GLOBAL TECHNICAL REGULATION NO. 12
I. STATEMENT OF TECHNICAL RATIONALE AND JUSTIFICATION
A. INTRODUCTION
1. It is important to note that many vehicle collisions result from driver distraction. One
identifiable source of such distraction is diversion of the driver’s attention from the
driving task. This can be caused by confusing information displayed in the drivers' field
of vision and unclear identification, location and, or operation of the controls necessary
for vehicle operation.
2. The objective of the global technical regulation (gtr) is to reduce the safety hazards
caused by rider distraction. Specifically, the proposal is intended to reduce distractions
resulting from an error in control selection or inconsistency in graphical representations
of tell-tales and indicators from one motorcycle to another.
3. When people purchase new vehicles in countries allowing motorcycles certified in
different jurisdictions, they are faced with different tell-tales and means of identifying
controls. Drivers need time to learn their dashboard messages and to identify their
vehicle controls. During this time such drivers have to divide their attention between the
increasingly difficult task of driving, the identification of controls and the comprehension
of tell-tales provided to "ease" the driving task.
4. One of the main purposes of this gtr is to standardize and harmonize markings
identifying controls, tell-tales and indicators. One way of doing this is through the use of
symbols. A clear advantage of symbols, or pictograms, over wording is that symbols,
once they have been taught to and have been recognised by the target group,
overcome language barriers. Drivers shall be able to operate motorcycles safely, even
if they cannot understand the language of the country they are visiting. Recognition that
is independent of language is an advantage in a global motorcycle market.
5. Furthermore, some Contracting Parties have more than one official language and
require that motorcycle safety information be presented in all official languages. This
could result in a requirement to provide a language selection function to drivers or a
means to display wording in all official languages, which would be difficult on spacelimited
dash panels.
6. This gtr is developed to harmonize the way in which motorcycle controls, tell-tales and
indicators are installed and identified.
7. This gtr applies to all on-road motorcycles. It specifies requirements for the location,
identification, operation, colour, and illumination of motorcycle tell-tales, indicators and
controls. It also harmonizes a set of symbols for, if fitted, controls, tell-tales and
indicators.
8. This gtr ensures the accessibility, visibility, and recognition of motorcycle controls,
tell-tales, and indicators and facilitates the proper selection of controls under daylight
and night-time conditions. The gtr also aims at reducing the safety hazards caused by
the diversion of the rider's attention from the driving task by mistakes in selecting
controls.

17. Symbols are one of the efficient ways of communicating information to drivers. The
consistent use of a selected symbol in all new motorcycles will increase its recognition.
Symbols have the potential to simplify motorcycle design and, once taught and
recognised, to reduce driver confusion.
18. This gtr attempts to reduce the variety by covering the requirements of as many
controls as possible. This does not imply that all those controls and their requirements
included in this gtr are mandatory. Each Contracting Party still decides the mandatory
controls and the related requirements such as e.g., presence of tell-tales in their region
through specific legislation.
C. BACKGROUND TO GTR
19. The proposal to establish this gtr was adopted by the Executive Committee (AC.3) of
the 1998 Global Agreement at its twenty-fifth session, in March 2009. It is described in
document ECE/TRANS/WP.29/AC.3/22 (appended to this gtr in conformity with
Paragraph 6.2.7. of the Agreement).
20. Italy agreed to sponsor the proposal for the gtr and in 2008. The International
Motorcycle Manufacturers Association (IMMA) undertook to review the similarity
between the symbols used for cars and motorcycles, the recognition of symbols and
market practice.
21. The results of the IMMA study of how the symbols were being used were presented to
the ninety-fifth session of GRSG and to the 139th session of WP29. The study stated
that the symbols listed by IMMA were used worldwide. This justified them being used in
the gtr whereas those which were frequently found in some regions only could be
considered for future amendments of the gtr.
22. The study also concluded that several Contracting Parties allowed the use of language
as an alternative means of marking controls and this practice should not be affected by
the adoption of the gtr by such administrations.
23. The first full discussion, based on the comparison document drafted by IMMA was held
at the ninety-seventh session of GRSG.
24. At its ninety-seventh session, GRSG proposed the formation of an informal group on
motorcycle controls, tell-tales and indicators (MCSYM) under the chairmanship of Italy
and with secretarial support from IMMA. The meetings were open to all interested
parties. The participants in the informal groups included representatives of Canada,
India, Japan, Korea, USA, the European Commission and IMMA.

