- Description
An LH2 trailer-tractor was traveling on a highway. A second vehicle crossed the centreline striking the left rear tandems of the LH2 trailer. The impact caused the trailer-tractor to lose control and roll onto the road berm striking several small trees and a telephone pole. One of the trees ruptured the supply line to an inner tank pressure gauge releasing a small amount of hydrogen gas to atmosphere.
