Authorities say whenever you see an emergency vehicle on the side of the road, slow down and or move over.  It’s the law.  ” It’s a dangerous thing to be sitting on the side of the road. For law enforcement it’s very dangerous. You have people not paying attention, you have drunk drivers driving down the highway, you have people falling asleep, so be very aware of what is coming up behind you,” said Sgt Nothum.

Investigators say at this point are not sure what charges the driver might face because the cause of the accident remains under investigation.
