In some cases, an accident victim may be able to sue parties other than the at-fault driver. For example, if the at-fault driver did not own the car, the car's owner may also be liable for your damages. If the at-fault driver was impaired from consuming too much alcohol, you may be able to bring a "dram shop" complaint against a business that served alcohol to the driver even though he was visibly impaired. In some cases, you may be able to bring an action against another party, such as an automobile manufacturer or construction company, if a defect in the vehicle or the roadway caused the accident. If the accident involved a tractor-trailer, the driver's violation of rules and regulations may be the basis for a lawsuit against the driver or his or her employer.
