We've learned the ex-front man for the 80's hairband Warrant -- Jani Lane -- was officially charged with DUI and hit-and-run.
The 45-year-old singer was busted on June 17th when he allegedly hit a parked car in Los Angeles. Lane refused to take a sobriety test.
If convicted, Lane could get 6 months in the slammer and a $1,000 fine.
