(CBS DETROIT) -   Two Michigan State Police troopers were injured after a motorist driving a truck hit a patrol car early Sunday. 

Police say it happened at 2:30 a.m. in the area of Interstate 96 and Joy Road.

The troopers, from the Metro South Post, were investigating a crash when a 20-year-old driving a Ford F-150 struck the patrol car. 

Both troopers were taken to the hospital to be treated for their injuries. The patrol car was significantly damaged.

Authorities say the 20-year-old, from Novi, was determined to be impaired and was arrested. 

Last month, a Michigan State Police trooper was killed after a crash on Interstate 75. Motor Carrier Officer Daniel Kerstetter had pulled a semi-truck over for a traffic violation when his vehicle was rear-ended by a 38-year-old woman driving a Ford Explorer. 

Kerstetter died from his injuries less than a week after the crash. The woman also died as a result of the crash.
