What precautions should be taken for vehicles during heavy rain?

Do not compete for the right of way when driving in the rain. Pedestrians and cyclists often rush and compete with motor vehicles for the road. Maximum wading depth: The maximum wading depth refers to the maximum depth that can be safely traversed under safe driving conditions, also known as the safe depth. It is also an important indicator for evaluating a vehicle's off-road capability. The greater the maximum wading depth, the stronger the vehicle's ability to traverse water. Under full load conditions: The Prado has a minimum ground clearance of approximately 190mm when fully loaded. The Prado's maximum wading depth of 700mm is a relatively theoretical figure. It is recommended to wade at around 600mm. Exceeding 700mm may cause water to reach connectors, sensors, and other electronic components, posing a risk to property safety. Air intake height: The height of the air intake determines the vehicle's wading depth. The primary factor in determining a car's wading depth is the height of the engine's air intake. Generally, the engine's air intake is located on the upper side of the central part of the grille. If the air intake is below the water level during wading, water will be sucked into the engine's cylinders. Since water cannot be compressed like air, it can cause severe damage to the engine's mechanical components (such as connecting rods, pistons, crankshafts, etc.). Therefore, the wading depth must never exceed the height of the engine's air intake.

I drive long-distance deliveries all year round, and I really have to stay extra alert when driving in heavy rain. I remember last year on the highway when I suddenly encountered a downpour—couldn't see anything ahead, but luckily the windshield wipers were brand new. I reduced my speed to below 40 and maintained double the usual following distance because braking on wet roads can easily cause skidding. I kept the headlights and fog lights on to make sure others could see me. The tire tread depth must be sufficient, or the car might drift when turning. When encountering puddles, go through them slowly without accelerating—water entering the engine would be a big problem. If the windshield fogs up, turn on the AC to defrost it. Keep towels and a small shovel in the car for quick cleanup. Arriving safely is a hundred times more important than rushing.

I have two kids, so I'm extra cautious when driving to pick them up from school during heavy rain. First, I check if the wipers can clear the rainwater properly; otherwise, it's hard to see the road conditions. I reduce my speed by half and maintain a following distance of at least three seconds to prevent sudden braking by the car ahead. I turn on all the lights to make sure the cars behind know my position. I avoid driving through deep water to prevent stalling. After parking, I wait for the rain to ease before opening the car doors. The air conditioning's defogging function is a must-use, or the windshield will fog up completely. Safety comes first when traveling with kids—if the road conditions feel too bad, I simply wait at a convenience store. Regular maintenance of tires and wipers is essential.

I usually enjoy tinkering with cars, and the key to driving in heavy rain is preventing malfunctions. The wipers should be newly replaced to ensure smooth wiping; tires with excessive wear will skid on wet roads; brakes need to be sensitive to prevent rear-end collisions. Turn on the lights to enhance visibility. Avoid rushing through puddles to prevent electrical short circuits. Use the air conditioner to defog and avoid blurred vision. Before each rain, quickly check that the drainage pipes aren’t clogged. Remember, driving slowly is the golden rule—safety is worth more than anything.

I commute for an hour every day, and heavy rain is the most annoying. Check the weather forecast before departure to avoid peak rain periods. Keep the speed under 60 and maintain a generous distance. Turn on all lights including hazard lights. Use the air conditioner to defog the windshield. Slowly go around or gently pass through puddles to avoid splashing others. Keep an umbrella and a power bank in the car in case of a breakdown. Check the tires every six months to ensure they are anti-slip. Be extra careful on narrow city roads.

As a car enthusiast, driving in heavy rain starts with preparation. Before the rain, check the wiper blades and tire tread; while driving, slow down, especially on highways. Keep your lights on to ensure visibility. Avoid large puddles to prevent engine damage. Keep the defogging function of the air conditioning on to prevent blurring. Carry an emergency kit in the car, including a flashlight. Patience is more important than any skill—when road conditions are bad, pull over and rest nearby. Remembering these habits can reduce 80% of the risks.
