Many different parties can be sued following an accident with an 18-wheeler of semi-truck. It all depends on who is at fault. This could be the driver, the driver’s employer, the owner of the vehicle, the shipper, the trucking company, the company receiving the goods, or even a maintenance company that worked on the vehicle. Determining who is responsible after an accident is very complicated so hiring an experienced truck accident lawyer is very important to ensure you receive the greatest potential benefits.
