A Watertown man was listed in fair condition at Massachusetts General Hospital Wednesday after an accident where he became pinned under a garbage truck following a collision while he was riding his bike.

William Cress, who owns a home on Down Harbor Road in Katama, was transported to the Boston hospital by ambulance from the Martha's Vineyard Hospital Tuesday afternoon.

According to Edgartown police officer Michael Gazaille, a Bruno’s garbage truck was traveling on south on Katama Road when the driver made a left-hand turn onto a road across from Katama General Store.

The garbage truck and bike collided while Mr. Cress was riding a bike on the bike path, Officer Gazaille said. He was pinned under the truck for 15 to 20 minutes. The accident took place at about 12:45 p.m. Police later could not speak to the extent of injuries, but reports coming over the police scanner at the time of the accident indicated that Mr. Cress sustained serious injuries to his arms.

A spokesman for the Vineyard hospital later confirmed that the patient was being stabilized there. Medflight was grounded due to weather conditions and preparations were under way for a transfer by ambulance to a Boston hospital, spokesman Rachel Vanderhoop said.

The truck driver, Kevin O’Donnell from Oak Bluffs, was cited for failure to yield at an intersection, Officer Gazaille said. It appeared that Mr. O’Donnell did not see the biker coming up the bike path, he said, and the biker was likely cut off and went under the truck.
