Two accidents involving intoxicated drivers occupied police in Edgartown and Chilmark over the weekend.

In Edgartown, police chief Bruce McNamee reported a two-car collision on Barnes Road Saturday evening. He said the call came in at about 7:30 p.m. When police arrived, both operators, a man and a woman, were standing outside their vehicles. The chief said the woman had fallen asleep while driving and drifted into the opposite lane. According to police she was transported to the Martha’s Vineyard Hospital for treatment of minor injuries, and later charged with operating under the influence of alcohol (third offense), negligent operation of a motor vehicle, operation of a motor vehicle after a license suspension and marked lanes violation. The operator of the other vehicle was not injured, the chief said.

In Chilmark, police chief Jonathan Klarén reported a two-car collision on Friday afternoon at about 1 p.m. He said one car struck an oncoming vehicle on South Road. No one was injured, and there was minor damage to the vehicles. A 56-year-old Edgartown woman was charged with operating under the influence of alcohol (second offense), negligent operation of a motor vehicle, leaving the scene of a motor vehicle accident with property damage and failure to stay within marked lanes.

Police chief Matthew Mincone of West Tisbury and Chief Randhi Belain in Aquinnah both reported no serious weekend incidents.

Lieut. Timothy Williamson of Oak Bluffs also said it was a quiet weekend in his town aside from weather related residential alarms.

Tisbury police reported no serious weekend incidents, but Det. Max Sherman said Tisbury officers would be on hand once again at Stop & Shop the day before Thanksgiving. Officers will help customers carry food to their cars and run grocery carts. They will collect donations for the Island Food Pantry as well.

In Edgartown Chief McNamee said there would be a gathering Friday at noon at the fire department museum to commend the officers who saved a man’s life after he lost consciousness and stopped breathing while driving a car in Edgartown last month.
