Abstract: A hose tray for storing a fluid fill and drain hose for a liquid transport truck includes a cover having a closed position covering the tray to prevent access to, or accidental loss of, the hose and an open position permitting access to the hose. The tray is mounted on the vehicle adjacent, and extending longitudinally of, the liquid transport tank. The tray includes a safety interlock such that when the cover is in the open position, the truck brake system is actuated to prevent movement of the truck. This prevents movement of the truck such as would tear the hose from the truck drain fitting, causing spilling of the tank contents. This is extremely important, particularly in view of the flammable nature of many liquids transported in tank trucks, and further in view of the expense to repair torn and damaged drain hose and fittings for such trucks.
