Authorities received a call from witnesses who saw a car go over the side shortly before 10 a.m. When deputies arrived, they found the red convertible about 300 feet over the side. The driver was declared dead at the scene.
Rescue crews searched the area for other possible victims. They said the airbag on the passenger's side deployed, which may indicate that someone else was sitting in the car, but no other victims were found.
Malibu Canyon Road was shut down temporarily in both directions due to the search, from Piuma Road to the north and Pacific Coast Highway to the south.
The cause of the crash has not yet been determined.
