Law enforcement sources tell TMZ, Shooter was driving a silver Audi (above) minding his own business ... when another driver made a poorly-timed turn and clipped the actor's bumper.
We're told the crash screwed up Shooter's axle ... so dude had to get his car towed -- but otherwise, it was a standard accident. According to law enforcement ... no arrests were made, no tickets were issued.
Citation or no citation -- you better stay out of his way, or you'll pay! Listen ... to what we say!
