Just weeks after leaving rehab, NBA star Ty Lawson has returned to the Hollywood club scene ... only smarter ... this time, leaving as a PASSENGER in a waiting ride, TMZ Sports has learned.
The Houston Rockets star -- who was arrested for DUI back in July and in January -- was leaving Warwick on Sunset Blvd. around 1:40 AM ... but appeared completely sober.
It's not illegal for Lawson to be around booze -- he's just not allowed to drink it -- which is why the judge in his Denver DUI case ordered him to be on monitored sobriety and install a monitoring device in his home.
So, while it might not be the BEST move to hit the clubs while in the middle of TWO DUI cases -- at least he was responsible about it.