E. REGULATORY IMPACT AND ECONOMIC EFFECTIVENESS
31. Although this gtr does not quantify any measurable threat to motorcycle safety, GRSG
has agreed that there is a need to harmonize identification, operation and location of
motorcycle controls, tell-tales and indicators.
32. Driver distraction significantly contributes to incidents involving motorcycles.
Standardizing controls, tell-tales and indicators could reduce driver distraction, resulting
in improved safety for all road-users.
33. Since all the symbols prescribed in the gtr are currently accepted by most of the
Contracting Parties, the cost is minimal. The gtr ensures better understanding of safety
symbols by riders around the world.
34. Defining the location, operation and identification of controls and displays is of sufficient
importance to warrant this gtr. This gtr is a first step. As other controls, tell-tales and
indicators get used and get recognition these will be considered to be added to the
current list through revisions and addendums to the gtr.
F. PURPOSE OF AMENDMENT 1
35. At its June 2012 session, the Executive Committee (AC.3) of the 1998 Global
Agreement noted the proposal by the representative of Italy for an amendment to
global technical regulation (gtr) No. 12 aimed at clarifying the provisions on the
location, identification and operation of motorcycle controls, tell-tales and indicators. At
its November 2012 session, AC.3 gave its consent for the proposal to develop the
amendment (ECE/TRANS/WP.29/2012/123).
36. At its 102nd, the Working Party on General Safety Provisions (GRSG) noted an
informal proposal amending the gtr (see report ECE/TRANS/WP.29/GRSG/82) and
adopted the proposal at its 103rd session of GRSG on the basis of official document
ECE/TRANS/WP.29/GRSG/2012/21. The document would be submitted to AC.3 for
consideration at its March 2013 session.

3.8. "Handlebars: forward" means any part of the handlebars lying on the side furthest
from the driver when seated in a driving position.
3.9. "Handgrip" means that part of the handlebars, furthest from the centre, by which the
handlebars are held by the driver of the vehicle.
3.10. "Rotating handgrip" means a handgrip, operating some functional mechanism of the
vehicle, which is free to rotate around the handlebar when so turned by the driver of the
vehicle.
3.11. "Frame" means any part of the frame, chassis or cradle of the vehicle, to which is
attached the engine and/or transmission unit, and/or the engine and transmission unit

forward movement, lies on the left side of the longitudinal median plane of the vehicle
3.13. "Frame: right side": means any part of the frame which, when facing the direction of
forward movement, lies on the right side of the longitudinal median plane of the vehicle
3.14. "Lever" means any device consisting of an arm turning on a fulcrum, by means of
which some functional mechanism of the vehicle is operated.
3.15. "Hand lever" means a lever operated by the hand of the driver;
Note. Unless otherwise stated, a hand lever is operated by compression, (that is,
movement of the apex of the lever towards the supporting structure), e.g. to engage a
brake mechanism or to disengage the clutch mechanism.
3.16. "Foot lever" means a lever operated by contact between the foot of the driver and a
spur projecting from the arm of the lever.
3.17. "Pedal" means a lever operated by contact between the foot of the driver and a pad on
the lever, so placed as to allow pressure to be applied to the arm of the lever.
Note. Unless otherwise stated, a pedal is operated by depression, for example to
engage a brake mechanism.
3.18. "Rocker arm" means a lever, pivoted at or near its centre and having a pad or spur at
each end, operated by contact between the foot of the driver and the said pads or
spurs.
3.19. "Clockwise" means the direction of rotation around the axis of the part considered,
following the motion of the hands of a clock when viewed from the upper or the outer
side of the part considered.
3.20. "Anticlockwise" has the inverse meaning of "clockwise";

4.2.5. Paragraph 4.2.3. does not apply to multi-function controls, if the control is associated
with a multi-task display that:
4.2.5.1. Is visible to the driver; and
4.2.5.2. Identifies the control with which it is associated; and
4.2.5.3. Identifies all of the vehicle systems for which control is possible from the multi-function

technical regulation.
4.3.4. If the control, indicator or tell-tale for the same function are combined, one symbol may
be used to identify that combination.
4.3.5. All identification symbols for the tell-tales, indicators and controls provided on handle
bar or instrument cluster shall be positioned so as to appear to the driver to be
perceptually upright except for an audible warning device control. For rotating controls
that have an "off" position, this requirement applies to the control in the "off" position.
