COLUMBUS, Ohio (AP) — Ohio’s State Highway Patrol and state police in five other states are focusing on enforcement of the Move Over law.

The law requires drivers approaching any vehicles with flashing or rotating lights that are parked on the roadside to move over to an adjacent lane. Motorists should slow down and proceed with caution if moving over isn’t possible due to traffic or weather conditions or lack of a second lane.

The safety effort began Sunday will end at 11:59 a.m. July 28. It includes state police in Indiana, Kentucky, Michigan, Pennsylvania and West Virginia.

From 2013-2017, Ohio patrol cruisers were involved in 58 crashes that appear to be related to the Move Over law. The crashes resulted in the deaths of two civilians and injured 34 civilians and 24 officers.
