SAVANNAH, N.Y. — Authorities say a school bus full of elementary school students collided with a snowplow on a central New York road, injuring 17 children and the bus driver.

Wayne County sheriff’s officials say two of the injured students were trapped in the bus for about 30 minutes and the woman driver was trapped for about an hour.

A spokeswoman at Upstate University Hospital in Syracuse says an 11-year-old boy and the driver are being treated after being flown there by helicopter.

The Clyde-Savannah Central School District bus carrying 22 children hit the plow around 7:50 a.m. today at an intersection in the rural town of Savannah, 30 miles west of Syracuse.

Sixteen children were taken to a nearby hospital, where nine of them were treated and released and one was transferred to a Rochester hospital. The plow driver wasn’t hurt.
