.

O’Rourke emphasized that safety must be the priority for the driver, other motorists, and the animal. If a collision occurs, drivers should contact the Colorado State Patrol for assistance. The agency also points to existing wildlife crossings, including overpasses and underpasses, as key infrastructure for managing these interactions.

Beginning in January 2027, an optional $5 fee will be available on vehicle registrations to fund wildlife crossing projects. O’Rourke described Colorado as a leader in considering migration patterns during new road construction. The state will use these funds to support infrastructure that helps animals cross safely.
