Communication Concerning the Approval or Extension or Refusal or Withdrawal of
Approval or Production Definitely Discontinued of a Vehicle Type with Regard to the
Speedometer Equipment Including its Installation Pursuant to Regulation No. 39
Annex 2 – Arrangements of Approval Marks
Annex 3 – Test of Speedometer Accuracy for Conformity of Production

2.5. "speedometer" means that part of the speedometer equipment which indicates to the
driver the speed of his vehicle at any given moment;
2.5.1. "tolerances of the speedometers measuring mechanism" shall mean the accuracy of
the speedometer instrument itself, expressed as the upper and the lower speed indication
limits for a range of speed inputs;
2.5.2. "technical constant of the speedometer" shall mean the relationship between the input
revolutions or pulses per minute and a specified displayed speed.
2.6. "odometer" means that part of the odometer equipment which indicates to the driver the
total distance recorded by the vehicle since its entry into service.
2.6.1. "Technical constant of the odometer" means the relationship between the input
revolutions or pulses and the distance travelled by the vehicle.
2.7. "unladen vehicle" means the vehicle in running order, complete with fuel, coolant,
lubricant, tools and a spare wheel (if provided as standard equipment by the vehicle
manufacturer), carrying a driver weighing 75kg, but no driver's mate, optional accessories or
load.
3. APPLICATION FOR APPROVAL
3.1. The application for approval of a vehicle type with regard to the speedometer and odometer
equipment including its installation shall be submitted by the vehicle manufacturer or by his
duly accredited representative.
3.2. It shall be accompanied by the following documents in triplicate and by the following
particulars:
3.2.1. A description of the vehicle type with regard to the items mentioned in Paragraphs 2.2., 2.3.,
2.4., 2.5., and 2.6. above; the vehicle type shall be specified.
3.3. An unladen vehicle representative of the vehicle type to be approved shall be submitted to
the technical service conducting approval tests.
3.4. The competent authority shall verify the existence of satisfactory arrangements for ensuring
effective control of the conformity of production before type-approval is granted.

5. SPECIFICATIONS
5.1. An onboard speedometer and odometer complying with the requirements of this Regulation
shall be fitted to the vehicle to be approved.
5.2. The display of the speedometer shall be located within the direct field of view of the driver
and shall be clearly legible both day and night. The range of speeds displayed shall be
sufficiently wide to include the maximum speed of this type of vehicle as stated by the
manufacturer.
5.2.1. In the case of speedometers intended for vehicles of Categories M, N, and L , L L , and L
the graduation shall be 1, 2, 5 or 10km/h. The numerical values of the speed shall be
indicated on the display as follows: when the highest value on the display does not exceed
200km/h, speed values shall be indicated at intervals not exceeding 20km/h. When the
maximum value on the display exceeds 200km/h, then the speed values shall be indicated
at intervals not exceeding 30km/h. The indicated numerical speed value intervals need not
be uniform.
If a setting makes it possible for the driver to choose between the speed in km/h and mph
(miles per hour), then the speed may be displayed only in either km/h or mph at any one
time. The corresponding unit shall permanently be displayed.
5.2.2. In the case of vehicles of Categories M, N, and L , L , L , and L manufactured for sale in
any country where imperial units are used, the speedometer shall also be marked in miles
per hour (mph); the graduations shall be of 1, 2, 5 or 10mph.
The speed may be displayed either in km/h or mph at any one time provided that a setting
makes it possible for the driver to choose between the speed in km/h and mph, in that case
the corresponding unit shall permanently be displayed.
The numerical values of the speed shall be indicated on the display at intervals not
exceeding 20mph and commencing at 10 or 20mph. The indicated numerical speed value
intervals need not be uniform.
5.2.3. In the case of speedometers intended for vehicles of Categories L (mopeds), L , and L ,
the display readings must not exceed 80km/h. The graduation shall be 1, 2, 5 or 10km/h and
the marked numerical values of the speed indicated shall not exceed 10km/h. The indicated
numerical speed value intervals need not be uniform.
5.2.4. In the case of vehicles of categories L , L and L manufactured for sale in any country
where imperial units are used, the speedometer shall also be marked in mph; the graduation
shall be of 1, 2, 5 or 10mph. The numerical values of the speed shall be indicated on the
display at intervals not exceeding 10mph and starting at 10 or 20mph. The indicated
numerical speed value intervals need not be uniform. If a setting makes it possible for the
driver to choose between the speed in km/h and mph, then the speed may be displayed
only in km/h or mph at one time at any one time. The corresponding unit shall permanently
be displayed.
5.3. The accuracy of the speedometer equipment shall be tested in accordance with the
following procedure:
5.3.1. The tyres shall be one of the types normally fitted to the vehicle as defined in Paragraph 2.3.
of this Regulation. A test shall be carried out for each type of speedometer intended to be
fitted by the manufacturer.

6. MODIFICATIONS OF THE VEHICLE TYPE
6.1. Every modification of the vehicle type shall be communicated to the administrative
department which approved that vehicle type. The department may then either:
6.1.1. consider that the modifications made are unlikely to have an appreciable adverse effect and
that in any case the vehicle still meets the requirements; or
6.1.2. require a further report from the technical service responsible for conducting the tests.
6.2. Notice of confirmation or refusal of approval, accompanied by particulars of the
modifications, shall be communicated by the procedure specified in Paragraph 4.3. above to

7.2. Every vehicle approved under this Regulation shall be so manufactured as to conform to the
type approved by meeting the requirements of the relevant part(s) of this Regulation.
7.3. For each type of vehicle sufficient checks are carried out regarding the speedometer
equipment and its installation; in particular, for each type of vehicle at least the test
prescribed in Annex 3 to this Regulation shall be carried out.
7.4. The authority, which has granted type-approval, may at any time verify the conformity
control methods applied in each production facility. The normal frequency of these
verifications shall be once every two years.
7.5. Where unsatisfactory results are found during verifications and checks pursuant to
Paragraph 7.4 above, the competent authority shall ensure that all necessary steps are
taken to restore conformity of production as rapidly as possible.
8. PENALTIES FOR NON-CONFORMITY OF PRODUCTION
8.1. The approval granted for a vehicle type pursuant to this Regulation may be withdrawn if the
requirement laid down in Paragraph 7.1. above is not met or if the vehicles have failed to
