12:20 PM PT -- 6/23 -- Law enforcement sources tell TMZ ... Lil Yachty was issued a citation for driving too fast for conditions, failure to maintain lane and driving in the HOV lane.
We're told he was also issued a warning for not having his driver's license with him.
Lil Yachty got into a scary car wreck in Atlanta after his car and Mother Nature clashed ... which left his sweet ride totaled, but he's gonna be okay.
The rapper was driving on Georgia State Route 400 Monday during some nasty rain and spun out, smashing into a barrier along the shoulder. Our sources say there was a lot of standing water on the road, causing the sports car to hydroplane.
Yachty lost control and you can see how the impact destroyed his car.
Seems bad -- and it is -- but fortunately for him ... we're told Yachty was able to walk away relatively unscathed, with only minor injuries to his arm.
Emergency crews responded to the scene. It's unclear if Yachty went to a hospital for treatment. As for his whip ... there's no treating it, we're told it's totaled.
