Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following
URL: www .iso .org/ iso/ foreword .html.
This document was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 39,
Ergonomics.
This third edition cancels and replaces the second edition (ISO 12214:2010), of which it constitutes a
minor revision. The changes compared to the previous edition are as follows:
— the first sentence of 4.3.5.2 has been deleted and the following added: “If the wiper and turn signal
are located on the same side of the steering wheel, the wiper shall only be turned on by rotating over
the top”;
— in 4.3.5.3, “or pushing” has been included, so that the text reads: “Pulling or pushing the left or right
stalk should be the motion for turning on the headlamp high beam.”

Introduction
Drivers develop expectations regarding the operating motions of various types of controls as a result of
their accumulated experience with vehicle controls. To simplify the operation of controls for drivers, the
direction-of-motion to operate these controls needs to conform to these expectations, or stereotypes.
The strength of a stereotype varies with the control configuration (control type, location, orientation
and mounting plane). Studies have demonstrated that stereotype strength is not related to driver age,
gender, or left- or right-handedness. Failure to conform to direction-of-motion stereotypes can lead to
actuation errors, longer operating times and an increase in driver workload.
This document is based on past research and general human factor principles. Control labelling and
tactile or shape coding are not addressed in this document. However, appropriate labelling and coding
can improve the accuracy of control use.

Road vehicles — Direction-of-motion stereotypes for
automotive hand controls
1 Scope
This document gives design recommendations and requirements for the direction-of-motion of hand
controls found in passenger, multipurpose and commercial vehicles, and buses.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— IEC Electropedia: available at http:// www .electropedia .org/
— ISO Online browsing platform: available at https:// www .iso .org/ obp
3.1
control configuration
particular combination of control type, location, orientation and mounting plane
3.2
direction-of-motion stereotype
direction of control motion expected by a majority of people to achieve a given effect for a specified
control configuration
3.3
stereotype strength
percentage of people who activate the control in a particular direction
3.4
on/increase control
control whose function is to turn something on/off or to increase/decrease some unspecified effect
3.5
specific function control
control used to activate some specific function or achieve a specific effect
EXAMPLE Control to lock or unlock doors, raise or lower windows, or turn on headlamps, headlamp high
beam or windshield wipers.
4 Design
4.1 General
This document gives the recommended direction-of-motion and control orientation for controls
mounted on each of three orthogonal planes:
