If you drive through a flood, what should you do?

Engaging low gear and maintaining low engine revs while moving through a flood is a critical approach for several reasons. When driving in flood conditions, the vehicle's power is more effectively managed in low gear, which allows for better traction and control. Low engine revs help to prevent the engine from stalling, especially in deeper water where the risk of water ingestion into the engine becomes a concern.

Driving slowly through a flood also allows for better assessment of the road conditions and the depth of the water. This cautious approach reduces the likelihood of hydroplaning, where tires lose traction due to water, and it minimizes the risk of being swept away by strong currents.

In contrast, trying to speed through floodwaters increases the chances of losing control of the vehicle, as well as the potential for significant damage to the engine and other critical components. Stopping to wait for assistance, while sometimes necessary, may not be practical in all situations, especially if it places the driver at risk from rising waters. Engaging high gear is not advisable as it can cause the vehicle to move too quickly in unpredictable conditions, making control more difficult.
