(Harrisburg) -- Pennsylvania ranks as one of the worst states for car and deer collisions. In spring, the risk for such crashes increases. That's because yearling deer are usually on the move this time of year, after their mothers kick them out to prepare to give birth to new fawns. Jerry Feaser, spokesman for the state Game Commission, says deer collisions can happen in urban and suburban areas. "It's not uncommon as you use the Pennsylvania Turnpike or any of our interstates to see deer on the side of the roads taking advantage of the vegetation," he says. "Now, many of those deer are more accustomed to the vehicles because they live in those areas. But still you'll have these young yearlings that may accidentally get out into the highway, cross the highway." Feaser says drivers need to be more watchful for the animals on the roads this time of year, especially after dark and before sunrise. He adds Pennsylvania residents are permitted to claim deer carcasses for venison as long as they call the regional commission office to obtain a free permit number.
