VAN NUYS ( — “Saturday Night Live” star Chris Kattan was sentenced to three years of probation Thursday for driving under the influence of drugs and rear-ending a Caltrans vehicle.

Kattan, 43, after making an open plea to the court on the misdemeanor charge, was also ordered to attend a three-month alcohol-education program, 104 Narcotics Anonymous meetings and ordered not to drive with any measurable drugs in his system without a prescription, according to Frank Mateljian of the City Attorney’s Office.

Los Angeles Superior Court Commissioner Dennis Mulcahy also ordered Kattan to pay a $500 penalty, plus fees.

The actor and comedian was arrested about 2 a.m. on Feb. 10 while driving on the westbound Ventura (101) Freeway west of Balboa Boulevard.

According to the California Highway Patrol, a Caltrans crew had the right lane of the freeway blocked off for guardrail maintenance, when the driver of a 2011 Mercedes Benz approached, weaving across the roadway at slow speeds.

The driver, later identified as Kattan, drove through the cones on the freeway and struck the rear of a Caltrans vehicle. No Caltrans workers were injured.

A restitution hearing scheduled for Sept. 16 will determine how much Kattan may owe the state for damage caused the Caltrans vehicle, Mateljian said.

Shortly after his arrest, Kattan tweeted, “I just got back from a 15hr flight after touring out of the country. I was exhausted. The police were so kind. I’m lucky nobody was hurt.”
