3. APPLICATION FOR APPROVAL
3.1. The application for approval of a vehicle type with regard to a protective device to prevent its
unauthorised use shall be submitted by the manufacturer or by his duly accredited
representative.
3.2. It shall be accompanied by the under-mentioned documents in triplicate and by the following
particulars:
3.2.1. A detailed description of the vehicle type with regard to the arrangement and design of the
control or of the unit on which the protective device acts;.
3.2.2. Drawings, on an appropriate scale and in sufficient detail, of the protective device and of its
mountings on the vehicle;
3.2.3. A technical description of the device.
3.3. There shall be submitted to the technical service responsible for conducting the approval
tests:
3.3.1. A vehicle representative of the vehicle type to be approved if requested by the technical
service; and also
3.3.2. At the request of the technical service, such components of the vehicle as the service
deems essential for the checks prescribed in Paragraphs 5 and 6 of this Regulation.
4. APPROVAL
4.1. If the vehicle type submitted for approval pursuant to the Regulation meets the requirements
of Paragraphs 5, and 6 below, approval of that vehicle type shall be granted.
4.2. An approval number shall be assigned to each type approved. The first two digits (at
present 03, corresponding to the 03 series of amendments which entered into force on
June 23, 2005) shall indicate the series of amendments incorporating the most recent major
technical amendments made to the Regulation at the time of issue of the approval. The
same Contracting Party may not assign the same number either to the same vehicle type
equipped with another type of protective device or whose protection device is mounted
differently, or to another vehicle type.
4.3. Notice of approval or of refusal of approval of a vehicle type pursuant to this Regulation
shall be communicated to the Contracting Parties to the Agreement which apply this
Regulation by means of a form conforming to the model in Annex 1 to this Regulation and of
drawings of the protective device and its mounting supplied by the applicant for approval, in
a format not exceeding A4 (210 × 297mm) or folded to that format and on an appropriate
scale.

5.4. The protective device referred to in Paragraph 5.1. above, and the vehicle components on
which it operates, shall be so designed that it cannot rapidly and without attracting attention
be opened, rendered ineffective, or destroyed by, for example, the use of low-cost, easily
concealed tools, equipment or fabrications readily available to the public at large.
5.5. The protective device shall be mounted on the vehicle as an item of original equipment
(i.e. equipment installed by the vehicle manufacturer prior to first retail sale). It shall be fitted
in such a way that even after removal of its housing it cannot, when in the blocked condition,
be dismantled otherwise than with special tools. If it would be possible to render the
protective device ineffective by the removal of screws, the screws shall, unless they are
non-removable screws, be covered by parts of the blocked protective device.
5.6. The key locking system shall provide at least 1,000 different key combinations or a number
equal to the total number of vehicles manufactured annually if less than 1,000. In vehicles of
one type the frequency of occurrence of each combination shall be roughly one per 1,000.
5.7. The key and lock shall not be visibly coded.
5.8. The lock shall be so designed, constructed and fitted that turning of the lock cylinder, when
in the locked position, with a torque of less than 2.45Nm is not possible with anything other
than the mating key, and
5.8.1. For lock cylinders with pin tumblers no more than two identical tumblers operating in the
same direction shall be positioned adjacent to each other, and in a lock there shall not be
more than 60% identical tumblers.
5.8.2. For lock cylinders with disc tumblers no more than two identical tumblers operating in the
same direction shall be positioned adjacent to each other, and in a lock there shall not be
more than 50% identical tumblers.
5.9. Protective devices shall be such as to exclude any risk while the vehicle is in motion, of
accidental blockage likely to compromise safety in particular.
5.9.1. It shall not be possible to activate devices to prevent unauthorised use without first setting
the engine controls to a stop condition and then performing an action which is not an
uninterrupted continuation of stopping the engine, or without first setting the engine controls
to a stop condition when the vehicle is stationary with the parking brake applied, or the
speed of the vehicle does not exceed 4 km/h.
5.9.2. In the case of devices acting on the steering, transmission, gear shift control or brakes, if the
action of key withdrawal activates the device, it shall either necessitate a minimum
movement of 2mm before activation of the device or incorporate an override facility to
prevent accidental removal or partial withdrawal of the key.
5.9.3. Paragraphs 5.8, 5.8.1 or 5.8.2, and 5.9.2 are only applicable to devices which include
mechanical keys.
5.10. Power assistance may be used only to activate the locking and/or unlocking action of the
protective device. The device shall be kept in its operating position by mechanical means
only.
5.11. It shall not be possible to activate the motive power of the vehicle by normal means until the
protective device has been deactivated.

6.2.6. If the protective device is such that the key can be removed in a position other than the
position in which the transmission is or the brakes are locked, it shall be so designed that
the manoeuvre required to reach that position and remove the key cannot be effected
inadvertently.
6.2.7. In the case when a protective device acting on the transmission is used, it shall be strong
enough to withstand, without damage likely to compromise safety, the application in both
directions and in static conditions of a torque 50% greater than the maximum torque that
can normally be applied to the transmission. In determining the level of this testing torque
account shall be taken, not of the maximum engine torque, but of the maximum torque that
can be transmitted by the clutch or by the automatic transmission.
6.2.8. In the case of a vehicle equipped with a protective device acting on brakes, the device must
be capable of holding the laden vehicle stationary on an 18% up or down-gradient.
6.2.9. In the case of a vehicle equipped with a protective device acting on brakes, the
requirements of this Regulation shall not be construed as a departure from the requirements
of Regulation 13 or 13-H even in the case of a failure.
6.3. Protective Devices Acting on the Gearshift Control
6.3.1. A protective device acting on the gearshift control shall be capable of preventing any
change of gear.
6.3.2. In the case of manual gearboxes it must be possible to lock the gearshift lever in reverse
only; in addition locking in neutral shall be permitted.
6.3.3. In the case of automatic gearboxes provided with a "parking" position it must be possible to
lock the mechanism in the parking position only; in addition locking in neutral and/or reverse
shall be permitted.
6.3.4. In the case of automatic gearboxes not provided with a "parking" position it must be possible
to lock the mechanism in the following positions only; neutral and/or reverse.
6.3.5. The protective device shall be so designed and constructed that it remains fully effective
even after some degree of wear as a result of 2,500 locking cycles in each direction.
7. MODIFICATION OF THE VEHICLE TYPE AND EXTENSION OF APPROVAL
7.1. Every modification of the vehicle type shall be notified to the administrative department
which approved the vehicle type.
The department may then either:
7.1.1. Consider that the modifications made are unlikely to have an appreciable adverse effect and
that in any case the protective devices still comply with the requirements, or
7.1.2. Require a further report from the technical service responsible for conducting the tests.
7.2. Confirmation or refusal of approval, specifying the alteration shall be communicated by the
procedure specified in Paragraph 4.3. above to the Contracting Parties to the Agreement
applying this Regulation.
7.3. The competent authority issuing the extension of approval shall assign a serial number to

11.2.2.2.2. Type of Optical Signal
Flashing of all direction indicators and/or passenger compartment light of the vehicle,
including all lamps in the same electrical circuit.
