The Stone Temple Pilots and Velvet Revolver singer, who has a history of drug problems, was driving on a state highway on Nov. 21 when he had the accident.
The singer was arrested after an officer noticed he showed "signs of impairment" and failed field sobriety tests, according to a police report obtained by the celebrity site TMZ.com.
Weiland, 40, was taken to the Van Nuys Jail where he refused to take a blood or urine test, according to the police report. He was booked and released on $40,000 (Ђ27,275) bail. His next court appearance was set for Dec. 13.
Weiland's publicist said in a statement that the singer 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," she said.
