If you park your car at night on an unlit road, are you obliged to use position or parking lights?

Yes, when parked on an unlit road in conditions of insufficient visibility, the driver is obliged to switch on the position lights or parking lights. This is crucial for safety, as it signals the vehicle's presence to other road users and prevents a collision. This duty is specified in Art. 52 para. 1 of the Road Traffic Act.
