compartment.
7.6.1.9. If a driver's door or other exit from the compartment is provided in the circumstances
described in Paragraph 7.6.1.8 it may only count as an exit for passengers provided:
7.6.1.9.1. It satisfies the requirements relating to the dimensions of emergency door indicated in
Paragraph 7.6.3.1.;
7.6.1.9.2. It fulfils the requirements indicated in Paragraph 7.6.1.7.2.;
7.6.1.9.3. The space reserved for the driver's seat shall communicate with the main passengers'
compartment through an appropriate passage; such requirement shall be deemed to be
fulfilled if the test gauge described in Paragraph 7.7.5.1 can move unobstructed from the
gangway, until the front end of the gauge reaches the vertical plane tangential to the
foremost point of the driver's seat back (this seat being situated in its rearmost
longitudinal position) and, from this plane, the panel described in Paragraph 7.6.1.7.2
could be moved to the emergency door in the direction established by such paragraph
(see Annex 4, Figure 28) with seat and steering wheel adjustment in their mid position.
7.6.1.10. Paragraphs 7.6.1.8 and 7.6.1.9 do not preclude there being a door or other barrier
between the driver's seat and the passenger compartment provided that this barrier can
be released quickly by the driver in an emergency. A driver's door in a compartment
protected by such a barrier shall not be counted as an exit for passengers.

7.6.2.1.3. The provision of one or more additional service doors on the opposite side of the
vehicles in the case of vehicles designed for use in circumstances which require
loading/unloading on both sides. Examples of such circumstances include vehicles for
airside use at airports, vehicles for use on multimodal transport systems using island
platforms, or vehicles which cross borders to countries which do not drive on the same
side of the road as the country in which the vehicle is to be licensed for operation.
Vehicles so equipped shall be provided with control(s) which allow the driver to inhibit
normal operation of the doors which are not currently in use, or
7.6.2.1.4. The provision of a service door in the rear face of a Class A or B vehicle.
7.6.2.2. If the passenger's compartment has an area S equal or greater than 10 m , two of the
doors referred to in Paragraph 7.6.1.1 shall be separated such that the distance between
transverse vertical planes through their centres of area is not less than:
7.6.2.2.1. In the case of a single deck vehicle, 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).
If one of these two doors forms part of a double door this distance shall be measured
between the two doors which are furthest apart.
7.6.2.2.2. In the case of a double deck vehicle, two of the doors referred to in Paragraph 7.6.1.1
shall be separated such that the distance between transverse vertical planes through
their centres of area is not less than either 25% of the overall length of the vehicle or
40% of the overall length of the passenger compartment on the lower deck; this shall not
apply if the two doors are on different sides of the vehicle. If one of these two doors
forms part of a double door, this distance shall be measured between the two doors
which are furthest apart.
7.6.2.3. The exits (on each deck in the case of a double-deck vehicle) shall be placed in such a
way that their number on each of the two sides of the vehicle is substantially the same.
(This shall not imply the need to provide additional exits over and above the number
specified in Paragraph 7.6.1). Any exits in excess of the required minimum number need
not be substantially balanced on each of the two sides.
7.6.2.4. At least one exit shall be situated either in the rear face or in the front face of the vehicle
respectively. For Class I and A vehicles and for vehicles with a rear part permanently
closed off from the passenger compartment, this provision is fulfilled if an escape hatch
is fitted, or, if Paragraph 7.6.1.12 applies, an additional exit to those specified in
Paragraph 7.6.1, is fitted on each side of the vehicle. For double-deck vehicles, this
requirement shall apply only to the upper deck.
7.6.2.5. The exits on the same side of the vehicle shall be suitably spaced out along the length of
the vehicle.
7.6.2.6. A door shall, provided that it is not a service door, be permitted in the rear face of the
vehicle.
7.6.2.7. If escape hatches are fitted, they shall be positioned as follows: if there is only one hatch,
it shall be situated in the middle third of the passenger compartment, if there are two
hatches, they shall be separated by a distance of at least 2m measured between the
nearest edges of the apertures in a line parallel to the longitudinal axis of the vehicle.

