What Are the Levels of Vehicle Flooding?

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.

Which has better penetration: fog lights or hazard warning lights?

Theoretically, hazard warning lights (flashers) have a stronger warning effect. The differences between fog lights and hazard warning lights are as follows: Different usage methods: Fog lights provide supplementary lighting in rainy or foggy weather. When visibility is obscured by heavy fog, the light intensity is just right, allowing fog lights to enhance recognition. Hazard warning lights are used to alert passing vehicles when the car has a malfunction or is involved in a traffic accident. Turning on the hazard warning lights serves to remind other drivers to pay attention to safety. Different applicable scenarios: Front fog lights are installed at the front of the car, slightly lower than the headlights, and are used to illuminate the road during rainy or foggy conditions. Fog lights are suitable for severe weather conditions such as heavy rain, fog, snow, or dust. The visible range of fog lights is approximately 100 meters. When visibility drops below 100 meters, fog lights must be turned on, and drivers should reduce their speed accordingly. Hazard warning lights serve a specific alert and warning function. If a vehicle breaks down and cannot move (or can only move at low speed, including when being towed), hazard warning lights must be activated to alert vehicles behind. Additionally, a triangular warning sign should be placed 200 meters behind the vehicle (for vehicles that cannot move) to warn approaching traffic.

Why Can't the Truck Start?

It may be due to insufficient battery voltage. Insufficient voltage doesn't mean there's no power; the horn and lights may still work, but it can't power the starter. Here are some reasons why a vehicle with power can't start: 1. First, check if there's insufficient fuel: Without the power source 'gasoline,' the car naturally won't start. If the issue is low fuel, it's advisable for the driver to regularly monitor the fuel gauge. When it nears the warning level, refuel promptly instead of waiting until the tank is empty. This practice is harmful to the engine and can shorten its lifespan. 2. Incorrect gear position can also prevent the car from starting: Generally, the correct gear positions for starting an automatic transmission vehicle are 'P' or 'N.' If the driver accidentally leaves the gear in 'R' or another position, not only will the car fail to start, but it also poses a safety hazard. 3. Circuit or electronic failure: These issues can occur suddenly without any warning. Circuit failures include blown fuses, open high-voltage coils, open low-voltage circuits, detached central ignition wires, leaking distributor rotors, or damaged spark plugs. Electronic failures mainly refer to malfunctions in the central computer control board. 4. Stalling caused by fuel system issues: Symptoms often include engine weakness and a spongy accelerator pedal. Potential fuel system problems include fuel pump failure, blocked fuel lines, clogged fuel filters, carbon buildup on spark plugs, or damaged injectors. Sometimes, the tank might be empty without the driver realizing it. Adding a few liters of gasoline can resolve all these issues.
