EDISON - Officials are warning motorists in New Jersey to be on the lookout for deer.

State Fish and Wildlife Deputy Director Lawrence Herrighty says it's the beginning of breeding season when male deer start chasing does.

Herrighty says deer are most active during dawn and dusk.

The Highway Loss Data Institute and wildlife officials say collisions increase in late September and peak in November.

The state Transportation Department removed 6,028 deer carcasses from roads in 2009.

Deer collisions have reportedly grown nationwide by 21 percent in the past five years.
