Three people were injured in the three-car accident - one of them ejected from his car - but none of the injuries turned out to be serious. Rockville Centre police and fire personnel who responded to a call at 10:42 a.m. on Jan. 16 were joined by detectives from the Nassau County Police Department Homicide Squad to investigate the incident, which began when the gas pedal of a 2003 Cadillac heading west on Sunrise Highway got stuck and the vehicle's brakes apparently failed. In an attempt to stop his car, the 50-year-old driver pulled into the left-turn lane and tried to use the median to bring the vehicle to a halt. He struck the rear of a 1996 Nissan that was turning south from Sunrise Highway onto Oceanside Road, and its 23-year-old driver, who was not wearing a seat belt, was ejected through the driver's-side window into a parking lot to the west of Oceanside Road. The Cadillac continued west on Sunrise Highway and struck a westbound 2000 Ford, operated by a woman of about 60. The Cadillac finally stopped about 500 feet east of Forest Avenue. Its driver was taken by ambulance to South Nassau Communities Hospital, where he was treated for minor lacerations to the head. The man who was ejected was transported by ambulance to Nassau University Medical Center, where he was evaluated and found to have sustained only a broken leg. The woman driving the Ford complained of various pains, but refused medical attention at the scene. Comments about this story? RVCeditor@liherald.com or (516) 569-4000 ext. 208.