7.6.4.6. If the direct view is not adequate, optical or other devices shall be installed to enable the
driver to detect from his seat the presence of a passenger in the immediate interior and
exterior vicinity of every side service door which is not an automatically-operated service
door.
In the case of double-deck vehicles of Class I, this requirement also applies to the
interior of all service doors and to the immediate vicinity of each intercommunication
staircase on the upper deck.
In the case of a service door in the rear face of the vehicle not exceeding 22 passengers,
this requirement is satisfied if the driver is able to detect the presence of a person 1.3m
tall standing 1m behind the vehicle.
Driving mirrors may be used to meet the requirements of this paragraph provided that
the field of view required for driving is still met.
In the case of doors situated behind the articulated section of an articulated vehicle,
mirrors shall not be deemed to be a sufficient optical device.
7.6.4.7. Every door which opens towards the interior of the vehicle and its mechanism shall be so
constructed that its movement is not likely to cause injury to passengers in normal
conditions of use. Where necessary, appropriate protection devices shall be fitted.
7.6.4.8. If a service door is located adjacent to a door to a toilet or other internal compartment the
service door shall be proofed against unintentional operation. However, this requirement
shall not apply if the door is locked automatically when the vehicle is moving at a speed
exceeding 5km/h.
7.6.4.9. In the case of vehicles having a capacity not exceeding 22 passengers, the service
doors of which are in the rear face of the vehicle, the leaves shall not be capable of
being opened more than 115° nor less than 85° and, when open, shall be capable of
being held automatically in that position. This does not preclude the ability to override
that stop and open the door beyond that angle when it is safe to do so; for example, to
enable reversing against a high platform for loading or to open the doors through 270° to
allow a clear loading area behind the vehicle.
7.6.4.10. The service door in any open position shall not obstruct the use of, or required access to,
any mandatory exit.
7.6.5. Additional Technical Requirements for Power-operated Service Doors
7.6.5.1. In the event of an emergency, every power-operated service door shall be capable,
when the vehicle is stationary or driving at a speed less than or equal to 5km/h, of being
opened from inside and, when not locked, from outside by controls which, whether or not
the power supply is operating:
7.6.5.1.1. Override all other door controls;
7.6.5.1.2. In the case of interior controls, are placed on, or within 300mm of, the door, at a height
(except in the case of interior controls for the door referred to in Annex 8,
Paragraph 3.9.1) of not less than 1,600mm above the first step;

7.6.5.6. The construction and control system of every power-operated service door shall be such
that a passenger is unlikely to be injured by the door or trapped in the door as it closes.
7.6.5.6.1. This requirement shall be considered satisfied if the following two requirements are met:
7.6.5.6.1.1. The first requirement is that when the closing of the door at any measuring point
described in Annex 6 is resisted by a clamping force not exceeding 150 N, the door shall
reopen automatically to its fullest extent and, except in the case of an
automatically-operated service door, remain open until a closing control is operated. The
clamping force may be measured by any method to the satisfaction of the competent
authority. Guidelines are given in Annex 6 to this Regulation. The peak force may be
higher than 150N for a short time provided that it does not exceed 300N. The reopening
system may be checked by means of a test bar having a section of height 60mm, width
30mm with corners radiused to 5mm.
7.6.5.6.1.2. The second requirement is that whenever the doors are closed onto the wrist or fingers
of a passenger:
7.6.5.6.1.2.1. The door reopens automatically to its fullest extent and, except in the case of an
automatically-operated service door, remains open until a closing control is operated, or
7.6.5.6.1.2.2. The wrist or fingers can be readily extracted from the doors without risk of injury to the
passenger. This requirement may be checked by hand, or by means of the test bar
mentioned in Paragraph 7.6.5.6.1.1, tapered at one end over a length of 300mm from a
thickness of 30mm to a thickness of 5mm. It shall not be treated with polish nor
lubricated. If the door traps the bar it shall be capable of being easily removed, or
7.6.5.6.1.2.3. The door is maintained at a position allowing the free passage of a test bar having a
section of height 60mm, width 20mm, with corners radiused to 5mm. This position shall
not be more than 30mm distant from the fully closed position.
7.6.5.6.2. In the case of a front service door the requirement of Paragraph 7.6.5.6 shall be
considered satisfied if the door:
7.6.5.6.2.1. Fulfils the requirements of Paragraphs 7.6.5.6.1.1 and 7.6.5.6.1.2, or
7.6.5.6.2.2. Is fitted with soft edges; these shall not, however be so soft that if the doors are closed
on the test bar mentioned in Paragraph 7.6.5.6.1.1 the rigid structure of the doors will
reach the fully closed position.
7.6.5.7. Where a power-operated service door is held closed only by the continued application of
the power supply there shall be provided a visual warning device to inform the driver of
any failure in the power supply to the doors.
7.6.5.8. A starting prevention device, if fitted, shall be effective only at speeds of less than 5km/h

service door is not fully closed. This audible warning shall be activated at a speed
exceeding 5km/h for doors complying with the requirements of Paragraph 7.6.5.6.1.2.3.

