Three volunteer firefighters were hospitalized after police say they were struck by a vehicle while responding to a crash scene in Uxbridge.

First-responders were called to the area of Wagg Road and Highway 47 on Sunday night for a reported collision.

The area was closed to traffic for several hours for the police investigation.
