What is the lowest acceptable fuel gauge reading?

• A. 1/2 Tank
• B. Full
• C. 1/4 Tank
• D. 3/4 Tank

Answer: (D)

Fuel planning and keeping a safety margin are the focus. In a Mobile Water Supply fire practice drill, you need enough fuel to run the vehicle and power any pumps for the full scope of the exercise and still have a reserve to get back safely. A reading of three-quarters of a tank provides that practical cushion—you’re unlikely to run out during the drill, even if there are small delays, detours, or extra pump operation. Dropping to half a tank or a quarter leaves insufficient time to complete the exercise and return without refueling, which isn’t acceptable for safety and reliability. Having a full tank isn’t necessary for this minimum standard, since three-quarters already ensures adequate range and reserve.
