A single-car accident that destroyed a sign on Route 1 in Rockport was the result of the driver falling asleep at the wheel, according to Rockport Police Officer Dana Smith.

Kimberly Olson-Hraba, 49, of St. George was driving south on Route 1 when she fell asleep and went off the road, police said. The 1990 Honda Civic she was driving hit large rocks at the base of a sign advertising PenBay Veterinary Associates at 599 Commercial St. Smith said the car bounced off the rocks and went through a fence that separates the front of the lot from a drop-off to a lawn in back.

“She went airborne,” said Smith. He said the airbag did not deploy.

Olson-Hraba complained of chest pain and was transported by Camden First Aid Association ambulance to Penobscot Bay Medical Center, where she was treated and released. The car was towed by All Directions Towing.

Smith said Olson-Hraba’s license had been under suspension since 2009.

Damage to the car was estimated at $7,000.

“Basically it’s a total,” said Smith. He said the sign was not severely damaged, but that the posts supporting the sign had snapped in the collision.
