Police say a woman has been arrested under Leandra’s Law for driving while impaired by drugs with her infant daughter in the vehicle in Brentwood.

Police say Rachel Meyer, 28, was driving a 2009 Subaru Forrester westbound on the Long Island Expressway when she lost control of the vehicle and crashed it into the median near exit 53 at approximately 3 p.m. Sunday.

Officers responded to the scene and found Meyer unconscious in the front seat of the vehicle.

Officers determined that Meyer was under the influence of drugs.

Police say Meyer’s 4-month-old daughter was in a child restraint seat in the back seat of the vehicle.

Meyer and her daughter were transported to South Shore University Hospital in Bay Shore where they were evaluated and released. The two were then transported to the Fourth Precinct.

Meyer, of Huntington Station, was charged with aggravated driving while intoxicated with a child passenger 15 years old or younger and endangering the welfare of a child. The 4-month-old was released to a family member.

Meyer is scheduled to be arraigned in Central Islip today.
