Question

DentroTest · Accepted Answer

According to General Traffic Regulations, it is mandatory to use dipped beam (low beam) headlights whenever driving through tunnels, underpasses, or road sections affected by the 'Tunnel' sign (S-5), regardless of the time of day or the quality of artificial lighting. The goal is to counteract the sudden change in brightness (black hole effect) to see and be seen. The other options are incorrect: lights are not required in well-lit urban areas during the day, and speed on highways does not by itself dictate the use of lights.
