Large commercial vehicles such as semi-trucks pose a unique danger on the roadway. Their large blind spots, extended stopping distance, and high center of gravity are often a factor in collisions with other vehicles.

In lawsuits involving truck accidents, an important piece of evidence often presented is the trucking company's work log. Many truck drivers violate hours-of-service regulations in an effort to meet delivery deadlines. These drivers may become fatigued and lose their ability to operate a vehicle safely. A company work log can reveal this type of work violation and help prove a truck driver's liability.

When investigating the cause of a truck accident, time is of the essence since trucking companies are required to retain their work records for only a matter of months. If they are lost or destroyed, it can be difficult to prove negligence on the part of the truck driver.
