CHARLOTTE, N.C. -- The Department of Transportation is issuing a warning as vehicle collisions involving deer have been on the rise in recent years and as we enter hunting and mating season, officials say they'll be on the roads even more over the next few months.

Most of the time, we see them in fields, or in our yards. But on the road, they're a serious threat and NCDOT says it got worse from 2013-2015.

"In that two-year stretch a dozen people lost their lives," Jen Thompson said. "And damage to your car we've calculated over $140 million. So it's a very serious problem."

Corey Patterson at Maaco Collision Repair says from October to December they see a ton of cars that are in collisions with deer.

"Estimates are up right now," Patterson said. "I've seen about 5 or 6 already this week."

Including this car, which they got just yesterday.

"As you can see it landed on the windshield and caused the customer to spin and they actually went into a pole," Patterson said.

Repairs for crashes like this could cost you as much as $4,000 or $5,000. And with daylight savings time ending Sunday, most of us will be driving more often when it's dark. Thompson says to keep your high beams on as much as possible.

"You'll get a reflection of their eyes in your headlights," Thompson said. "Obviously increase your following distance and slow down, because they're more active when it's tougher for us to see."

Thompson also says it's not always a good idea to swerve because you can go off the road, and put yourself in even more danger.

"You can see how much damage these things can cause," Patterson said.
