Stephen Colbert jumped on board the "Carpocalypse" bandwagon Thursday on 'The Colbert Report' (Weeknights, 11:30PM ET on Comedy Central), joining forces with those freaking out about the closure of California's I-405 through the weekend on. Sure, the 405 is the busiest highway in the country, but it's still just a road closure.

But that hasn't stopped Californians, and the media, from using apocalyptic terms to describe the situation like "carmageddon" and "carpocalypse."

"This is the big one, folks," he said, emphasizing that this is far worse than the earthquakes, wildfires and other hardships Californians have endured. "Increased traffic on two off-peak days. Do you know what that means? Someone might have to walk someplace!"

In a case of "I'm not a cop but I play one on TV ... " veteran 'CHiPs' star Erik Estrada has teamed up with "real motorcycle police officers" for a PSA warning Los Angelenos about the oncoming cataclysm known as "Carmageddon."

L.A. drivers are preparing for a 53-hour shutdown of a 10-mile stretch of the I-405 from July 15th to 18th, which could paralyze the whole area.

In true Hollywood style, L.A. Metro asked Estrada -- a.k.a. Officer Frank "Ponch" Poncharello -- to record the PSA (in English and Spanish) reminding drivers to stay away from the area during the closure.
