It may seem like a silly question, but why do truck accidents happen? The cynical and obvious answer is that a truck collided with another vehicle, and the reason is't exactly important because accidents are just a part of life. But the reasons why these truck accidents happen is incredibly important, especially when it comes to determining liability and overall civil liability should a personal injury lawsuit be filed.
Truck accidents happen for a number of reasons. Sometimes it is the fault of other vehicles. Trucks are larger vehicles that take longer to slow down when traffic changes rapidly. So if you are merging in front of a truck suddenly or if you are driving in a truck's blind spot and then quickly approach them, they may not be able to react appropriately. Also, when a truck is trying to change lanes, you shouldn't speed up or try to somehow outmaneuver the truck. Allow them to merge safely into the lane.
At the same time, truck accidents can also be the fault of the truck driver or the truck company involved. There are so many potential circumstances here: the driver could be intoxicated, the driver could be distracted by his or her cell phone, or the driver may be operating the vehicle in an unsafe manner. This doesn't even cover the potential problems with loading the vehicle, and the way the cargo is left in the truck or flatbed. If it isn't properly loaded, then the truck could easily tip over or be difficult to safely operate.
There are many different legal angles to a truck accident, and it all depends on the circumstances of the particular case and what the investigation into each accident discovers.
