What Are the Levels of Vehicle Flooding?

[DelElaina]

Below is the classification of vehicle flooding levels: 1. Flooding Level 1: Water has just reached the vehicle's chassis, and the floor may become damp, but the likelihood of significant water ingress is low, with minimal impact on the vehicle's electrical equipment. 2. Flooding Level 2: Water reaches halfway up the wheels. Due to the vehicle's incomplete sealing, water will begin to enter the interior. For lower sedans, the water level inside may affect the seat adjustment motors and electrical components such as heating and ventilation. 3. Flooding Level 3: Water almost completely submerges the tires. At this point, the water level inside will fully cover the seat cushions and the central armrest area, affecting a large number of electrical devices. 4. Flooding Level 4: Water reaches the engine hood. The interior water level rises to the dashboard, and the headlights and the engine's intake pipe in the engine compartment begin to take in water. 5. Flooding Level 5: Water completely submerges the engine hood. At this stage, almost all electrical devices inside the vehicle will be affected by the water. 6. Flooding Level 6: Water submerges the roof, affecting the headliner and sunroof module, with no interior component spared from damage.
