What minimum section of the road ahead of the truck should be lit by properly-adjusted low-beam lights?

In accordance with the regulations concerning the technical condition of vehicles, dipped headlights must be set to provide sufficient illumination of the road for a distance of at least 40 metres ahead of the vehicle. This range is essential for safe driving, enabling the driver to spot an obstacle in good time and to react appropriately. At the same time, their asymmetrical design prevents dazzling oncoming drivers.
