Fog is one of the meteorological phenomena that can most impress behind the wheel, since depending on its density it makes it practically impossible to see anything through the windshield. Although vehicles have specific lights to activate when driving under these circumstances, it is sometimes safer to stop the vehicle and wait for the fog to clear.
But in addition, the fog does not only affect visibility, but also to the adherence of the wheels to the asphalt, since this phenomenon requires humid conditions to occur. In addition, when it occurs in winter, cold and the danger of water droplets freezing on the asphalt is added to the equation.
For both reasons, the General Directorate of Traffic recommends extreme precautions in case of driving in fog, whether it is more or less dense. In the event of encountering a fog bank, these are the steps to follow:
- Adapt to speed. Downshifting on interurban roads limits damage in a collision and allows more reaction time.
- Increase the safety distance with the vehicle that precedes us.
- Turn on the correct lights. The crossover and the front fog lights. If the bank is very thick, the rear ones will have to be connected.
- Activate the windshields if deemed necessary.
- Do not brake or accelerate sharply. This prevents collisions and chain hits.
What tricks can help us to drive more safely in low visibility? It is best to follow the painted road signs as they reflect the light from the headlights and are always visible. They are marking the road and the curves of the lane, so avoid exits from the road. It is also possible, without forcing the march, to take as a reference the vehicle that circulates in front of us. It will give us clues about changes in the road.
What is it never to do? Connect the main beams. The light will bounce off the droplets that form the fog bank and reflect, causing worse vision and glare.
