Tractor-trailer driver Maxwell Taylor, 56, of Amsterdam, New York, has now been charged.
Detectives say a tractor-trailer delivery truck for Walmart was traveling southbound on Newbridge Road near Falcon Street in East Meadow, when its sideview mirror struck a school bus occupied by 18 student passengers.
Police say Taylor did not stop and continued southbound, colliding with seven occupied vehicles near Stop & Shop on Jerusalem Avenue in North Bellmore, before overturning into the Stop & Shop parking lot.
Four adults and two children suffered minor injuries and were transported to the hospital for treatment and evaluation. Taylor was among the four adults.
A 16-year-old student passenger on the school bus also suffered minor injuries and was treated at the scene.
The accident shut down the busy intersection for hours.
Taylor is facing two counts of leaving the scene of an incident and was released.
He is due back at First District Court in Hempstead on June 14.
