1. SCOPE
1.1. This Regulation applies to vehicles of Categories N , N , O and O .
2. DEFINITIONS
2.1. For the purposes of this Regulation:
2.1.1. "Close-coupling device (CCD)" means a device which automatically provides sufficient
space between the bodies of towing vehicles and trailers if additional clearance is needed
during angular movement between them. Coupling devices having no adjusting effect on
lengths and/or angles within the device are not covered by this Regulation;
2.1.2. "Approval of a device" means the approval of a type of close-coupling device conforming
to the requirements set out in Section I below;
2.1.3. "Approval of a vehicle" means the approval of a vehicle with regard to the fitting of an
approved close-coupling device;
2.1.4. "Vehicle type" means vehicles which do not differ in such essential respects as:
2.1.4.1. The make and type of the close-coupling device;
2.1.4.2. The length and width of the vehicles;
2.1.4.3. The mass of the vehicles;
2.1.4.4. The points of attachment of the close-coupling device;
2.1.4.5. The vehicle description (e.g. truck, tractor, trailer, semi-trailer, centre-axle trailer);
2.1.4.6. Steering equipment (e.g. auxiliary steering equipment, steering equipment of the trailer).
2.1.5. "Type of close-coupling device" means devices which do not differ in such essential
respects as:
2.1.5.1. The make and type of the device;
2.1.5.2. The operating principle;
2.1.5.3. The means of attachment to vehicles;
2.1.5.4. The overall dimensions at minimum and maximum extension;
2.1.5.5. The limits of the operating angles;
2.1.5.6. The kinematic characteristics in relation to the angles of articulation;
2.1.6. "Automatic coupling procedure"
A coupling procedure is automatic if reversing the towing vehicle against the trailer is
sufficient to engage the coupling completely and properly and to secure it automatically and
to indicate proper engagement of the safety devices without any external intervention.

4.5. There shall be securely affixed to every CCD conforming to a vehicle type approved under
this Regulation, conspicuously and in a readily accessible place specified on the approval
form, an international approval mark consisting of:
4.5.1. A circle surrounding the letter "E" followed by the distinguishing number of the country which
has granted approval;
4.5.2. The number of this Regulation, followed by the letter "R", a dash and the approval number
to the right of the circle prescribed in Paragraph 4.5.1.
4.6. The approval mark shall be clearly legible and shall be indelible.
4.7. Annex 3 to this Regulation gives examples of arrangements of approval marks.
5. SPECIFICATIONS
5.1. General
5.1.1. The CCD shall be so designed, constructed and assembled such that a vehicle fitted with
the CCD conforms to the requirements of this Regulation under normal conditions of road
use. The coupling devices themselves must comply with the technical requirements of
Regulation No. 55. Additional forces which may be caused by the assembled CCD in
operation shall be taken into account.
5.1.2. The operation of the CCD shall be automatic. Even the reverse movement of the
close-coupled combination must be possible without any manual action at the CCD.
5.1.3.
In particular, the CCD shall be so designed, constructed and assembled so as to be
resistant to all stresses, corrosion and ageing to which it may be subjected (e.g. vibration,
humidity, extreme temperatures).
5.1.4. The CCD shall enable vehicles to travel in a straight line on a level road, without any
abnormal effort being applied to the steering control, either forwards or in reverse.
5.1.5. System Failures
5.1.5.1. Any power system failure and/or control system failure of the CCD, while the vehicle is
running, shall cause the coupling to extend and remain in that position. Separation of the
towing vehicle and trailer must be prevented by mechanical means under all conditions of
use.
5.1.5.2. Any power system and/or control system failure must be indicated to the driver by an
acoustic and an optical signal.

