Eight people were injured when a bus crashed into a semi-truck on the New York State Thruway early Tuesday morning, police said.

The accident occurred in Sloatsburg, about 30 miles northwest of New York City, causing backups for many morning rush-hour commuters.

Among the injured was the Trailways bus driver, who rear ended a tractor-trailer operated by a Quebec, Canada, truck driver, who had slowed down for a car entering the highway from a rest area. The bus driver and seven passengers were transported to local hospitals for treatment of their injuries.

The bus was en route from Kingston, New York, to New York City.
