WINONA (AP) - The Minnesota State Patrol says it will step up enforcement of the state's "move over" law, named for a trooper who was struck and killed by a passing vehicle 15 years ago.

The added enforcement will take place Monday. It's the 15th anniversary of the death of Trooper Ted Foss, who was killed while making a traffic stop on Interstate 90 near Winona on Aug. 31, 2000.

The law named for Foss requires motorists to move a lane away from a stopped emergency vehicle with its lights on if there are two or more lanes going in the same direction.

No other troopers have been killed since the law's passage in 2001. The State Patrol has given out 435 citations and made 1,432 warnings so far this year.
