Marked Virginia State Police cars are getting a small makeover with a big message.
All cars will get new bumper stickers to remind people to move over or slow down when they see emergency lights on the side of the road.
Since 2003, 138 on-duty police officers have been hit and killed on America's roads.
The most recent killed in Virginia was Trooper Andrew Fox of Pulaski.
State Police say drivers have become more familiar with the Commonwealth's Move Over Law, but it's still not safe out there.
"It's very dangerous not only for police officers but you also have rescue, fire, tow-truck operators and VDOT workers out there on the roads," said State Police Sergeant Bob Carpentieri.
The bumper stickers are paid for by a $3,500 grant from the Virginia State Police Association.
