PIKESVILLE, Md. (AP) — Maryland State Police say extra troopers will on duty over the July 4th weekend to help keep traffic moving smoothly and safely on the state’s highways.

The regular patrol force will be supplemented by more than 75 extra troopers working overtime over the weekend.

Troopers on interstates and state roads will concentrate on speeding, aggressive driving and drunken driving enforcement.

Each of the state’s 22 barracks will deploy at least one saturation patrol focused on identifying and arresting drunken
drivers in an area known for drunken driving arrests or crashes.

Over last year’s July 4th holiday, troopers arrested 163 drunken drivers and wrote more than 12,600 traffic citations and warnings.

More than two dozen troopers will help Baltimore police with July 4th events at the Inner Harbor.
