Two children and four adults were injured in a crash in Old Westbury on Tuesday, according to the Old Westbury police chief.

Old Westbury Police Chief Stuart Cameron says it happened just before 3:30 p.m. when a dump truck, loaded with asphalt, was approaching a red light and went through the intersection on Post Road and Store Hill Road, hitting a school bus and SUV.

The 66-year-old driver of the truck told police that the truck's brakes were not working as he approached the intersection.

"The truck collided with both the SUV and the school bus and overturned." Cameron said.

Police say the load of asphalt spilled into the road when the dump truck overturned.

Cameron says the children, a 10-year-old boy and girl from the Westbury School District, the bus driver and an aide went to the hospital, as well as the driver of the SUV and the dump truck driver.

The police chief says everyone's injuries are not serious.

The intersection was shut down for about five hours as crews worked to separate the vehicles and clear the asphalt.

First responders from Old Westbury, the Nassau County Police Department and NYS Department of Environmental Conservation responded to the crash.

According to the DEC, 30 gallons of diesel fuel spilled, however there's no environmental impact.

A representative with the Westbury School District tells News 12 that the 10-year-old's parents took them to the hospital themselves.

Cameron says the dump truck is being inspected and police are working to find out if the brakes failed.

"This accident could have been a lot worse," Cameron said.
