Driver flies off San Francisco highway in horror crash
This is the horrifying moment an out-of-control car drove off a main highway in San Francisco.
The dashcam footage, captured on January 26, shows the vehicle changing lanes whilst driving along the road at high speed.
The car then seems to lose control and crashes into a traffic sign as it plunges off the road.
The witness writes: ''It appeared that the driver was swaying side to side in the driver's seat prior to the crash."
''Prior to the crash you can see the car make a weird and illegal lane change.''
