Is it advisable to keep the vehicle's interior light on while driving at night on a poorly lit road?

Question

DentroTest · Accepted Answer

It is not advisable. Although not explicitly prohibited by traffic regulations, turning on the interior light at night creates a detrimental light contrast. This causes two main negative effects: 1) The driver's pupil constricts upon detecting light inside, reducing the ability to see in the darkness outside (visual acuity). 2) Reflections occur on the windshield and windows (mirror effect), hindering the view of the road, signs, and other road users. Therefore, it should only be used briefly if strictly necessary and safe.
