Many of us remember a central tenet of driver’s education school; if you rear end someone, it’s your fault. Why? Because it’s almost impossible for a driver to cause an accident in which he or she is struck from behind. It, therefore, stands to reason that the rear vehicle is to blame. This argument makes sense when two cars or light trucks are involved, but quickly falls apart when semi-trucks are involved. How? Semi-truck drivers operate under numerous regulations. When truck owners and drivers fail to follow these laws and regulations, they can be held responsible when another driver rear-ends them.
