Trucks or commercial vehicles have a big presence on the roadway that can not only be intimidating, it can be dangerous in the wrong situation. They can weigh between 10,000 and 80,000 pounds. Passenger cars a significantly lighter and shorter, making them no match for their big truck cousins. But the reality is, as big as those trucks are, they are not always the cause of truck car accidents. In fact, cars are liable for 75% of all such accidents. Passenger vehicles can impede the movement of a truck for many seemingly minor infractions that can have serious consequences for a big rig. Yet when truck drivers do cause these collisions, they are often for unlikely reasons like simple driver fatigue. Determining liability in truck car accidents is a complex process that requires the expertise of a truck accident attorney who can assess the evidence accurately.
