A Staten Island man was charged with violating Leandra’s Law on Saturday afternoon after Suffolk County police said he drove while impaired by drugs with a young boy in the back seat before crashing his sedan in Huntington Station.

The crash happened around 2:50 p.m. at the corner of Jericho Turnpike and Longfellow Road. Police say they received a 911 call about someone driving erratically in the area. Minutes later, police said they found a 2015 Honda Accord had collided with a 1999 Dodge pickup truck.

The driver of the Honda, Mathew Moscowitch, 33, has been charged with felony aggravated unlicensed operation, possession of a hypodermic needle, aggravated driving while intoxicated with a child passenger 15 or younger, known as Leandra’s Law, and endangering the welfare of a child, police said.

Police said there was a 5-year-old boy in the back seat of Moscowitch’s car when the crash occurred.
