If you are driving on the road and suddenly encounter heavy rain and there is very deep accumulated water on the road, you can take the following measures :
I. Stay Calm
First of all, stay calm and don't panic. Panic may lead to wrong operations and increase danger.
II. Judge The Depth Of Accumulated Water
1. If the depth of accumulated water does not exceed half of the tire, you can pass carefully. But keep a low gear and high speed, drive slowly and evenly, and avoid splashing water into the engine air intake.
2. If the depth of accumulated water is close to or exceeds the height of the tire, do not take risks to pass. Stop immediately and choose a safe place to wait for the accumulated water to recede or seek rescue !
III. Avoid Entering Unknown Areas
Don't drive into unfamiliar roads or low-lying areas, because the water accumulation in these places may be more serious, and there may be dangers such as potholes and missing manhole covers !
IV. Pay Attention To Observing Surrounding Vehicles
Observe the driving conditions of other vehicles. If a vehicle stalls or is trapped in accumulated water, avoid following its driving route to avoid getting into the same predicament !
V. Prevent The Vehicle From Stalling
1. When passing through a waterlogged section, avoid stopping, shifting gears or braking suddenly in the middle to prevent the engine from stalling due to water intake !
2. If the vehicle stalls in accumulated water, do not start the engine again to avoid causing greater damage. Leave the vehicle immediately and wait for rescue at a safe place !
VI. Ensure Your Own Safety
If the vehicle is trapped in accumulated water, leave the vehicle as soon as possible and take refuge in a place with higher terrain. When leaving the vehicle, pay attention to observing the surrounding environment to avoid being washed away by the current !
In short, when driving and encountering heavy rain and accumulated water, stay calm, judge carefully, and ensure the safety of yourself and the Vehicle !
