Los Angeles, CA- Before former “Saturday Night Light” star Chris Kattan crashed his car and was arrested for DUI; he was acting bizarrely on a flight and needed assistance to depart the plane, sources say.

Kattan, 43, who starred opposite Will Ferrell in “A Night at the Roxbury,” was driving along the 101 Freeway in Encino when he crashed into a construction zone where road crews were making repairs. The collision occurred  just after 2 a.m. Sunday morning. Even though one lane was closed, and marked off with orange cones, Kattan ran crossed over into work zone and slammed into a construction zone buffer truck. No one was in the truck and, luckily, no one was injured, but Kattan’s Mercedes was nearly totaled.

Police received a call about a Mercedes weaving and driving slowly before Kattan’s crash.

In video taken at the scene, Kattan seems unsteady on his feet and could not successfully complete field sobriety tests. He can be seen stumbling through the heel to toe test and nearly fell. The arresting officer helped Kattan steady his feet before

Kattan apparently admitted to police that he had taken prescription drugs and was placed under arrest for misdemeanor DUI. He was released from police custody after posting $15,000 bail, but the comedian seemed to be in denial about the particulars of his arrest.

After being released from jail, Kattan told his fans on Twitter, “I passed all tests, released without bail, have drivers license, cop offered to drive me home.”

But before Kattan started to drive home, he was acting bizarrely on a international flight, according to TMZ. On his LA bound flight, the comic was pacing up and down the aisles of first class mumbling to himself about his medication.

Sources told TMZ Kattan was raving on about the three-hour flight delay and how he was going to run out of his prescription meds. Two doctors on the flight helped calm Kattan down, and when the flight landed he needed help getting off the plane. Just a few hours later he wrecked his luxury vehicle.

“I just got back from a 15hr flight after touring out of the country. I was exhausted. The Police were so kind,” he explained in a Monday tweet.

While in police custody, Kattan agreed to a blood test, but those results won’t be in for a few weeks. His first court date was scheduled for the first week of March.  His DUI is a misdemeanor so it’s highly unlikely he will spend any more time behind bars and will probably only have to pay a fine and attend alcohol and drug assessment courses if he manages to retain and savvy DUI attorney.

Even if Kattan, or any other driver, for that matter, has a prescription they won’t be excused for impaired driving.  Regardless of the substance, driving under the influence has severe consequences which can include loss of driving privileges, time behind bars and costly fines.
