*Lil Wayne has checked in with the probation department in Yuma County, Arizona to begin his three year sentence stemming from the tour bus incident of 2008.

The rapper has been ordered to three years of unsupervised probation and 360 hours of community service — which he will perform in Miami, where he resides, TMZ reports.

Wayne was arrested after his tour bus was stopped at a U.S. Border Patrol checkpoint near Yuma — and authorities claim they found cocaine, ecstasy and a handgun on board.

Weezy pled guilty to one count of felony possession of a dangerous drug — while the other drug charges and the gun charge were all thrown out.

If the artist stays out of trouble, Yuma officials will drop the felony to a misdemeanor.  He’s due to report to the probation office in Miami by Nov. 10.
