Drinking and driving is always a bad idea.

Drinking and driving in a sparkly silver Bentley convertible with a license plate that reads “SAUCED” is a terrible idea.

But that’s precisely what Denver Broncos running back Knowshon Moreno was doing when he got pulled over in south Denver. Moreno was charged with DUI and careless driving on Feb. 1 when he was stopped while allegedly driving 70 miles per hour in a 45 mph interstate construction zone.

And then there’s the license plate, which, according to a report from FOX31 in Denver , described Moreno’s state. The police officer who pulled Moreno over smelled alcohol on his breath and Moreno reportedly failed a roadside sobriety test. (Check out the car on FastandRare.com here.)

Denver District Attorney spokeswoman Lynn Kimbrough said Tuesday that the 24-year-old running back also faces a charge of failure to provide proof of insurance. He is due back in court on March 2.

”We take the incident involving Knowshon Moreno very seriously and are thoroughly reviewing this matter,” the Broncos said in a statement. “Our organization will continue to gather information and closely monitor this issue while the legal process runs its course.”

Moreno entered the season as Denver’s starting tailback but was ousted by resurgent veteran Willis McGahee. He underwent surgery to repair a torn ACL he suffered during a Nov. 13 game at Kansas City, and missed the rest of the season. Moreno is under contract for two more years with the Broncos, who drafted him No. 12 overall in 2009.
