What are the precautions for vehicles passing through waterlogged roads?

Precautions for vehicles passing through waterlogged roads: 1. Slow down: Regardless of the road width or condition, drive slowly in the rain, always observe the distance between vehicles ahead and behind, and be mentally prepared to take various emergency measures. Visibility is low in rainy conditions, and the vehicle's emergency performance, such as braking distance, is reduced. Therefore, slow down in advance to leave enough time and space to handle situations and ensure safety. 2. Maintain distance: Rainy conditions obstruct visibility, so it's important to maintain a safe distance between vehicles and continuously monitor the distance ahead and behind. Stay especially far away from large vehicles, as they can block your view, and the water depth they can pass through may not be safe for smaller vehicles. Additionally, large vehicles can splash water, disrupting smaller vehicles. 3. Use fog lights in rainy conditions: Make full use of fog lights to enhance driving safety in the rain. If necessary, turn on hazard warning lights to ensure that vehicles behind are always aware of your movements. 4. Do not restart the engine if it stalls: In heavy rain or storms, some road sections may become severely waterlogged in a short time. If you must drive through water, use a low gear and maintain a steady speed. If the vehicle stalls, do not attempt to restart it immediately, as this may cause severe engine damage. Instead, contact a professional repair shop promptly. Only after a technician has inspected the vehicle and confirmed it is safe should you restart it.

When driving through flooded roads, I usually first assess the water depth—generally, it shouldn't exceed half the height of the wheels, otherwise water can easily enter the engine. It's best to stop and observe or get out to measure with a stick. Then, use a low gear, first or second gear, and maintain a steady speed to drive slowly, avoiding sudden acceleration or braking to prevent stalling. If the car stalls midway, never restart it, as water entering the engine could cause irreparable damage. After passing through, immediately check if the brake pads are soaked—lightly applying the brakes a few times can help dry them. During heavy rain, if water gets into the car, promptly dry the carpets to prevent mold. Different vehicles require different attention: small cars with low ground clearance need extra caution, while SUVs are better but shouldn't be taken lightly. In short, safety comes first—if unsure about the water depth, it's better to detour than take risks, as this is much cheaper than repair costs.

From my experience, do a quick check before wading: ensure the vehicle's exhaust outlet is above the water level, and the air intake isn't too low, otherwise sucking in water can cause serious trouble. Maintain walking speed while passing through, keep the throttle steady to avoid wave impact or excessive splashing. Use a low gear to maintain power, while keeping an eye on the water level changes. If the car starts to float, stay calm, keep the steering straight and avoid sudden turns. After wading, immediately check the electrical systems—whether the lights and door locks are malfunctioning, and ensure the battery box isn't flooded. Additionally, washing the car body is crucial, as debris in dirty water can corrode the chassis. Off-road vehicles can raise their suspension, but don’t rely solely on this. Regular maintenance can prevent problems before they arise. As for wading, it depends on weather conditions—avoid it during heavy rain if possible.

When driving through water, I focus on simplicity and safety. First, stop to check the water depth: it should not exceed the center of the wheels. Then, proceed slowly, maintaining a steady speed without stopping. If the engine stalls, stay in the car and wait for help—do not attempt to restart. After passing through, inspect the undercarriage and electrical equipment. On rainy days, avoid recklessness; taking a detour is safer and reduces the risk of engine damage.

When encountering waterlogged urban roads, I proceed with utmost caution. First, assess the water flow speed and depth: if it reaches halfway up the tires, it's dangerous. Proceed steadily in the lowest gear while maintaining firm steering control to prevent loss of control. Keep all windows fully closed and avoid opening doors in flooded areas. After wading through water, brakes may slip, so gently apply them to restore traction. If water enters the cabin, turn on the air conditioning to dehumidify, otherwise it may cause odors. Make it a habit to take detours during heavy rain, regardless of whether the car is new or old, as water exposure can easily damage electronic components.
