Benzino -- Busted for Drugs ... If Only He'd Buckled Up

If you cruise around on a suspended license in a slick Maserati like ex-"Love & Hip Hop: Atlanta" star Benzino allegedly just did ... make sure you wear your seat belt and don't have drugs on you.

Law enforcement sources tell TMZ ... Benzino was stopped by Atlanta cops late Wednesday afternoon simply for failing to buckle up, but then cops say they found a pot stash on him.

Benzino was hauled off to jail for the belt violation, suspended license and possession of marijuana. Bail was set at $2,269.00

This is Benzino's second arrest in the last few weeks -- he was pinched for trying to sneak a loaded 9MM through airport security in the ATL.