5.1.13. For hydraulic or pneumatic CCD's, an optical signal shall indicate that the CCD is about to
reach its maximum extension. This signal may be the same as the optical signal mentioned
in Paragraph 5.1.5.2.
5.1.14. The CCD shall be designed such that when coupling at an angle between the towing vehicle
and trailer different from that when uncoupled, unintentional movement of the trailer or
incorrect functioning of the CCD does not occur.
5.1.15. A plate specifying the maximum mass of the towing vehicle and the trailer, all lubrication
points and the frequency of lubrication shall be affixed such that it is clearly visible even
when the trailer is coupled.
5.2. Tests
The tests which the CCD shall undergo for approval are described in Annex 4 to this
Regulation.
6. MODIFICATION OF CCD TYPE AND EXTENSION OF APPROVAL
6.1. Any modification of the CCD type shall be notified to the administrative department which
approved the CCD type. The department may then either;
6.1.1. Consider that the modifications made are unlikely to have an appreciable adverse effect and
that the device still complies with the requirements; or
6.1.2. Require a further test report from the technical service responsible for conducting the tests.
6.2. Confirmation or refusal of approval, specifying the alteration, shall be communicated by the
procedure specified in Paragraph 4.3. above to the Contracting Parties applying this
Regulation.
6.3. The competent Authority issuing an extension of approval shall assign a series number for
such an extension and inform thereof the other Parties to the 1958 Agreement applying this
Regulation by means of a communication form conforming to the model in Annex 1 to this
Regulation.
7. CONFORMITY OF PRODUCTION
7.1. Every CCD approved under this Regulation shall be manufactured so as to conform to the
type approved by meeting the requirements set out in Paragraph 5. above.
7.2. In order to verify that the requirements of Paragraph 7.1. are met, suitable controls of the
production shall be carried out.
7.3. The holder of the approval shall, in particular:
7.3.1. Ensure the existence of procedures for effective control of the quality of products;
7.3.2. Have access to the control equipment necessary for checking the conformity to each
approved type;
7.3.3. Ensure that data of the test results are recorded and that related documents shall remain
available for a period to be determined in accordance with the administrative service;

10. NAMES AND ADDRESSES OF TECHNICAL SERVICES RESPONSIBLE FOR
CONDUCTING APPROVAL TESTS AND OF ADMINISTRATIVE DEPARTMENTS
10.1. The Parties to the Agreement applying this Regulation shall communicate to the United
Nations Secretariat the names and addresses of the technical services responsible for
conducting approval tests and of the administrative departments which grant approval and
to which forms certifying approval or extension, or refusal or withdrawal of approval or
production definitely discontinued, issued in other countries, are to be sent.
SECTION II
APPROVAL OF VEHICLES WITH REGARD TO THE FITTING OF AN APPROVED TYPE OF CCD
11. APPLICATION FOR APPROVAL
11.1. The application for approval of a vehicle type with regard to the fitting of a CCD of an
approved type shall be submitted by the vehicle Manufacturer or by his duly accredited
Representative.
11.2. It shall be accompanied by the undermentioned documents in triplicate and the following
particulars:
11.3. A detailed description of the vehicle type and the vehicle parts connected to the CCD,
including a dimensioned drawing of the fixing points and the information and documents
referred to in Annex 2.
11.4. At the request of the competent Authority, the approval form (i.e. the form indicated in
Annex 1 to this Regulation) for each type of CCD shall also be supplied.
11.5. A vehicle, representative of the vehicle type to be approved, fitted with a CCD, shall be
submitted to the technical service conducting the approval test.
11.5.1. A vehicle not having all the components appropriate to the type may be accepted provided
that the applicant can show to the satisfaction of the competent Authority that the absence
of the components omitted has no effect on the results of the inspections as far as the
requirements of this Regulation are concerned.
11.6. The competent Authority shall verify the existence of satisfactory arrangements for ensuring
effective control of the conformity of production before type approval is granted.
11.7. Special operating instructions shall be provided for coupling operations deviating from usual
ones, which must contain in particular, instructions regarding coupling and uncoupling with
different modes of operation (e.g. angled positions). Each vehicle must be accompanied by
such special operating instructions.

13. REQUIREMENTS CONCERNING THE FITTING OF AN APPROVED CCD
13.1. The requirements of Section I, Paragraph 5.1., excluding Paragraph 5.1.12. have to be
fulfilled when the CCD is fitted to the vehicle, despite any influences which may be caused
by the operation of the vehicle.
13.2. The CCD in use shall not impede the movement of the vehicles to which it is fitted. This
condition shall be deemed to have been met if the test requirements described in Annex 4
are complied with.
13.3. Warning signal as mentioned in Section I, Paragraphs 5.1.5.2. and 5.1.13.
13.3.1. The acoustic device must be located in the driver's cabin and must be easily audible by the
driver under all circumstances, when the vehicle is in normal use.
13.3.2. The optical signal shall be red in colour and located on the instrument panel in the direct

