It is easy to assume that a trucker is always at fault when a semitruck slams into another vehicle. This isn't always the case. There are causes of big-rig accidents that don't have anything to do with the trucker. Still, most people don't want to consider these. Instead, they want to think of the trucker as evil personified.
In some cases, the semitruck crash might be an equipment failure. In these cases, determining who didn't do what they were supposed to do is important. If the reason for the failure was a defective component, you might be looking at a product liability claim instead of a semitruck wreck lawsuit.
One of the possible causes of an 18-wheeler crash is that another vehicle cut the semitruck off. These large vehicles can't stop suddenly. If a driver darts in front of the truck, there is a chance that the trucker won't be able to stop in time. This could lead them to rear-end a vehicle. If the trucker has a reaction to avoid the vehicle in front of them, they might end up sideswiping another car. It is imperative that all drivers stay out of the trucker's blind spots and that they give these large trucks clearance to maneuver.
Another issue that can lead to crashes is an unsecured or improperly secured load. As the trucker drives, the load might shift. It can come off the truck, but it might remain in place while the truck begins to skid. If it remains in place, it might cause the truck to become unbalanced and skid.
If you are injured in a semitruck wreck, make sure you get medical care and that you understand your options. This enables you to make an informed decision about what's going on.
