An off-duty transit worker was busted for drunk driving in Brooklyn early today, authorities said

Cops spotted MTA employee Rosario Luis, 49, sleeping in a black 2010 Acura in Bedford Stuyvesant shortly before 1:30 a.m. today.

Half of his car was on the sidewalk at the corner of Nostrand Avenue and Vernon Avenue, police sources said.

The vehicle was still running, and sources said there was a strong alcohol odor on Luis.

He was taken into police custody, and a Breathalyzer test found his blood alcohol content was more than twice the legal limit of 0.08 percent, sources said.