13.4. Coupling and uncoupling must be possible with coupling angles of up to 50° horizontally
both to the right and left, up to 10° vertically both upward and downward with full trailers, up
to 6° vertically both upward and downward with centre axle trailers and up to 7° when
twisted axially in both directions, i.e., it must be possible to couple the trailer up to the
above-mentioned angular positions between towing vehicle and trailer drawbars without the
necessity of intervention of additional personnel.
During automatic coupling it is permitted for a temporary position to be arranged before final
coupling is effected. The temporary position must permit the combination to be safely
manoeuvred. If the final action is operated manually the space between the vehicles must
be at least 500 mm.
13.5. It must be possible from the standing position for one person to position the coupling
devices prior to the coupling procedure without the use of tools. This requirement also
applies to the connection and disconnection of the braking and electrical lines.
13.6. General Requirements
To allow automatic coupling, the drawbar eye must be adjustable vertically to the centre
height of the coupling device under all usual traffic and operational conditions.
14. MODIFICATIONS OF THE VEHICLE TYPE AND EXTENSION OF APPROVAL
14.1. Any modification of the vehicle type as defined in Paragraph 2.1.4. shall be notified to the
administrative department which approved the vehicle type. The department may then
either:

ANNEX 4
REQUIREMENTS CONCERNING TESTS AND PERFORMANCE
(See Paragraph 5.1.10.)
1. CCD RECOVERY DISTANCE
1.1. The towing vehicle/trailer combination shall be driven, from a straight ahead position,
around a bend having an outside radius of 12.5 metres and stopped when the towing
vehicle has turned through an angle of 90° (yaw-angle). The combination shall then be
accelerated as quickly as possible up to a speed of 30 ± 2 km/h and be maintained at this
speed until completion of the test. Full retraction of the CCD must have taken place within
150 metres from the acceleration start position (see Figure 1 below).
This test shall be conducted in both left and right directions.
Note:
Compliance with these requirements does not guarantee that the overall length of the
vehicle combination is legal in all driving conditions.
Figure 1
1.2. The technical service shall verify that some retraction of the CCD takes place all the time
the towing vehicle is moving forward.

2.2.3. Starting from rest, a forward acceleration of at least 2 m/s shall not cause any movement
between the vehicles of a degree likely to cause the driver difficulty in controlling the vehicle
combination. (If the acceleration prescribed for this test cannot be reached by a vehicle
combination, the test shall be performed with the maximum acceleration available).
2.2.4. No permanent deformation shall take place during the above tests.
2.3. Change of lane
2.3.1. A simulated overtaking manoeuvre, as defined in the Appendix, conducted at a
progressively increasing speed up to 80 km/h, shall not cause the driver any difficulty in
controlling the combination.
2.3.2. At a speed of 20 km/h steering from one side of the track to the other alternately at least
3 times by turning the steering wheel as fast and as far as possible, no contact between the
vehicles or damage to the CCD shall occur (track width is 10 metres).
3. CIRCULAR MOVEMENT
3.1. Starting from rest and a straight ahead position, the combination shall be driven around a
curve of 25 m radius to a speed of 20 km/h at an acceleration of 2 ± 10% m/s . This shall
not cause any movement between the vehicles of a degree likely to cause the driver
difficulty in controlling the vehicle combination.
3.2. With the towing vehicle and trailer having adopted a steady state, turn so that the front
outside edge of the towing vehicle describes a circle of radius of 25 m, at a constant speed
of 5 km/h. The circle described by the rearmost outer edge of the trailer shall be measured.
This manoeuvre shall be repeated under the same conditions but at a speed of 25 km/h ± 1
km/h.
During these manoeuvres, the rearmost outer edge of the trailer, travelling at a speed of 25 km/h
± 1 km/h, shall not move outside the circle described during the manoeuvre at a constant speed
of 5 km/h by more than 0.70 m (see Figure 2 below).
Figure 2

3.4. Any motor vehicle or combined vehicle which is in motion must be able to turn within a
swept circle having an outer radius of 12.50 m and an inner radius of 5.30 m. The test shall
be conducted in both left and right directions. No part of the combination, where it
penetrates the circle from a tangent, may overlap that tangent by more than 0.8 m beyond
the point of intersection (see Figure 4 below).
