Driving through floodwater

In view of the recent difficulties especially on the local back roads, here is some helpful guidance for you:

Using first or second gear (L or 1 in an automatic) drive slowly to avoid creating a large 'bow wave' (a small wave can be helpful but too much and the water can wash back into the engine). Slipping the clutch and revving the engine will also help to keep the exhaust clear and keep the engine running if water splashes onto the electrics. In an automatic keep your foot on the gas in the lowest held gear and use the brake to control your speed (and hope for the best!).

In some cases a stalled engine can result in water being sucked back through the exhaust into the cylinders - this can cause extensive and expensive damage. Do not change gear because this can also cause water to be sucked back through the exhaust (due to the change in engine speed and manifold depression).
