The Minnesota State Patrol says a trooper was seriously injured in a two-vehicle crash in Lakeville.
The agency says a car driving at a high speed on Interstate 35 on Tuesday afternoon veered off the road, went through the freeway fence and struck the trooper's vehicle head-on.
Thirty-five-year-old Sgt. Mike Krukowski, of Oakdale, was taken to a Minneapolis hospital with injuries the patrol says are serious but not life-threatening.
The driver of the other vehicle also was seriously hurt.
Authorities are continuing to investigate.
