Illinois transportation officials are warning motorists to beware of more active deer as mating season begins.
The Illinois Department of Transportation says about 40 percent of crashes in Illinois last year that involved deer happened in October, November and December.
There were about 14,700 motor vehicle crashes involving deer in 2016.
About 1,000 fewer than in 2015.
Deer-vehicle accidents last year caused five fatalities and about 580 injuries.
