Explanation

FRONT FOG LIGHT: - Fitting and using it are NOT compulsory. - It must be white or selective yellow. - It may be used, voluntarily, in fog, heavy rain, snowfall, clouds of smoke or dust, or similar conditions. - It may also be used on narrow roads with many bends, that is, roads with a carriageway 6.5 m wide or less that are signposted with ‘dangerous bends’ signs. REAR FOG LIGHT: - Fitting and using it are compulsory. - It must be red. - It must be used in DENSE fog, VERY heavy rain, HEAVY snowfall or THICK clouds of smoke or dust. During the day, the front fog light may be on with just the sidelights, but it may also be used together with dipped headlights or main beam. At night, it must be used at least with dipped headlights. During the day, the rear fog light must be used at least together with the front fog light or dipped headlights. At night, at least with dipped headlights.
