AUGUSTA – Maine State Police plan to beef up patrols over the Memorial Day weekend, a spokesman said.

Additional state troopers and special enforcement officers have been tapped to work over the holiday.

The Maine State Police helicopter also will be used to spot aggressive drivers and identify trouble areas. Authorities will be targeting drunken drivers, speeders, and seat belt and child seat safety law violators, according to a news release Thursday.

The holiday marks the start of the summer tourist season when traffic normally picks up.

At the same time, 72 law enforcement agencies in Maine are taking part in a “click it or ticket” campaign this month, aimed at increasing seat belt use, the release said.

Neither the Lewiston nor Auburn police department is planning extra patrols over the weekend, spokesmen for those departments said.

Fifty-seven people have died on Maine roads this year compared to 54 at this time last year, according to Maine State Police Col. Patrick Fleming.
