A trooper is OK after someone lost control and rear-ended him Tuesday morning.
The crash shut down M-72 in Kalkaska County for several hours.
It happened at M-72 and Lake Valley Road M-72.
The road is now back open.
Troopers say a driver was going too fast for the slick and foggy conditions.
He did not have time to stop and smashed into the back of this cruiser.