7.6.6.3.4. After deactivation of the opening controls of the automatically-operated service doors by
the driver, open doors shall close in accordance with Paragraphs 7.6.6.3.1 and 7.6.6.3.2.
7.6.6.4. Inhibition of the Automatic Closing Process on Doors Marked for Special Service, e.g. for
Passengers with Prams, Passengers with Reduced Mobility, etc.
7.6.6.4.1. The driver shall be able to inhibit the automatic closing process by actuation of a special
control. A passenger shall also be able to inhibit the automatic closing process directly
by pressing a special push-button.
7.6.6.4.2. The inhibition of the automatic closing process shall be indicated to the driver, e.g. by a
visual tell-tale.
7.6.6.4.3. Re-establishment of the automatic closing process shall in any case be capable of being
done by the driver.
7.6.6.4.4. Paragraph 7.6.6.3 shall apply to the subsequent closing of the door.
7.6.7. Technical Requirements for Emergency Doors
7.6.7.1. Emergency doors shall be capable of being easily opened from inside and from outside
when the vehicle is stationary. However, this requirement shall not be construed as
precluding the possibility of locking the door from the outside, provided that the door can
always be opened from the inside by the use of the normal opening mechanism.
7.6.7.2. Emergency doors, during their use as such, shall not be of the power-operated type
unless, once the controls prescribed in Paragraph 7.6.5.1 has been actuated and
returned to its normal position, the doors do not close again until the driver subsequently
operates a closing control. Activation of one of the controls in Paragraph 7.6.5.1 shall
cause the door to open to a width that the gauge as defined in Paragraph 7.7.2.1 can
pass through within a maximum of 8s after the operation of the control, or enable the
door to be easily opened by hand to a width that the gauge can pass through within a
maximum of 8s after the operation of the control. In addition emergency doors shall not
be of the sliding type except in the case of vehicles having a capacity not exceeding 22
passengers. For these vehicles a sliding door, which has been shown to be capable of
being opened without the use of tools after a frontal barrier collision test in accordance
with Regulation No. 33, can be accepted as an emergency door.
7.6.7.3. Every control or device for opening an emergency door (on the lower deck in the case of
a double deck vehicle) from the outside shall be between 1,000mm and 1,500mm from
the ground and not more than 500mm from the door. In vehicles of Classes I, II and III
every control or device for opening an emergency door from the inside shall be between
1,000mm and 1,500mm from the upper surface of the floor or step nearest to the control
and be not more than 500mm from the door. This shall not apply to controls located
within the driver's area.
Alternatively, the control referred to in Paragraph 7.6.7.2 for opening a power-operated
door may be placed according to Paragraph 7.6.5.1.2.

7.6.8.6. Every hinged emergency window which is not clearly visible from the driver's seat shall
be fitted with an audible warning device to warn the driver when it is not completely
closed. The window lock, and not the movement of the window itself, shall actuate this
device.
7.6.9. Technical Requirements for Escape Hatches
7.6.9.1. Every escape hatch shall operate so as not to obstruct the clear passage from inside or
outside the vehicle.
7.6.9.2. Roof escape hatches shall be ejectable, hinged or made of readily-breakable safety
glass. Floor hatches shall be either hinged or ejectable and shall be fitted with an audible
warning device to warn the driver when it is not securely closed. The floor escape hatch
lock, and not the movement of the hatch itself, shall actuate this device. Floor escape
hatches shall be proofed against unintentional operation. However this requirement shall
not apply if the floor hatch is locked automatically when the vehicle is moving at a speed
exceeding 5km/h.
7.6.9.3. Ejectable types shall not become totally detached from the vehicle when operated such
that the hatch is not a danger to other road users. The operation of ejectable escape
hatches shall be such that inadvertent operation is effectively prevented. Floor ejectable
hatches shall eject only into the passenger compartment.
7.6.9.4. Hinged escape hatches shall hinge along the edge towards the front or rear of the
vehicle and shall hinge through an angle of at least 100°. Hinged floor escape hatches
shall hinge into the passenger compartment.
7.6.9.5. Escape hatches shall be capable of being easily opened or removed from the inside and
from the outside. However, this requirement shall not be construed as precluding the
possibility of locking the escape hatch for the purpose of securing the vehicle when
unattended, provided that the escape hatch can always be opened or removed from the
inside by the use of the normal opening or removal mechanism. In the case of a
readily-breakable hatch, a device shall be provided adjacent to the hatch, readily
available to persons inside the vehicle, to ensure that the hatch can be broken.
7.6.10. Technical Requirements for Retractable Steps
Retractable steps, if fitted shall comply with the following requirements:
7.6.10.1. The operation of retractable steps may be synchronised with that of the corresponding
service or emergency door;
7.6.10.2. When the door is closed no part of the retractable step shall project more than 10mm
