planes through their centres of area is not less than 40% of the overall length of the
passenger compartment measured parallel to the longitudinal axis of the vehicle.
In the case of an articulated vehicle, this requirement shall be fulfilled if two doors of the
different sections are separated such, that the distance between the doors is not less than
40% of the overall length of the combined passenger compartment (all sections). In either
case, if one of these doors forms part of a double door this distance shall be measured
between the doors which are furthest apart.
5.6.2.3. The exits shall be placed in such a way that their number on each of the two sides of the
vehicle is substantially the same.
5.6.2.4. At least one emergency exit shall be situated either in the rear face or in the front face of the
vehicle respectively. For Class I vehicles and for vehicles with a rear part permanently
closed off from the passengers' compartment, this provision is fulfilled if an escape hatch is
fitted.
5.6.2.5. The exits on the same side of the vehicle shall be suitably spaced out along the length of
the vehicle.
5.6.2.6. A door shall, provided that it is not a service door, be permitted in the rear face of the

cover over the control, shall be indicated to the driver both audibly and visually, and
5.6.5.1.7. In the case of a driver-operated door which does not comply with the requirements of
5.6.5.6.2 below, the controls shall be such that after they have been operated to open the
door and returned to their normal position, the door will not close again until the driver
subsequently operates a closing control.
5.6.5.2. A device may be provided which is operated by the driver from his seat to deactivate the
outside emergency controls in order to lock the service doors from outside. In this case, the
outside emergency controls shall be reactivated automatically either by the starting of the
engine or before the vehicle reaches a speed of 20 km/h. Subsequently, deactivation of the
outside emergency controls shall not occur automatically, but shall require a further action
by the driver.

to be opened from outside, also on the outside of the vehicle; the indicator (e.g. illuminated
push button, illuminated sign) shall be on or adjacent to the door to which it relates.
5.6.6.1.4. In the case of direct actuation by means of a switch the functional state of the system shall
be clearly indicated to the driver, for example by the position of the switch or an indicator
lamp or an illuminated switch. The switch shall be specially marked and arranged in such a
way that it cannot be confused with other controls.
5.6.6.2. Opening of automatically-operated service doors.
5.6.6.2.1. After activation of the opening controls by the driver it shall be possible for passengers to
open the door as follows:
5.6.6.2.1.1. From inside, for example by pressing a push-button or passing a light barrier, and
5.6.6.2.1.2. From outside, except in the case of a door intended only as an exit and marked as such, for
example by pressing an illuminated push button, a push button beneath an illuminated sign,
or a similar device marked with a suitable instruction.

5.6.7.4. Emergency doors fitted to the side of the vehicle shall be hinged at their forward edge and
shall open outwards. Check straps, chains or other restraining devices shall be permitted,
provided that they do not prevent the door from opening to, and remaining open at, an angle
of at least 100°. If a means is provided sufficient to give free passage to the emergency
door access gauge, the 100° minimum angle shall not apply.
5.6.7.5. If an emergency door is located adjacent to a door to a toilet or other internal compartment,
the emergency door shall be proofed against unintentional operation. However, this
requirement shall not apply if the emergency door is locked automatically when the vehicle
is moving at a speed exceeding 5 km/h.
5.6.7.6. If the driver's service door is not readily accessible, in particular if it is necessary to squeeze
between the steering wheel and the driver's seat in order to reach the service door, the
service door shall not be deemed to be an emergency door.
5.6.7.7. All emergency doors which cannot easily be seen from the driver's seat shall be provided
with an audible device to warn the driver when they are not securely closed. The warning
device shall be operated by movement of the door catch and not by movement of the door
itself.

5.6.8.5. The height of the lower edge of an emergency window fitted in the side of the vehicle from
the level of the floor immediately below it shall be not more than 100 cm nor less than 65 cm
in the case of a hinged emergency window, or 50 cm in the case of a window made of
breakable glass.
However, in the case of a hinged emergency window the height of the lower edge may be
reduced to a minimum of 50 cm provided that the window aperture is equipped with a guard
up to a height of 65 cm to prevent the possibility of passengers falling out of the vehicle.
Where the window aperture is equipped with a guard, the size of the window aperture above
the guard shall not be less than the minimum size prescribed for an emergency window.

5.6.10.5. The step shall not be capable of being extended when the vehicle is in motion. If the device
to operate the step fails, the step shall retract and remain in the retracted
position. However, the operation of the corresponding door shall not be hindered in the
event of such a failure, or if the step is damaged;
5.6.10.6. When a passenger is standing on the retractable step, the corresponding door shall be
incapable of being closed. Compliance with this requirement shall be checked by placing a
mass of 15 kg representing a small child, at the centre of the step. This requirement shall
