Tractor trailer jack-knifes on Highway 210
A tractor trailer jack-knifed on the ramp from Interstate 435 to Highway 210, shutting down traffic in that area for some time.
According to the Missouri State Highway Patrol, the driver lost control and began to jack-knife around 3:30 a.m. The rig skidded down the ramp, struck a freeway sign and came to a rest blocking the ramp.
Fortunately, nobody was injured in this Missouri tractor trailer accident.
Jack-knife crashes can cause serious damage. A jack-knife occurs when the angle between the cab and the trailer of a large truck becomes too severe and the trailer begins pushing the cab out of control. Once a tractor trailer has entered a jack-knife position, it is impossible for the driver to regain control and the whole rig can enter a slide. Since commercial trucks can weigh up to 80,000 pounds, they can slide for hundreds of feet and, in the worst tractor trailer crash scenario, crush smaller passenger cars along the way.
