# Bottom Loading Tanker Trucks

> Unlike top-loading tankers, where liquid is introduced through openings at the top of the tank, bottom-loading tanker trucks handle all transfer—loading and discharge—through ports on the undercarriage.

Unlike top-loading tankers, where liquid is introduced through openings at the top of the tank, bottom-loading tanker trucks handle all transfer—loading and discharge—through ports on the undercarriage. This keeps the system closed throughout, eliminating open-dome hazards such as vapour release, backflow, and overfill risk. In hazardous materials transport and food-grade liquid hauling, bottom-loading tankers are either legally required or represent the accepted industry standard in most major markets. For terminals and consignees, the practical benefits are faster turnaround, reduced cleaning requirements between product changes, and accurate volume tracking through integrated flow measurement.
