Vivica A. Fox pleaded not guilty to two misdemeanor counts of DUI in a Van Nuys, Calif. courthouse on Thursday.
The actress did not appear in court. The plea was entered by her attorney, Richard Hutton, who previously represented Paris Hilton.
On March 20, Fox was arrested on suspicion of driving under the influence, according to the California Highway Patrol.
Around 11 p.m., a patrol car noticed Fox's silver Cadillac SRX traveling on a Los Angeles freeway at about 80 mph in a 65-mph zone, and she was unable to drive within her lane, CHP spokesman Leland Tang said.
"Fox exhibited signs of alcohol intoxication," said Tang. "A field sobriety test was administered and she scored over 0.08," which is the legal limit in California.
If convicted on both charges, Fox faces a maximum of six months in jail and a $1,000 fine.
Fox, 43, appeared on Dancing with the Stars
and the films Kill Bill: Vol. 1
and Soul Food.
A trial date was set for Oct. 29.
