Proving that the truck driver breached their duty of care to the plaintiff is often the central issue of a truck accident lawsuit. Any violation of Missouri traffic laws could result in a breach of the duty of care if it resulted in a collision. However, there are additional duties owed by a commercial operator that the driver of a personal vehicle does not have to comply with. These include federal regulations regarding the hours a truck driver can stay on the road without a break, as well as regulations regarding the manner the operator packs the trailer.
