Justin Bieber took his Can-Am Spyder into Bev Hills Thursday ... and when traffic got too congested for his taste, he maneuvered it onto the sidewalk where he rode illegally ... almost hitting someone.
Watch the video closely ... you'll see Bieber comes off the sidewalk at an intersection, and comes close to creaming an elderly woman with a walker.
He clearly doesn't care ... because seconds later he's rocking out to music as he waits at a light.
BTW ... Bieber's on probation for the egg throwing incident, which means he's not allowed to violate any laws. Lucky for him ... no cops in sight.
