The province of Alicante woke up this morning shrouded by a thick fog that covers several municipalities, just like it happened yesterday in Benidorm, where the mist devoured the iconic skyscrapers. This coastal haze has caused that in many parts of the roads visibility is greatly reduced. Faced with this situation, many drivers wonder how to drive with this weather phenomenon that hinders circulation.

On days like this it is important to take a series of measures that guarantee safety. How should we drive if we encounter thick fog? What lights should we use? Here are some tips for driving in fog:

When do I have to put the fog light?

The rear fog lights they are the only ones that are available on any vehicle on the standard market. However, lighting front fog it is only available on some models. This is so because rear fog lights son obligatory and manufacturers must incorporate them into their vehicles by law. On when we should use these headlights the General Traffic Regulations explain that we will use the rear fog lights in case of heavy rain, as well as in situation of thick fog or intense snow and, on the other hand, if there were dust or smoke that obscures visibility. This serves so that other drivers can see the position of our car, however, the front, point lower and closer, so that we can see correctly what we have just ahead, but they can dazzle other vehicles so it is important to use them only when strictly necessary. Keep in mind that they should be turned off once you leave the foggy section so as not to disturb other drivers.

You must remember that the warning light corresponding to the rear fog lamp It is the one that focuses to the right.

Safety distance

It is also essential increase safety distance since the fog brings humidity with it that soaks the asphalt and makes it more slippery. Thus, you will avoid a braking or a crash in chain with the risks that this implies.

Likewise, it is advisable that you keep an eye on the markings and graffiti on the asphalt and on other vehicles. In this way, and without forcing the march, you can have a reference when driving with reduced visibility.

Speed

To drive comfortably and without taking risks, it is also necessary to reduce the speed of circulation.

Keep calm

Finally, if you don’t see yourself capable of driving in fog and you get very nervous at the wheel, the best thing you can do is go out at the first rest area or detour you see and wait until the cloud lifts. And it is that the phenomenon that is taking place in the province of Alicante is known as “littoral fog” and disappears as the day progresses. But, What is the cause of this phenomenon that is taking place on the coast of the province? The answer is very simple: it is about advection fog, which occurs due to the advance of a warm air mass over a cool Mediterranean given that now is when sea temperatures are lower, as explained by the Climatology Laboratory of the University of Alicante.

Likewise, from the AU body they point out that the temperature difference between sea and air it allows the humidity contained in the air mass to condense in its area closest to the sea surface.
