TMZ has learned that rocker Scott Weiland has been arrested, again, for DUI. Shocker, we know.

The Stone Temple Pilots and Velvet Revolver singer was driving on an L.A. highway around 6:15 PM on November 21 when he crashed his car. While the California Highway Patrol was investigating the non-injury wreck, they noticed Weiland appeared to be impaired. (Um ... ya think?) According to the police report, Weiland failed sobriety tests and refused to take a blood or urine test. He was booked for "driving under the influence of a drug. "

He was released on $40,000 bail and will be back in court on December 13.

Weiland is no stranger to run-ins with the law. He was busted for buying crack in 1995, domestic violence in 2001, DUI on his birthday in 2003, and as TMZ first reported, allegedly trashed a hotel room while brawling with his wife. His wife later issued a statement saying her hubby was "simply trying to help calm me down."

A rep for Weiland said in a statement that the signer was involved in a "minor accident," but denies he was driving under the influence. "Scott was not driving under the influence of a drug, legal or illegal," Kristine Ashton-Magnuson said. "He voluntarily took a breathalyzer test which the defense believes registers well within the legal limit. He is anxious to get to court ... and clear this matter up."
