Chris Klein has been charged on two misdemeanour counts of driving under the influence (DUI).
The 'American Pie' star - who was arrested after failing a sobriety test in the early hours of the morning on June 16 while driving in Los Angeles - has reportedly been charged on a count for DUI with a prior and one count of driving with a .08 blood alcohol level or higher.
After being pulled over, the 31-year-old star was made to undergo two breathalyser tests which showed he was three times over the legal driving alcohol limit in Los Angeles, according to gossip website TMZ.
If convicted of the charges Klein could face up to a year in jail and be ordered to pay a $1,000 fine with the possibility of other financial penalties.
A police report claims he was "observed weaving from number three lane into the second and number four lane westbound US 1010 at Woodman Ave".
It is not the first time the 31-year-old actor - who is currently undergoing a 30-day alcohol addiction program at the Cirque Lodge rehab centre in Utah - has been charged with DUI.
In 2005, he was arrested and later charged with two misdemeanour counts of DUI in San Diego - exceeding the blood-alcohol limit in California by more than double.
He had to undergo community service and saw his driving license suspended for 90 days, and received a $1,800 fine.
