Fullerton police Lt. Craig Brower says officers stopped 32-year-old Shante (Shahn-taye) Broadus of Sherman Oaks about 12:15 a.m. Saturday and took her to jail. She was cited and then released pending a court appearance.
Brower says nobody else was in the car but he didn't have any other details.
Broadus and Snoop Dogg - whose real name is Calvin Broadus Jr. - were married in 1997 and have three children.
A message left with Snoop Dogg's publicist was not immediately returned.
