Guidelines for using driving lights in heavy rain: Which is more effective, dual flashing or fog lights?

In summer, not only does the high temperature and heat easily affect driving safety, but also the unpredictable weather. As we travel day and night, we inevitably encounter sudden heavy rain. How to use lights when driving in heavy rain is actually a knowledge. Today, we will talk about which is more effective and how to use double flashing or fog lights more reasonably when driving in heavy rain.

1.Manipulation methods and penetration rate:

Firstly, let's take a look at the characteristics and popularity of dual flashing and fog lights. The dual flashing light design of each model is consistent, all using red button type, and is available on each model. Fog lights are more diverse, with paddle type, button type, and knob type being common, which can meet the needs of users with different habits. Although the regulations do not mandate the installation of fog lights, most models are equipped with them, with only a few exceptions for low-end micro card models.

2.The function of truck dual flashing and truck fog lights:

The full name of the dual flashing light is: hazard warning flashing light, which is mainly used in scenarios such as vehicle malfunctions, emergency tasks, and extreme weather driving. The main purpose is to inform other vehicles that we are in an emergency state and pay attention to avoidance.

Fog lights: Fog lights are divided into front fog lights and rear fog lights, and there are also differences in color, mostly using front yellow and rear red. The characteristic is that the light has extremely strong penetration ability and does not produce diffuse reflection reaction due to fog, which can not only remind other vehicles to pay attention to us, but also improve our vision when driving in rainy and foggy weather.

3、 Regulatory requirements for the use of dual flashing and fog lights:

Regarding extreme weather driving such as rain and fog, China's "Implementation Regulations for Road Safety Law" also clearly stipulates:

When the visibility is less than 200 meters, turn on the fog lamp, low beam, clearance lamp and front and rear position lamp, and the vehicle speed shall not exceed 60 km/h, keeping a distance of more than 100 meters from the vehicle in front of the same lane;

When the visibility is less than 100 meters, turn on the fog lamp, fog lamp, low beam, clearance lamp, front and rear position lamps and hazard warning flashing lamps (double flashing lamps), and the vehicle speed shall not exceed 40 km/h, keeping a distance of more than 50 meters from the vehicle in front of the same lane;

When the visibility is less than 50 meters, turn on the fog lights, fog lights, low beam, clearance lights, front and rear position lights and hazard warning flashing lights (double flashing lights), the speed shall not exceed 20 km/h, and drive away from the expressway from the nearest exit as soon as possible.

In addition, there will be corresponding penalty points and fines for using dual flashing lights in violation of regulations. We should pay attention to not turning on dual flashing lights when driving in extreme weather with non visibility below 100 meters, and should promptly turn on fog lights and other light sources to respond.

4. The correct timing for using dual flashing and fog lights:

I believe that after reading the functions and regulatory requirements of dual flashing and fog lights, everyone has a clear idea. The dual flashing function is more extensive and can inform our side of emergency situations. The fog lights are specifically designed for driving scenarios in rainy and foggy weather and low visibility, which is not only convenient for others but also beneficial for driving in rainy and foggy weather. So fog lights are the first choice for driving in rainy and foggy weather.

As our standards for vehicle safety gradually improve, fog lights have become a standard feature on almost every car. However, in rainy and foggy weather, you can still see many vehicles that only turn on dual flashing and do not turn on fog lights. Although the starting point is good, it is actually more effective without fog lights.
