Tiffany Haddish is facing a DUI charge after cops say she was dozing in the driver's seat of her vehicle early Friday morning in Georgia ... TMZ has learned.
Law enforcement tells us Tiffany was arrested by Peachtree City PD officers around 4 AM ET. Although she was getting booked for DUI, the comedian still managed to smile for the camera when cops snapped her mug shot.
Cops were responding to a call for a driver who'd fallen asleep at the wheel. Officers had a description of the vehicle and were on the lookout for it when they spotted Tiffany pulling into a neighborhood.
They stopped her and arrested her for DUI and improper stopping on a roadway. Cops believe she'd smoked marijuana.
Tiffany was only in police custody for a few hours. According to records, obtained by TMZ, she posted $1,666 to bond out of jail around 6:30 AM.
We've reached out to Tiffany's reps for comment, but no word back yet.
Obviously, it's no excuse for driving impaired ... but we do know Tiffany's been dealing with a lot of loss lately. Sources connected tell us her grandmother, who raised her, recently died -- as did her dog, and her close friends Bob Saget and producer Carl Craig.
