"Keep seasons in mind
Collisions can also happen any time of year – after all, deer don’t hibernate, Adams points out. But two times of year are typically more high risk.
Adams said the first one is spring. That’s fawning time, and “deer are way more active around roads,” he said.
“When a doe is having her fawn, the does become extremely territorial of those areas. … What happens is deer get spread out a lot more on the landscape, which means that they’re more apt to, you know, be near a road.”
But autumn is the season most fraught with danger, Adams said, “and the majority of that occurs in November. During that time, deer greatly increase their daily movement patterns,” he said, especially the bucks.Research from State Farm insurance company also highlights November as the most likely month of the year to have a collision with an animal."
That's okay media source.....
it's still politically correct to say what it it. They rut, or breeding season 
It's that time of year that makes working 10a to 6:30p real interesting here in Ohio. Normally a couple days a week I have to work in a more remote area and it's nothing to have the deer standing right beside the road when winding through. Gets a little unnerving at times.
