Tips for driving safely through flooded areas
(Baonghean.vn) - During heavy rains, localized flooding occurs in many areas. While high-clearance vehicles can pass through, low-clearance vehicles pose a concern for drivers. To safely navigate flooded areas, the following points should be noted.
1. Observe the vehicles ahead.Only proceed if the water level is no more than half the height of the tires. If the water level rises above half the tires, there's a high chance of water flooding the passenger compartment and damaging the electrical system under the vehicle.
When the floor of a vehicle is submerged in water, there is a risk of electrical short circuits leading to damage to the internal electrical system and affecting the vehicle's equipment.

2.If traffic conditions permit, driveYou should walk in the middle of the road.Because this is always the highest point of the road surface, this will help lower the water level and reduce the risk to your vehicle.
3. Always maintain a safe distance from other vehicles.And stay away from heavy vehicles because other vehicles, when moving, will create large waves that can splash over your car's hood and potentially cause water to enter the air intake and directly into the engine, resulting in "hydro-locking".
4.When driving through a flooded area,You should maintain a steady throttle and choose a low gear.If it's a manual transmission, you should use gears 1-2. For automatic or semi-automatic transmissions, you should shift to D1 or switch to manual mode and drive in gears 1-2.
Turn off some appliances such as air conditioners and entertainment systems to reduce the load on the engine and also to prevent short circuits in case of water ingress.

5. Absolutely do not accelerate and speed through flooded roads.Because of the risk that water could be pushed under pressure onto the hood and into the engine's air intake, causing a phenomenon called hydrolock.
Experienced drivers often share a common piece of advice: before driving through flooded areas, disconnect the air intake pipe at the front of the vehicle to draw air directly from the engine compartment (at the highest point) without going through the vehicle's intake system (at a lower point); after passing through the flooded area, reinstall the engine air filter. This method can prevent water from overflowing the hood and being sucked into the air intake, causing "hydro-locking" of the engine.

- 6.After passing through the flooded section of road, it is necessary toDriving while constantly applying the brakes.Allow the water in the brakes to drain away from the brake discs, to prevent brake seizure after being left overnight.
- Remove any trash or leaves from the radiator, as it acts as a barrier, trapping a lot of debris in the water when driving through flooded areas. Finally, check the engine and undercarriage to ensure they are clean and free of any abnormalities.
