A man riding a scooter on 101 in San Francisco was killed Wednesday night, when he fell from the the highway to the street far below.

According to California Highway Patrol spokesperson Officer Vu Williams, the scooter rider was "making a sweeping left turn" onto 101 north just south of the Ninth Street exit at 11:23 p.m. Wednesday.

As he made the turn on this elevated stretch of roadway, he apparently lost control and struck the guardrail. The man then fell from the highway to the street below, a distance of around 40 feet.

The man, who has yet to be publicly identified by the San Francisco Medical Examiner's office and was described only as "in his 30s," was pronounced dead at the scene, Williams says.

No other vehicles were involved in the crash, and no other damage or injuries were reported as a result of his fall, Williams says.
