Dennis Quaid NOT Cited for DUI After Traffic Stop

0617_dennis_quaid_tmz_duiDennis Quaid pulled off something most people in Hollywood can't these days -- he was NOT busted for DUI yesterday after getting a field sobriety test ... TMZ has learned.

Law enforcement sources tell TMZ ... Quaid was pulled over in Marina del Rey for a stop sign violation when the officers decided to conduct a DUI investigation.

We're told cops determined DQ was not under the influence of anything and sent him on his way ... without so much as a ticket for the stop sign thing.

Seems like a small price to pay to get out of a moving violation.
