Firefighter Lewis Moore Jr., 47, and an unidentified 16-year-old who was a passenger in the vehicle were hospitalized, but neither suffered life-threatening injuries.
Moore was at a training drill when he was sent to a brush fire in Far Hills.
The 1985 Chevrolet tanker's lights and siren were activated and as he approached an intersection, he ran a stop sign at the four-way stop before realizing he was going too fast.
The apparatus hit a bump in the road, sending its front end off the ground and causing it to fishtail before rolling over into opposite lane and ended up coming to a stop on the passenger's side.
Both Moore and the teen were transported to Morristown Memorial Hospital for treatment of multiple scrapes and lacerations to their arms and were treated and released.
The tanker truck was traveling 44 mph in a 35 mph zone before the crash, according to a police report.
Fire officials said the $400,000 tanker was totaled in the wreck and that it will take years to replace.
