United States highways are the backbone of interstate freight transportation. In 2018, there were approximately 37 million commercial trucks registered in the U.S. In 2019, trucking companies grossed nearly $800 billion, making up more than 80% of the nation’s total freight revenue. With so many trucks on the roadways, collisions are inevitable. Tractor-trailers can weigh over 100,000 pounds–35 times more than the weight of the average passenger car. The size and weight of these trucks make them exceptionally dangerous when an accident occurs, and victims are more likely to suffer catastrophic injuries or even lose their life.
