The California Highway Patrol arrested Klein on June 16 after he was spotted weaving across lanes on the westbound 101 Freeway in Sherman Oaks.
In 2005, Klein was fined $1,800 and ordered to perform 150 hours of community service after pleading guilty to a misdemeanor drunken driving charge in San Diego County.
Klein played the character of Chris "Oz" Ostreicher in 1999's "American Pie" and in the 2001 sequel. He was also featured in the 1999 film "Election."
