When can I use the car's double flash? Can I use the double flash when driving in fog?

We often see some motor vehicles turning on the double flashes and speeding along the road, which is usually an emergency. You cannot turn on the double flashes casually during normal driving, but you can turn on the double flashes in foggy, rainy or snowy weather to warn other vehicles.

When to use the car's double flash

The full name of the double flash is hazard warning flasher. It is illegal to use the double flash without permission, and serious penalties will be deducted. The double flash can only be used in some special circumstances:

1. When a vehicle breaks down, first turn on the hazard lights and put a warning sign behind the vehicle before taking any action;

2. When driving on the highway, turn on the hazard lights and slow down when encountering bad weather, such as heavy fog, rain, snow, sand, hail, etc.;

3. When towing a faulty motor vehicle, both the front and rear vehicles need to turn on the hazard lights to alert passing vehicles and pedestrians;

4. With approval from relevant departments, the motorcade can turn on the hazard lights when traveling. It is actually wrong to see motorcades during weddings or funerals turning on the hazard lights all the way, but this situation is generally not checked.

The hazard lights should not be used indiscriminately as they will cause trouble to other vehicles driving normally. Especially for novice drivers, they should pay more attention to the road conditions and they will become familiar with them in a few days.

Can I use the hazard lights when driving in fog?

First of all, you must not turn on the high beam! When you turn on the high beam in foggy weather, diffuse reflection will form, which will not only make it difficult to see far, but also cause a white mist in front of the car, making it even more unclear and more likely to cause an accident!

When the visibility is less than 100 meters, we need to turn on the fog lights, low beam lights and width lights, and also use the double flashes, so that other cars can notice you more easily!

What does it mean when a car flashes twice?

The meaning of double flashing car headlights is different in different situations!

Flash: Generally it means giving way, thanking, and reminding. When meeting other vehicles in complex road conditions, flashing usually means letting the other party go first. When the traffic light is green, if the car in front does not start in time, flashing the high beam means reminding. In addition, flashing also means smiling and thanking. It can be used in general situations!

Flash twice: Generally, it has the function of reminding or warning, and its meaning is slightly stronger than flashing once! For example, if the other car occupies your lane when meeting, then flashing twice means that you should pay attention to give way. For example, if the other car is driving with high beams at night, flashing twice means reminding the other party to switch the lights. Sometimes, if the car in front does not move on the green light for a long time, then flashing twice means a reminder, which is stronger than flashing once.

In addition, the brake lights will be used in conjunction with the double flashes. As a car behind you, once you see the brakes + double flashes, you must slow down and keep a safe distance. By the way, it is not recommended to use flashing brake lights, as multiple flashes will not provide a better warning effect.
