Main beam headlights must be switched to dipped beam at least 250 m before an oncoming vehicle, and also when they may dazzle other drivers, in particular those moving in the same direction.

The lights must also be switched at a greater distance if the driver of the oncoming vehicle indicates this need by periodically switching the headlights.

If visibility in the direction of movement deteriorates due to the headlights of oncoming vehicles, the driver must reduce speed to one that does not exceed a safe speed under the conditions of actual road visibility in the direction of movement, and in case of dazzling - stop without changing lanes and switch on the hazard warning lights. Resuming movement is permitted only after the negative effects of dazzling have passed.

Front fog lamps may be used in conditions of insufficient visibility either separately or together with dipped or main beam headlights, and during darkness on unlit road sections - only together with dipped or main beam headlights.
