The first incident was a vehicle fire. As firefighters were doing traffic control for that around 2:30 a.m., a tractor-trailer, which failed to see the emergency vehicles with their lights activated, tried to make a sudden lane change and crashed, according to state police.  

The tractor-trailer hit two fire vehicles, a fire truck and a Chevrolet Equinox, before going off the road and into a ditch. Six firefighters, five from West Hanover Fire and 1 from East Hanover Fire, were taken to Hershey Medical Center with what were described as non-life threatening injuries.

Four firefighters were taken to a hospital to be checked out.DeGeorge said their injuries did not appear serious.

According to Fire Chief Roberto Rojas, the department has not had a new customized truck in about 30 years. It comes equipped with all the latest technology including a larger tank to fight the toughest of fires.
