California: An unclothed woman caused a commotion on one of the most congested bridges in the country when she started shooting a gun on Tuesday.

The California Highway Patrol said the strange incident happened during peak traffic on the bridge that connects San Francisco and Oakland on the I-80 highway, around 4:40 p.m.

A motorist reported to 911 that another driver had pointed a gun at them on the span that crosses the bay, according to the police.

The woman then halted her car in her lane, stepped out with a knife and screamed at other motorists, cops said.

She then drove to Oakland, but stopped again at a toll booth and got out of the car — this time armed with a gun and without any clothes, officers told The Post.

The woman, who was not identified, then spun around and shot at random at the cars that were stuck behind her, according to the police.

Police said a video clip showed her walking on the side of the road and firing her gun into the sky before officers got there and persuaded her to put down her weapon, arresting her without any trouble.

Amazingly, no one was hurt, and the reason for the woman’s actions was unknown.
