When crossing flood water, which approach is recommended?

• A. High gear with high engine speed
• B. Low gear with high engine speed
• C. High gear with low engine speed
• D. Normal gear with normal engine speed

Answer: (B)

When crossing flood water, you need enough engine torque to push through the resistance while avoiding stalling. Using a low gear places the engine in a range where it can deliver strong torque even at low wheel speeds, which is crucial as the water slows you down. Keeping engine speed high ensures the engine stays in its usable power band and won’t stall as you push through, and it helps maintain a steady flow of air and fuel to keep the engine running smoothly. A higher gear or not revving the engine enough would reduce torque and increase the risk of stalling or getting stuck, while using a normal gear with normal revs wouldn’t provide the necessary low-speed torque through the water.
