Water reaching half of the tire without submerging the engine or transmission does not count as a water-damaged vehicle. Here are the relevant details: Introduction to Water-Damaged Vehicles; A water-damaged vehicle refers to a car that has been submerged in water, typically meaning the engine or transmission has been soaked, with the water level exceeding the wheels and vehicle seats, and the vehicle's underbody components being in prolonged contact with water. Such vehicles pose significant risks, as the electrical circuits are prone to short circuits and fires. Hazards of Water-Damaged Vehicles: Water-damaged vehicles can be repaired to some extent, but even after repairs, serious hidden dangers remain. The longer the immersion time, the higher the likelihood of malfunctions. It's like a watch falling into water—even if it's disassembled and dried, the watch will still malfunction and cannot be completely repaired.

I've encountered flooded roads several times while driving, where the water reached about halfway up the tires. This usually doesn't qualify as a strictly defined flooded car, as flooding typically refers to water entering the cabin or engine compartment, causing damage to the electrical system or engine. If the water level only reaches the middle of the wheels, approximately 15-20 cm deep, it may not necessarily allow water to enter the interior, but it should never be ignored: it can affect brake response or cause tire slippage, increasing the risk of accidents. My advice is to stop and observe the water level when encountering such situations, avoiding high-speed water crossings. If you must proceed, check afterward for any wet traces on the floor and undercarriage. Safety first—don't risk rushing through and causing a major disaster, which could double repair costs and damage the vehicle's lifespan.

Having repaired too many cars, water reaching half the height of the tires doesn't count as a typical flooding incident, but if water seeps into the chassis or wheel axles, it's borderline. I've seen many car owners think it's a minor issue, only to end up with corroded electrical wiring or rusted wheel bearings, making repairs a headache. When the water depth is about 10 centimeters or more, it depends on the vehicle's sealing: older cars or those improperly modified are more prone to water ingress. It's advisable to immediately dry the car body and inspect the engine compartment after wading through water; long-term parking in such conditions can lead to water accumulation in the wheel wells, accelerating wear. Developing preventive habits is far better than dealing with the aftermath.

The definition of a flooded car is when water invades critical areas of the vehicle cabin, such as exceeding the sill line or causing system short circuits. Water reaching half the tire depth (around 15 cm) may not meet that standard unless there is seepage at entry points like door gaps. I've experienced similar situations while driving—the key judgment is whether the water only affects the outer wheel areas, which doesn't qualify as full vehicle flooding. However, brief wading with aggressive operation may damage the engine or braking system. Prompt drying treatment can prevent major issues.
