Deer-vehicle collisions in Pennsylvania
In shortPennsylvania drivers have about a 1 in 64 chance of an animal collision in a year, the fourth-highest odds in the country, and Pennsylvania leads the nation in animal-collision claims, about 141,000 between July 2025 and June 2026, according to State Farm data. Most involve deer, and the risk peaks in October, November and December.
Why is fall the most dangerous season?
Fall is breeding season. Deer move more, move at dawn and dusk, and cross roads without warning.
What can drivers do?
- Slow down at dawn and dusk near woods and fields.
- Where you see one deer, expect more.
- Use high beams when the road is clear.
- Brake firmly and stay in your lane. Swerving often causes worse crashes.
What can landowners and townships do?
Collisions cluster where deer numbers are high and roads cut through their range. Managing deer on the properties along those roads, through DMAP, controlled archery and a deer count, is one of the most direct ways to make roads safer.
