Safe driving techniques on flooded roads

The rainy season is approaching with long and heavy rain that makes the roads in the city very easily flooded. So you need to equip yourself with the ability to drive cars when flooded roads to avoid the situation of road dead and traffic accidents.

Driving skills are safe when it rains and flooded roads

With the state of potholes, elephants, gas pipes . of roads in urban areas today, when flooded, they will become 'traps' for drivers because they cannot see the road surface, in addition to moving when rain will reduce the ability to observe signs and moving vehicles. Therefore, when moving in this condition, please note the following points:

1. Select the vehicle to run in the middle of the lane to avoid the flooded water

Walking in the middle of the road helps to avoid deep water.

In all pavement designs, the center will be the highest and gradually decrease when outside, so when the car goes closer to the middle of the road, it will limit the car to be deeply inundated. going into potholes, elephant drives or manholes will be high and can suddenly cause deep flooding of the car which can cause death.

2. Always go on the low and even number of the gas pedal when traveling on flooded roads

When traveling in a low-numbered hand, it is easy to overcome obstacles that are accidentally encountered but the driver cannot observe. Always turn on the gas pedal or increase the throttle when it is necessary to pass through sections that are overflowing the exhaust, as the exhaust air will then create a large thrust to prevent water from getting into the exhaust pipe. If you can't go fast, you can keep the brake pedal but still pedal the accelerator. For cars with floor numbers, it is advisable to leave the number 1, and with automatic vehicle numbers, there are numbers D1, D2 . please return to D1.

Note: Absolutely do not reduce the gas when the water is overflowing the exhaust pipe because reducing the gas will reduce the thrust of the exhaust gas flow, which can make the water easily inside the exhaust pipe.

3. Go slowly and observe the vehicle ahead

This will make it easier to control the vehicle while observing the cars ahead so as to avoid the elephant and potholes that the car ahead of you.

4. Do not go near big trucks

Vehicles with large loads will create sudden big waves, which can flood the intake pipe or exhaust pipe causing death. Even when it is raining but not flooded, it is not recommended to go near these vehicles because it creates water flows from large sized wheels that will reduce the driver's visibility. In this case, do not try to overcome when you are not sure about the vision and acceleration of your car.

5. Do not go through when the water level is more than half of the tire

For cars that are not sporty or have a high roar design, when the water level is half of the tire - that is, the limit is not to pass, the safest way is to choose another route to go. Just try to pass if you are sure the water level has not flooded through the air.

6. Do not try to go through when there is a car going in the opposite direction

When going through the deep-water area, you must observe carefully and try to avoid the time when there are cars going in the opposite direction because when two vehicles go in the opposite direction, they will create waves over the capo of the car, causing the risk of water overflowing into the suction throat or lid The machine can wet spark plugs causing the machine to die.

7. Should turn off the air conditioner and unnecessary load

When forced to wade, if the high water level on the shaft is dangerous, turn off the AC switch - air conditioner, go No. 1, run the gas at a moderate level, keep the engine round, go slow and signaling the opposite car to slow down to avoid high waves. If high water reaches the middle of the Padeshock, it is best to turn off the engine, push the car over to a dangerous place, and then check the air filter to see if the water is coming in. After starting the vehicle and moving, remember to gently brake the brake for a while to allow the brake to take effect as normal. For cars with high straws, you still have to be careful because the water can squeeze through the air vents on the car axle, on the body that damages lubricating oil causing damage later. Even simpler is the water will pass through the holes in the floor to wet the interior, short of electronic components installed under the floor.

When driving across a flooded area, you should turn off all unnecessary load equipment such as air conditioning and sound systems . to reduce the load for the engine to avoid sudden death. In addition, the fan of the hot rig is flooded and trying to work can be bent and bumped into the outdoor unit.

8. Do not try to reboot as soon as the engine dies

Do not try to start the engine to avoid hydrodynamics.

When the vehicle enters the flooded road and suddenly dies the machine must be calm to determine the cause of the death, if it is determined that the engine is due to the water entering the engine, it is absolutely forbidden to restart the engine because not only can the engine fail The engine will be able to jam the piston and bend the handle.

Also, observe if the water level crosses the edge of the floor, if it is higher, absolutely do not open the door, as the water will spill inside and will damage electronic systems and internal materials. furniture such as felt, leather, wood .

Note: when having to call for rescue to tow the vehicle, with 4-wheel drive vehicles full-time, it must be transported by specialized vehicle, not using forklifts and tractors because it can damage the powertrain. Some 4-wheel drive vehicles full-time in Vietnam such as: Mercedes Benz 4Mactic drive type; Hyundai Santa Fe 4 wheel drive 4 × 4; Daewoo Winstom 4 × 4; Acura MDX; Lexus AWD types like GS300, GS350; Nissan Murano; Infiniti FX35, FX45, BMW X5, X3 .

9. Check engine oil, bridge oil, brake oil, taper oil

Even if you have gone through the deep flooded road, you should check the engine oil, oil, oil, brake fluid to see if water is coming in. It can be observed with the naked eye, if the oil has unusual color, it is recommended to replace the new oil because when the oil is mixed with water, it reduces the lubrication ability (engine oil, bridge oil) and the transmission capacity (brake fluid, taper) affects the life expectancy as well as the working quality of the systems.

10. Always keep a phone number of traffic rescue in the directory for use in case of necessity
