The low-beam headlights (dipped lights) must be turned on during the day on reversible lanes, since these lanes change direction depending on the time of day and require greater visibility to warn other drivers of your presence. This measure is mandatory on roads with reversible lanes to improve safety and prevent confusion among road users.
