LINCOLN, Maine — Three accidents in the span of a few minutes Sunday compelled police to warn motorists Monday to keep an eye on the weather and the roads.

“As we are coming into cold weather, coming into storms, we have to remember that freezing rain is a part of what we get,” Public Safety Director Daniel Summers said Monday. “People should take care, take precautions to see that they don’t get hurt.”

Officer John Walsh was called to Transalpine Road near Rocky Brook Road at about 9 a.m. Sunday for a reported rollover accident. Walsh found a Ford F-150 pickup truck that slid across the opposite lane into a snow embankment and tipped onto its driver’s side, Summers said.

Driver William Kettle, 47, of Lincoln was unhurt but needed help from firefighters, who held open the passenger-side door while he climbed out of the vehicle, Summers said. Kettle’s vehicle had significant damage on the driver’s side.

Police believe the combination of rainfall and cold temperatures formed black ice on the roads. Two other accidents, one on Transalpine Road and another on Enfield Road near the town line, occurred while Walsh was tending to Kettle, Summers said. Both vehicles slid off the road.

Kettle was not charged for his accident. The other two accidents were minor, Summers said.

“We don’t believe he was speeding — just driving too fast for conditions,” Summers said.

Drivers, Summers said, should take several winter precautions. They should wear safety belts, check weather and road conditions before getting behind the wheel, put snow tires or studded tires on their vehicles and keep emergency equipment such as reflectors and flashlights in their vehicles.

“Just having a seat belt on can make a big difference,” Summers said. “He [Kettle] did, and he did all right.”
