A release from BC Ferries said that at about 3:45 a.m. PT, a vehicle at the Descanso Bay terminal sped through the gate at the top of the loading trestle.
The vehicle then launched off the loading ramp and landed on the deck of the MV Quinsam, which was tied up in dock.
The car then continued speeding along and off the ferry deck, plunging into the water. Officials believe the vehicle then sank.
