This last month of the year is turning out to be quite unusual in terms of weather conditions. Although at the moment temperatures are higher than normal, fog is present in some provinces, which persistently can make traffic dangerous.
Given poor visibility, many drivers use fog lights without taking into account that, when they are not really necessary, they can cause dazzling to other drivers. For using them incorrectly we can also receive a fine of up to 200 euros. That is why it is important to pay close attention and follow the rules of the DGT.
According to the Traffic Regulations, fog lights can only be used in case of fog, very heavy rain, storm, heavy snowfall or dust cloud. Regarding the front light system, it says that, when there are conditions of low visibility due to fog, heavy rain or a cloud of dust, even during the day, you must have the lights on, whether fog, dipped or long-range, and clarifies that the fog light can only be used in those cases.
They may also be used on narrow roads with many curves, meaning those that, having a road width of 6.50 meters or less, are marked with signs indicating a succession of curves close to each other.
Regarding the rear fog light, it says that it can only be used when weather or environmental conditions are “especially unfavorable.” This means thick fog, very heavy rain, heavy snow, or dense clouds of dust or smoke.
To avoid a fine, but above all to avoid causing inconvenience to the drivers with whom we share the road, we have to avoid using the fog lights in light rain conditions, since the strong brightness they produce is amplified by the drops that are generated. They deposit on the windshields of other drivers, causing discomfort to their visibility.
To operate these lights, the control controls are usually next to those for the high/low beams, but also on a separate button located on both the center console and on the sides. That is why it is advisable to read the car’s instruction manual and memorize how to put them on and take them off, so as not to have doubts or take your eyes off the road if we are surprised while driving by a fog bank and we do not know its location.
Front fog lights are used in conditions that significantly reduce visibility, isolated or together with short- and long-range fog lights. It is not mandatory and not all vehicles are equipped with it. They can also be used at night on narrow roads (less than 6.5 m wide) with successive marked curves. Poorly used, it dazzles from the front and is reflected in the rearview mirrors.
As for the rear fog light, it has a deep red color, to make the vehicle more visible from behind. We can equip one, on the left or in the center; or two, on the outer edges. It is mandatory for cars (except motorcycles), only in unfavorable conditions: with thick fog, very heavy rain or heavy snowfall. It must be turned off during traffic jams or if the fog disappears, so as not to dazzle the drivers behind you.
