Gabriela Baena was arrested for felony drunk driving ... TMZ has learned.

The "Dangerous Woman" singer was driving in L.A. last night at around 2 AM when she made an illegal turn and ran her 2016 Tesla Model S into a BMW. Our law enforcement sources say the driver claimed injury.

Cops came, gave the 22-year-old singer a field sobriety test and promptly arrested her for felony DUI. It's standard operating procedure for cops to arrest for a felony when there's injury.

Gabriela got a break as authorities decided to bump it down to a misdemeanor because the injury was minor and she blew a .12, not that much over the .08 legal limit. 

Gabriela -- who's out on $100k bail -- has been charged with 2 criminal offenses ... driving under the influence and driving with a .08 blood alcohol level or higher. 

We reached out to her reps ... so far no word back.
