"21804 of the California Vehicle Code requires any vehicle who is entering the highway from private properties, such as a driveway, to yield to oncoming traffic that's close enough to constitute an immediate hazard," said Sgt. Brian Pennings with the California Highway Patrol.
"So when you are making your U-turn from that designated turning point in the center of the road, whether it be a two-way left turn lane or a left turn pocket, that vehicle coming out of the driveway technically has to yield the right of way to you because you are established in the roadway," he explained.
