NEW YORK — A teenage driver without a license crashed into a school bus on a suburban Westchester County freeway, injuring at least nine people in the head-on collision, police say.

The crash happened shortly after 2 p.m. Wednesday on Lake Road in the town of New Castlesaid the police. The driver of a Honda Accord, a 16-year-old from Bedford Hills who did not have a driver’s license, was traveling south with three passengers in the car when he lost control of the vehicle on a bend.

The car veered into oncoming traffic lanes and crashed head-on into the school bus, police said. The four people inside the Accord were taken to Westchester Medical Center with life-threatening injuries, New Castle Police said.

It was not clear how many people were on the Yorktown Central School District school bus, or what their ages were. Everyone on board was also taken to hospital, but all are expected to recover.

It is not known how and why the driver lost control of the sedan he was driving. Police did not say whether the driver had a learner’s permit, which would allow him to be on local roads as long as he has a passenger who is at least 21 years old. It was also not known how old the passengers in the car were.

The car was then separated from the bus and towed away from the scene. The road where the accident occurred was closed for hours, but reopened on Wednesday evening.
