The Federal Motor Carrier Safety Administration sets hours of service rules for truckers that establish maximum amounts of time that they can be behind the wheel on any given day. These regulations are intended to combat the problem of truck driver fatigue, which causes drowsy driving and increases the chances of drivers making mistakes. An hours of service violation creates the possibility that you can sue the trucking company. The employer could then face liability for a driver's actions because the employer may have encouraged the driver to work longer than is allowed by law. The failure to comply with regulations makes proving negligence easier.
