What Are Jackknife and Underride Truck Crashes?<\/h2>\n

A jackknife crash is when a truck’s trailer swings out sideways. An underride crash is when a smaller vehicle slides under a truck’s trailer.<\/p>\n

In a jackknife<\/strong>, the trailer folds toward the cab at a sharp angle. Think of a pocketknife closing. It usually happens after hard braking, lost traction, or too much speed. The trailer can sweep across several lanes and crush everything in its path.<\/p>\n

In an underride<\/strong>, a car slides under the side or back of a trailer. A big rig sits high off the road. So the car’s front bumper and hood pass beneath the trailer. This is called underride. Sometimes a truck rides up over a smaller car instead. That is called an “override” crash. People search for both terms, and we handle both.<\/p>\n

We group these crashes together for one reason. They cause some of the worst injuries on the road.<\/p>\n

Why an Underride Truck Accident Injury Lawyer Handles Catastrophic Injuries<\/h2>\n

These crashes are so dangerous because the trailer can skip past a car’s safety features. It can then strike the passenger area directly.<\/p>\n

Your car has crumple zones, airbags, and door beams. They are built to soak up force in a normal crash. But in an underride, the trailer often hits at windshield height. That skips past those protections. It reaches right into the space where people sit.<\/p>\n

The result is often a catastrophic, permanent injury:<\/p>\n
