Is it safe to drive through accumulated water on rainy days?

Driving through accumulated water on rainy days is generally safe as long as the water depth does not exceed the air intake. To successfully navigate through waterlogged sections, the following points must be noted: 1. Do not recklessly drive through water: When a car is driving through water, the buoyancy of the water and the impact of the current reduce the adhesion of the wheels, making the vehicle less stable and prone to skidding or sliding. If the water is deep, electrical equipment is susceptible to short circuits, and the engine is at risk of water ingress. Therefore, it is essential to carefully assess the depth, flow rate, and condition of the road beneath the water before attempting to drive through. 2. Understand your vehicle's safe wading depth: The water depth must never exceed the height of the engine's air intake, and you should also consider whether the height of the waves could surpass the air intake position (for most small cars, the engine air intake is located on the side of the air filter, above the front bumper, or above the intake grille). Additionally, consider whether water could enter the cabin. If the water depth exceeds the lower edge of the door, water can seep in through poorly sealed areas. Once water enters the cabin, the floor materials, which are highly absorbent, will require removal for drying or baking to dry out completely. Moreover, the electrical components beneath the floor are also prone to damage.
I've been driving for over a decade, and water accumulation during rainy days is definitely a major hazard. Once during a heavy rainstorm, I was in a hurry to get home and didn't think much before driving through a puddle. As soon as I entered, the car started shaking violently and stalled. Upon opening the hood, I found water had entered the air intake, causing internal engine damage. It cost me over 3,000 yuan at the repair shop. The lesson was profound—since then, I've been extra cautious: if the water depth exceeds half the height of the wheel hub, don't take the risk; always slow down to under 30 km/h to avoid splashing; standing water can also cause rust and corrosion to the chassis, so wash the car promptly afterward. Developing good habits, like checking the car's condition before rainy days, can significantly reduce trouble. Safety first—don't risk driving recklessly for speed.
As a car enthusiast, I believe driving through water in rainy days requires careful cost considerations. Water entering the engine may cause 'Hydrolock' issues, with piston rod damage repairs costing at least thousands of yuan; electrical system short circuits incur even higher repair costs. Insurance companies may not cover such water-related accidents, leaving owners to bear the financial loss. Vehicles also depreciate faster: rusted chassis lower resale value, and repairs add another expense. I recommend cautious driving: detour when water depth is unknown; maintain speed below 20 km/h and pass smoothly to avoid sudden braking; regular maintenance can prevent unexpected costs. Saving money while ensuring peace of mind is better than risking major trouble for temporary convenience.
During a heavy rainstorm, I was in a hurry and drove through a waterlogged area, resulting in water entering the engine, causing it to stall and leaving me stranded. I waited in the rain for two hours for a tow truck, and the repair cost me 2000 RMB. Now, whenever it rains, I make sure to avoid waterlogged areas, either slowing down or taking a detour. Safety is more important than anything else.
