Via TMZ

John Stamos was booked for DUI Friday night in Beverly Hills, and was allegedly so out of it ... police sent him straight to a hospital.

Law enforcement sources tell TMZ ... Bev Hills officers responded to a call around 7:45 PM of a silver Mercedes driving erratically, and when cops stopped the vehicle ... they felt Stamos needed immediate medical attention. He was driving by himself.

Officers handcuffed Stamos at the scene, and then paramedics transported him to a hospital.

Police followed, and cited him for misdemeanor DUI while he was getting treatment.
