A Rocky Point mother arrested in April on a Leandra's Law charge of driving while intoxicated with a 13-year-old in the car is scheduled to be arraigned Tuesday, Suffolk County District Attorney Thomas Spota said in a news release.

Colleen Lopez, 47, was driving with the girl in a Chevrolet Tahoe on Patchogue-Yaphank Road in Yaphank, when she was stopped by an officer with the Suffolk DWI enforcement unit, who said she failed to maintain her lane.

An investigation by the officer revealed that Lopez was under the influence of alcohol, police said.

Lopez was arrested and charged with aggravated driving while intoxicated with a passenger of 15 years old or younger, also known as Leandra's Law, along with endangering the welfare of a child.

Suffolk County Judge Stephen Braslow in Riverhead will unseal the indictment, the release said.

Leandra's Law is named for Leandra Rosado, 11, who was killed Oct. 11, 2009, in a DWI accident after the minivan in which she was a passenger crashed on the West Side Highway in Manhattan.
