ORONO — Police credit seat belts for saving a West Enfield couple from serious injury Tuesday morning when their car went off Interstate 95 near the Kelly Road exit and rolled over three times.

Priscilla Reynolds, 59, and her husband, Gerald, 63, were returning home from a trip to Connecticut when Mrs. Reynolds fell asleep at the wheel at about 9 a.m., according to Trooper Gary Jordan of the Maine State Police.

Jordan said the 1995 Buick four-door sedan drifted into the breakdown lane of the northbound lane of I-95 before Priscilla Reynolds woke up and unsuccessfully attempted to right the car. She apparently overcorrected, causing the car to flip over three times.

Both were taken to St. Joseph Hospital in Bangor and were treated and released, according to a nursing supervisor.

Trooper Jordan said both the driver- and passenger-side airbags in the car deployed, but it was the seat belts that kept the couple safe through all the rollovers.

A man driving behind the Reynolds vehicle witnessed the accident and quickly called for help from his car phone. Police and emergency personnel were on the scene in about five minutes, according to Jordan.

Mrs. Reynolds told the officer she and her husband had left Connecticut shortly after midnight and were attempting to drive straight through when she fell asleep.
