58. Emergency exit
An emergency exit is a marked escape route that allows road users to leave a tunnel or other enclosed traffic facility during a serious incident such as a fire, smoke development or another emergency. Emergency exits lead towards a safer area separated from the immediate danger.
In an emergency, occupants should leave their vehicle when evacuation is necessary and follow the emergency-exit signs and instructions. They should move away from the danger rather than remaining inside the tunnel or returning to their vehicle.
