Police said a Long Island man was not using a mandated anti-drunk driving device on his car when he struck a pedestrian in a parking lot on Wednesday night, seriously injuring her.

Interlock devices prevent a car from operating unless a sober person breathes into them, and the Suffolk County Police Department said 24-year-old Keylor Laporta did not have one in the 2011 Dodge Ram 1500 he was driving in the Huntington Station Target’s parking lot at the time of the incident.

Police did not specify why Laporta was mandated to use an interlock device or whether his blood alcohol level was tested at the site of Wednesday night’s crash, in which Laporta struck 68-year-old Teresa Kochan, a West Hills resident, in the lot off of East Jericho Turnpike.

Kochan sustained head injuries, police said, and was in serious condition at Huntington Hospital. Laporta, a Huntington Station resident, was not injured.

The man was charged with using a vehicle without an interlock device, a misdemeanor.

According to the New York State court system’s online database, Laporta also has two vehicle infractions against him in connection with the incident, operating an unregistered vehicle and failing to change an address on a license.

Attorney information for the defendant was not immediately available. He was scheduled to be arraigned on Thursday.

Police impounded the Dodge for a safety check.

Anyone with information is asked to call the SCPD’s 2nd Squad, whose detectives are investigating the case, at 631-854-8252.
