A trucker hauling a load of Volkswagen cars drove his cab and several cars into San Diego Bay after blacking out at a marine terminal, authorities said.

The unidentified driver suffered some kind of medical emergency and drove off a pier at the terminal Saturday afternoon, said fire department Capt.Sergio Mora.

Mora said the driver — believed to be in his 40s — regained consciousness underwater and swam about 13 feet to the surface, where dock workers helped him out.

He was taken to a hospital in good condition.

The driver was bound for Los Angeles with his semitrailer load of 2008 Volkswagens of various models. Three of the VWs fell into the bay.
