Los Angeles ? George Clooney suffered a broken rib and some scrapes on Friday when the motorcycle he and a friend were riding collided with a car as the actor tried to pass the other vehicle, authorities said.

Weehawken Police Sgt. Sean Kelly said the collision occurred at 3:30 p.m. as Clooney and friend Sarah Larson were traveling north on Boulevard East and sped up to pass on the right a 1999 Mazda Millenia that was preparing to make a right turn.

Kelly said it is not known if the driver of the other vehicle, who has not been identified, had used his turn signal.

The 46-year-old actor was treated at Palisades Medical Center in North Bergen and released, spokesman Stan Rosenfield said in a statement.

Larson suffered a broken foot. Both she and Clooney were wearing helmets, Kelly said.
