Maine State Police are cracking down on motorists who aren’t buckling up. State police issued more than 3,000 seat belts summonses and warnings to motorists in the first three months of the year. The chief of the state police had asked troopers to make seat belt priority, resulting in 2,478 summonses and 2,549 warnings being issued from January through March. During a similar effort last summer, troopers issued 769 summonses and 1,717 warnings. Col. Robert Williams, head of the state police, says about half of those killed on Maine roads this year weren’t buckled up.
