How can I roll over my tractor trailer?

I agree it "shouldn't " take being a hazmat tank driver to be professional...BUT, "GasHauler", as you know we have a vested interest in being professional. If we are professional and safe (and really, what choice do we have ?) we live. If not, we die. I've seen a few good friends over the years that have made the proverbial big mistake...and all paid with their lives. All were good people, good drivers with the best intentions. It only takes once.
