State Police are urging drivers to slow down and move over when they see an emergency vehicle on the roadside. 
They are reporting that in less than a week three stopped trooper cars have been hit from behind during traffic stops causing injuries to four different troopers.

The 'move over' law also means that vehicles reduce speed and move for any hazard vehicle that has amber warning lights like tow trucks and snow plows.
