How to Drive Through Deep Road Water Accumulation?

First, downshift to reduce speed, keeping the engine RPM at 4000 per minute. This allows the engine's torque to counteract resistance, maintaining a smooth and steady speed. Control the throttle and avoid pressing it abruptly.

When encountering deep road water, I recommend first estimating the water depth—generally, it shouldn’t exceed half the height of the wheel hub. If it’s too deep, don’t force your way through; find a higher route or park and wait. If you must proceed, shift to a low gear, maintain steady throttle, and drive slowly at a constant speed. Avoid slamming on the brakes or accelerating suddenly to prevent pushing water waves into the engine. Manual transmission cars are easier to control in such situations. If the engine stalls, immediately turn it off and do not restart it—call a tow truck to take the car to a repair shop for inspection of the intake system and electrical circuits. During rainy days, make it a habit to check the windshield wipers and tire tread before driving. For unfamiliar roads, it’s safer to step out and scout the path or use a stick to measure the water depth. Safety always comes first—it’s far more important than rushing.
