Should You Use First or Second Gear When Driving Through Water?

When driving through water, it is essential to pass through in one go without stopping or stalling the engine. Use first or second gear to maintain a steady speed, keeping the engine speed above 1000 RPM to ensure it runs at a high speed. You can appropriately control the speed using the clutch and brakes, proceeding with caution. Here are some precautions for driving through water: 1. Avoid manhole covers: Follow the path taken by vehicles ahead that have safely passed through the water. Do not take alternative routes. If driving alone, avoid the middle of the road, as manhole covers are often located there, and missing covers can lead to accidents. On familiar roads, rely on your usual impressions to navigate and avoid manhole covers. 2. Do not follow another vehicle too closely when driving through water: If the vehicle ahead breaks down and stops in the water, the risk increases. Also, avoid multiple vehicles driving through water simultaneously, as this can create waves that disrupt each other's sense of direction.
I was driving through a heavy rainstorm and chose to use first gear when passing through a flooded area because it helps maintain a steady speed and prevents water from entering the engine and stalling it. If you accelerate too quickly in a higher gear, the splashes kicked up by the tires are more likely to enter the exhaust system, causing the vehicle to break down or suffer internal damage. When driving through water, always enter and exit slowly, keeping a steady pressure on the throttle without letting go—releasing the throttle suddenly can allow water pressure to rush directly into the engine. If the water depth exceeds half the height of the wheel hubs, don’t take the risk—find an alternative route instead. Regularly maintain waterproof components and inspect the exhaust and intake systems to prepare for unexpected situations. Remember, safety comes first—better to stop than to take unnecessary risks.
