Christopher Moore, 20, was pulled over around 3:30 a.m. Thursday on a Calabasas road leading to a gated community where Bieber lives, said Los Angeles County Sheriff's Department spokesman Steve Whitmore.
Moore was driving a 2012 Fisker registered to the pop star and going between 60 and 70 mph in an area that has a 30 mph speed limit because of construction, authorities said.
Investigators think Moore might have been under the influence of marijuana. Bail was set at $5,000 for the misdemeanor offense.
Moore is signed to Lil Wayne's Young Money Entertainment label imprint. An email seeking comment was sent to his record label.
