Miss USA Rima Fakih -- Strikes Plea Deal in DUI Case

Disgraced former Miss USA Rima Fakih struck a deal with Michigan prosecutors in her DUI case this morning ... just hours before she was due to stand trial for the December incident.

Fakih pled no contest to misdemeanor driving while visibly impaired ... stemming from her arrest in Detroit on December 3. In exchange, prosecutors have agreed to drop the more serious charge of operating while intoxicated.

After court, Fakih said, "You learn, you pay your price for making mistakes and you move on. I'm very happy I can put this behind me."

Sentencing is scheduled for May 9 -- Fakih faces up to 93 days behind bars.

As we previously reported, cops say Fakih was disoriented and was slurring her speech after she was pulled over for speeding and weaving through traffic in Dec.

Cops also say Fakih's blood alcohol level was more than DOUBLE the legal limit ... and claim she had a half-empty bottle of wine on the floorboard behind the driver's seat.
