At 20 mph, MWS Apparatus must stop within:

• A. 25 Feet
• B. 35 Feet
• C. 45 Feet
• D. 55 Feet

Answer: (B)

Stopping distance is the distance a vehicle needs to come to a complete stop from a given speed, and training for the Mobile Water Supply apparatus uses a standard distance at 20 mph. At this speed, 35 feet is the established distance the vehicle must be able to stop within. This figure reflects the heavy mass of a loaded MWS, the braking system’s capabilities, and typical surface conditions, providing a safe margin for stopping under normal operating conditions. Shorter distances wouldn’t reliably accommodate the vehicle’s weight and braking performance, while longer distances exceed the standard requirement. Keep in mind that wet or icy pavement or worn brakes would require more distance, so drivers adjust speed and following distance accordingly.
