Traditionally, commercial vehicle inspectors have placed a large emphasis on vehicle violations. Today, that focus is changing to the driver. Several recent studies have concluded that driver fatigue is one of the major contributors to commercial vehicle caused accidents. One of the most effective ways to combat this problem is to ensure drivers are following the hours of service rules. Federal regulations require each truck driver to keep a daily written record of duty status; commonly known as the driver’s logbook. A thorough inspection of the driver’s paperwork, load information, and logbook is just as important to the safe operation of the vehicle as verifying the brakes are properly adjusted. In order to make sure that drivers are complying with the hours of service rules, inspectors must focus their attention to the driver’s logbook. The Hidden Truth will show the viewer several practical techniques to discover the presence of false log books.
