Andrew Bynum -- Cops Crack Down on Bad Pass

L.A. Lakers star Andrew Bynum FOR THREE ... run-ins with police in the month in December!!!

Law enforcement sources tell us ... Bynum was pulled over by Culver City PD in early December for allegedly trying to pass another vehicle ... by crossing a divider and driving on the wrong side of the road.

We're told Bynum was cited for illegal passing and sent on his way ... and was extremely cooperative with the officers.

Here's the rub -- the incident went down JUST DAYS BEFORE Bynum earned himself two more driving tickets on separate occasions -- one for tinted tail lights and a missing license plate, and one for speeding.

It hasn't been a great month for the NBA player -- dude had to serve a 4 game suspension for elbowing JJ Barrea during the playoffs last year (below).
