Have you heard about water hammer? Water hammer is the result of a pressure surge, or high-pressure shockwave that propagates through a piping system when a fluid in motion is forced to change direction or stop abruptly. This shockwave is also commonly referred to as a hydraulic shock or hydraulic surge, and may be characterized by a marked banging or knocking sound on the pipes immediately after shutoff.This can happen if you pass through a flood with a water level of more than 50 cm
This term is also called hydrolocking, where water enters through the air filter so that the engine stops suddenly. The second problem can also be caused by water entering the lubrication system so that it mixes with the oil.

The functions of the hazard lights

1. Use in an emergency
In accordance with the Law on Road Transport Traffic (LLAJ) Article 121 paragraph 1, every motorized vehicle driver is required to install a safety triangle, a hazard warning signal light, or other signals when stopping in an emergency situation on the road. For example, your vehicle stops due to an emergency during a breakdown, a traffic accident, or other conditions such as a tire that needs to be replaced. If you are in an emergency situation, then immediately pull over and press the hazard lights.
2. As a warning sign
The next function of the hazard light is as a warning sign. While driving on the road, there are times when you meet an emergency situation that can threaten your safety.
For example, your brakes don't work, or someone suddenly crosses the road, or other conditions that require you to stop suddenly in the middle of the road.
3. Not for Use in Bad Weather
A misunderstanding about the function of hazard lights is to use them in bad weather such as heavy rain or heavy fog.
Turning on the hazard lights when the weather is bad can actually endanger safety. This is because when the hazard light is active, the automatic turn signal cannot function. If you want to give a turn signal, the vehicles behind you will have a hard time understanding it.
4. Not a signal when entering the tunnel
Turning on the hazard lights when entering the tunnel should be avoided. The hazard light signal will actually confuse the driver of the motor vehicle behind you. When entering a dark tunnel or passage, simply turn on the main light or evening light to maintain visibility.
5. Not for convoys
There are still many car drivers who misinterpret the use of hazard lights. One of them is to use hazard lights during convoys or convoys.
It can be concluded that the actual hazard light function should only be used in an emergency, such as when an accident occurs or the car suddenly breaks down. Avoid turning on hazard lights without a clear situation because it can endanger safety.
