Deer and the Clocks

Read it instead

This Sunday, the clocks go back an hour.

Your drive home moves into the dark. Right as deer mating season heats up.

In November, Massachusetts drivers hit a deer about once an hour.

And the worst hours are right after sunset.

Nationally: 14 times more deer crashes two hours after sunset than before.

Starting Monday, that's your commute.

Across the US, deer crashes jump 16% the week after the clocks change.

Slow down at dusk. If one deer crosses, expect more.

Brake, don't swerve.

Deer mating season runs into early December. Slow down at dawn and dusk; if one deer crosses, more may follow.
