Warning. According to the Road Traffic Regulations of the Russian Federation, fog lights in the dark on unlit sections of roads can only be used in conjunction with low or high beam headlights.

...that's why the glass is often broken by stones flying off the road and bursts from temperature changes when it is flooded with cold water from a puddle while it is on.
But fog lights become indispensable during fog, rain and snowfall, when, unlike low or high beam headlights, fog lights better indicate the boundary of the roadway and the distance to the car in front and eliminate blinding glare in the water.
Warning. According to the Road Traffic Regulations of the Russian Federation, fog lights in conditions of poor visibility can be used either separately or with low or high beam headlights.
