He drove the wrong way down a one-way street and, when police stopped him, he had an open beer container in the front console, police said.
He also had his girlfriend, 42, and her 2-year-old son in the sport utility vehicle, police said.
Nassau County police said they arrested Dave McNab, 43, of Montego Bay, Jamaica, following the traffic stop at 4:55 a.m. Monday on Fourth Street in East Meadow. He was charged with aggravated driving while intoxicated under Leandra's Law, as well as with consuming alcohol in a motor vehicle and numerous vehicle and traffic law violations.
Police said officers saw McNab operating the 1998 Ford Explorer eastbound on Hempstead Turnpike in "an erratic manner." Police said McNab then turned right onto Third Street and then right onto Fourth -- a one-way street.
After "traveling a short distance in the wrong direction" on Fourth, police said they stopped McNab.
Leandra's Law is named for Leandra Rosado, an 11-year-old girl killed when the SUV she was riding in overturned on the Henry Hudson Parkway in 2009. The law makes it a felony to drive while intoxicated with anyone under age 16 in the vehicle, even on first offense.
McNab is scheduled for arraignment Monday in First District Court in Hempstead.
No one was injured.
