# Explanation
When you must stop in a tunnel due to traffic problems, it is essential to maintain the maximum possible distance from the vehicle in front. This allows other drivers to have space to brake and avoid chain collisions, in addition to facilitating the movement of emergency vehicles if necessary. Proximity between vehicles in a tunnel significantly increases the risk of serious accidents.
