Conditions of reduced visibility

Article 106. Conditions of reduced visibility.
1. It is obligatory to use lights when meteorological or environmental conditions exist that significantly reduce visibility, such as fog, heavy rain, falling snow, clouds of smoke or dust or any other analogous circumstance (LST Art 43).
2. In the above cases front fog lights or headlights must be used.
Front fog lights can be used independently or with headlights.
Front fog light may only be used in the above cases or on narrow roads with many bends, i.e. having a road width of 6.50m or less, signed with signals indicating a series of bends, regulated in Article 149.
Rear fog lights may only be used when the meteorological or environmental conditions are especially unfavorable, such as thick fog, very heavy rain, heavily falling snow or dense clouds of dust or smoke.
3. Travelling without the appropriate lights in situations of reduced visibility is a serious offence (LST Art 65.4.e).
