A car without front fog lights travels through fog or smoke that significantly reduces visibility. Main beam could dazzle other users. Which main lighting must it use?

Correct answer

Dipped headlights

Use dipped headlights, together with the applicable position and registration-plate lights. Article 106 allows front fog lights, dipped headlights or main beam in these conditions, but this car has no front fog lights and article 102 requires changing from main beam when it could dazzle. Front fog lights are not compulsory on every car. Rear fog lights are used only in particularly adverse conditions, such as thick fog or dense smoke, rather than any fog. Brake lights do not replace driving illumination.
