Few trucking safety experts have spent any time personally supervising the daily operations of truck drivers. Andy Sievers is unique in this regard. For the first three years of Andy Sievers’ trucking career, he was responsible for the day-to-day operations of a large fleet of truck drivers and their assigned tractor-trailers. Mr. Sievers dispatched the drivers and verified their daily hours of service. Additionally, Mr. Sievers managed the compliance, safety and maintenance of the fleets of drivers and vehicles that operated under his supervision. This daily responsibility is critical to the credibility of a safety expert in commenting on the appropriateness of the supervision of individual truck drivers.
