Two firefighters have been sent to hospital after a tractor-trailer collided into a fire truck. The fire truck was on the scene of an earlier collision blocking a live lane - WB #Hwy401/Newtonville Rd. 2:30am. The fire fighters were inside their vehicle at the time of the collision. The injuries are considered non-life threatening. I expect two more hours before a full reopening of the highway.(est 10am) opp_hsd #SlowDownMoveOver ^ks
