What Are Jackknife Accidents and How Do They Happen?
When a semitruck is in a collision, sometimes it can cause a jackknife, which is when the cab and trailer fold in toward one another. The two parts of the up to 80,000-pound vehicle form a 90-degree angle, which is not only dangerous, but also looks unnatural and scary. In very bad accidents, the angle is even smaller, which can cause the cab and trailer to collapse into themselves.
Jackknife accidents are dangerous for semitruck drivers and regular vehicle drivers alike. Commercial truck drivers are in danger during a jackknife because the trailer hitting the cab can be deadly. Drivers of the surrounding regular vehicles are also in danger if they are in the path of the trailer, cab, or truck as a whole while folding. Even though the Federal Motor Carrier Safety Administration (FMCSA) reported that less than five percent of fatal accidents involve jackknifed tractor trailers, they are still serious scenarios to be aware of.
