It's worse with a tractor trailer, and really bad with a top heavy bulk tanker, or an unbaffled liquid tank with a slosh load. During my corporate tour I taught a defensive driving class during new hire orientation. All new employees attended, whether drivers or not. The key to avoiding a roll over with a tanker is to avoid jerking the steering wheel or hard braking, while applying just enough throttle to stabilize the trailer, like maintaining minimal speed on a bike to keep from tipping over.
One of my students was our gorgeous new receptionist at the corporate front desk. She was hired for her looks, not her brains. A few weeks after attending my class, she did a barrel roll with her new Camaro, while trying to avoid a pile up on the Dan Ryan Expressway in rush hour Chicago traffic. Her car was demolished, but she was wearing her seat belt, and got out with a few scratches. When she returned to work, she asked whether I said gas or brake in that situation. When I told her the answer, she said she figured she got it wrong, when she jammed the brakes on while swerving. Fortunately, she was on the same page on the seat belt question.
