Soulja Boy Car Accident -- Yeah, I Was Driving ... But SHE'S A RACIST!!!

Soulja Boy is finally admitting he was behind the wheel when his red Bentley got into a car accident Saturday night in Hollywood -- but the rapper insists ... the other driver isn't just at fault ... she's also a giant RACIST.

Soulja just released a video statement on YouTube, claiming the other driver "ran the light. Our light was green. We were going straight. She turned too fast, thought she was gonna make it, hit my car."

He adds, "You know what that was. That was some people trying to come up on some money ... I was going straight in line." Soulja also says the other driver was "racist" and accused him of driving a stolen vehicle.

People close to Soulja previously said the rapper wasn't driving -- his bodyguard was.

As for the Bentley, Soulja said it took the bigger beating in the accident -- and now, it's in the shop getting fixed. Soulja says it'll take about a week to repair.
