The Indiana State Police is warning Hoosier drivers about potential fall seasonal hazards and the problems they can cause.

The Institute of Highway Safety says autumn typically brings a sharp increase in the amount of car versus animal insurance claims, with most of the claims involving deer. There are approximately 1.5 million deer collisions each year, according to the National Highway Traffic Safety Administration.

The Indians State Police says other factors such as wet leaves, rain, fog and frozen bridges can also pose safety risks.

Wet leaves can be as slippery as patches of ice, so drivers should be aware of leaf-covered roads and avoid hard braking.

To avoid the risks associated with fall driving, authorities recommend saving extra time for morning commutes, wearing a seatbelt, and paying attention to the “signs of fall.”
