Whenever you are stopped inside a tunnel you must keep the parking lights on. If you anticipate that the stop will be prolonged (more than 2 minutes) you must switch off the engine. You should also activate the hazard warning signal momentarily if the stop is due to congestion, or keep it on if it is due to an emergency.
