Daylight saving time: The time change raises your risk of hitting deer on the road

Daylight saving time: The time change raises your risk of hitting deer on the road: Daylight saving time ends in the U.S. and Canada on Nov. 7, 2021, and most of us will be setting our clocks back an hour. There is a long-running debate about the benefit of the time change, given how it disrupts humans’ circadian rhythms, causing short-term stress and fatigue. Another risk accompanying the time change is on the roads: As more people drive at dusk during an active time of year for deer, the number of deer-vehicle accidents rises.
