One of the issues in any case is what are the standards the truck driver and trucking company required to meet? There are industry standards, which are frequently higher than that required of the government, but at a minimum all drivers and trucking companies must meet the government standards for safe operation. These standards are what are inspected by the FMCSA’s field investigators.
In order that inspections are uniform, and everyone in the industry knows what to expect from the field investigators, the FMCSA puts forth Field Operators Training Manual. Any serious trucking lawyer should have a copy on file in his or her office. For example Chapter 1.4.7 deals with driving of commercial motor vehicles and 126.96.36.199 deals with Hours of Service violations, topics I have blogged on extensively in the past.
