Maryland State Police are stepping up enforcement against truck parking on Interstate 83.

In a release Thursday, state police said they will begin strict enforcement of parking laws along I-83 between the Baltimore Beltway and the Pennsylvania state line starting Friday.

"Commercial vehicles parking on the shoulder of the highway cause extremely dangerous conditions,” Kimberly Smith, commander of the Maryland State Police Golden Ring Barrack, said in the release.

Except in cases of emergency, police will issue drivers citations that carry a $60 fine and no points.

Federal data show that tractor-trailers and other large commercial vehicles can contribute to crashes if they're parked on the shoulder, state police said. State officials said those drivers should access welcome centers, rest areas and weigh stations, or make other arrangements for safe parking off the highway.
