At dusk, why is there an increased risk of hitting a deer?

The increased risk of hitting a deer at dusk is closely linked to the behavior of deer during this time. As daylight fades, deer become more active, particularly as they search for food. Dusk is when they typically venture out from their bedding areas to graze, making them more likely to cross roads. This heightened activity during low light conditions significantly contributes to the risk of encounters with vehicles.

While it’s true that deer may also wander close to roads and are more active during mating season, the specific reason for the increased risk at dusk is their feeding behavior combined with the lower visibility that comes with twilight. Reduced visibility can make it harder for drivers to see deer on or near the roadway until they are very close, increasing the likelihood of a collision. Thus, the behavior of deer in searching for food during this time is a key factor in the heightened risk.
