SAN BRUNO, Calif. -- Think autonomous cars are programmed to follow traffic laws? Think again.

San Bruno, California police officers pulled over a Waymo car with no driver Friday night while conducting a crackdown on driving under the influence.

Police said the Waymo made an illegal U-turn in front of them.

The department shared photos of the traffic stop.

No citation was issued because there was no driver to cite.

That'll change next July when a new California law takes effect allowing law enforcement to issue citations to operators of driverless vehicles.
