7 Emergency exit of the driver's cab
7.1 The driver's cab at the end shall be provided with at least one door or one

door is in danger of obstruction (such as luggage, passengers), the door
should be designed as a sliding plug door or a door that can rotate both
inward and outward.
c) The crew members shall be able to evacuate from the emergency exit
safely and without difficulty; the distance between the emergency exit and
