Truck drivers are subject to the same rules of the road as all other travelers. This means that they must stop at red lights, obey speed limits, and take care to check blind spots before changing lanes. A trucker who violates these laws places all other people at a severe risk of injury. Furthermore, a conviction in traffic court for violating these laws can serve as potent evidence of fault in a civil claim for damages. In addition to the common traffic laws, additional federal regulations control the trucking industry.
