Purpose and SCOPE
This Australian Design Rule (ADR) is part of the Australian motor vehicle standard system and is a national standard for the purposes of the Motor Vehicle Standards Act 1989.
The function of this Australian Design Rule is to specify requirements for the provision and location of certain `Visual Indicators'. It also specifies requirements for speedometers and odometers.

18.1. DEFINITIONS
18.1.1. Refer to Vehicle Standard (Australian Design Rule Definitions and Vehicle Categories) 2005.
18.1.2. 'Visual Indicator' - that part of an instrument or device intended to display information for the driver and includes any specified label
18.1.3. 'Totally Visible' - means that the sum of the view from each of the 2 eyes includes all the ‘Visual Indicators'.
18.2. `VISUAL INDICATORS' FOR MA VEHICLES ONLY
18.2.1. The display of information presented by the following 'Visual Indicators', if fitted. shall be subject to control under this Rule:
Group I
(a) Speedometer
(b) Direction indicator "tell-tale" lamp or lamps
(c) High beam indicator
Group II
(d) Tachometer
(e) Odometer
(f) Service brake failure indicator lamp
(g) Parking brake indicator lamp
(h) Stop lamp failure indicator
(i) Oil temperature indictor
(j) Pressure indicator
(k) Water temperature indicator
(l) Battery charge failure indicator
(m) Fuel level indicator.
18.2.2. In cases where more than one 'Visual Indicator' are provided for any one of the functions covered by (h) to (m) above, and are not located as specified in Clause 18.3.2 a common indicator which could be either visual or an audible signal may be used to draw attention to the need to refer to a group of indicators located elsewhere.
18.2.2.1. In such cases the common indicator, if visual, shall be totally located within the area specified in Clause 18.3.2.
18.3. LOCATION OF 'VISUAL INDICATORS' FOR MA VEHICLES ONLY
18.3.1. All 'Visual Indicators' specified as Group I in Clause 18.2 shall be totally located between 2 vertical planes inclined at 20o left and 20o right of the longitudinal axis of the vehicle and passing through the foremost points of the left and right '95th Percentile Eye Ellipses' respectively. Such indicators shall be totally located above a plane inclined downwards at 35o from the horizontal and including a horizontal transverse line through the foremost points of each of the '95th Percentile Eye Ellipses' and below a plane tangential to the bottom of the '95th Percentile Eye Ellipses' which includes a line at ground level transverse to the longitudinal axis of the vehicle 11 m forward of the rearmost eye ellipse point.
18.3.2. All 'Visual Indicators' specified as Group II in Chase 18.2 shall be totally located between 2 vertical planes inclined at 40o' left and 25o right of the longitudinal axis of the vehicle and passing through the foremost points of the left and right '95th Percentile Eye Ellipses' respectively. Such indicators shall be totally located above a plane inclined downwards at 35o from the horizontal and including a horizontal transverse line through the foremost points of each of the '95th Percentile Eye Ellipses' and below a plane tangential to the bottom of the '95th Percentile Eye Ellipses' which includes a line at ground level, transverse to the longitudinal axis of the vehicle 11 m forward of the rearmost eye ellipse point'.
18.4. VISIBILITY OF 'VISUAL INDICATORS' FOR MA VEHICLES ONLY
18.4.1. The requirements of Clauses 18.4.1.1 and 18.4.1.2 shall be met when:
(a) the steering wheel is in the straight ahead position;
(b) the direction indicator lever is in the “Neutral” Position;
(c) in the case of column change automatic transmission vehicles the gear selector is in the “Drive" position;
(d) in the case of column change manual transmission vehicles with 2 or 3 forward gear ratios, the gear selector is in "Top” gear position;
(e) in the case of column change manual transmission vehicles with more than 3 forward gear ratios, the gear selector is in 'Top" gear position or the next lower gear position whichever is the more critical in terms of obscuration of 'Visual Indicators’'.
18.4.1.1. All 'Visual Indicators' other than indicator lamps shall be 'Totally visible' when viewed from each pair of eye positions located by the '95th Percentile Eye Ellipses' except that
18.4.1.1.1. in the case of Group I ‘Visual Indicators', the portion of the steering wheel rim including its supporting arms that is below a plane tangential to the top of the '95th Percentile Eye Ellipses' and the underside of the highest rim cross section cut normal to the rim, shall not constitute an obstruction;
18.4.1.1.2. in the case of Group II 'Visual Indicators' the steering wheel rim and its supporting arms and attachments thereto shall not constitute obstructions.
18.4.1.2. Any object which represents an obstruction to any single eye position within the terms of Clause 18.4.1.1 shall have no surfaces, in the line of sight to the ‘Visual Indicator', which present a metal finish with a 'Specular Gloss' exceeding 40 units when measured by the 20 degree geometry method of ASTM Standard D523 62T "Specular Gloss" June 1962 or ASTM Standard D523-85T-"Specular Gloss", September 1985.
18.4.1.3. All indicator lamp ‘Visual Indicators' shall either be 'Totally Visible', or an area of not less than 18 square millimetres with dimensions such that a 2 mm diameter circle is totally enclosed within the area, shall be 'Totally Visible’ when viewed from each single eye position located by the '95th Percentile Eye Ellipses'. The obstruction exemptions provided for in Clause 18.4.1.1 shall also be applicable to this Clause.
18.4.1.4. In the case of a motor vehicle provided with a steering wheel capable of axial and vertical adjustments, it shall be demonstrated that for any eye position located by the '95th Percentile Eye Ellipses', there is at least one steering wheel position where the requirements of Clauses 18.4.1.1 to 18.4.1.3 are complied with.
18.4.2. The vehicle speed indicating element shall be of such colour or contrast as to differentiate it from the viewed background.
18.4.3. All 'Visual Indicators’ other than indicator lamps shall be provided with variable intensity when illuminated.
Note: A switch which provides a means of varying the illumination to ‘Visual Indicators', but is not integral with the on/off control for the illumination of ‘Visual Indicators' is acceptable as a means of providing variable intensity illumination to 'Visual Indicators'. It shall be acceptable for the intensity control to have not less than 2 levels of adjustment other than an "off" position provided that each position results in a substantially different level of illumination to 'Visual Indicators'.
18.5. SPEEDOMETERS AND ODOMETERS (ALL VEHICLES)
18.5.1. Speedometers
18.5.1.1. Unless otherwise 'Approved', every vehicle shall be fitted with a speedometer which shall:
18.5.1.1.1. indicate vehicle speed only in kilometres per hour and
18.5.1.1.2. indicate the actual vehicle speed, for all speeds above 40 km/h, to an accuracy of ± 10 percent
18.5.1.2. The speedometer shall be installed so that its indication is readily visible to the driver when seated in the normal driving position.
18.5.2. Odometers
18.5.2.1. Every vehicle other than L-group vehicles shall be fitted with an odometer which shall:
18.5.2.1.1. indicate distance travelled in one kilometre units (or less) from 1 to 999,999 kilometres; and
18.5.2.1.2. indicate the actual distance travelled by the vehicle to an accuracy of ±4 per cent.
18.5.2.2. Every vehicle of category LC and LD shall be fitted with an odometer which shall:
18.5.2.2.1. indicate distance travelled in one kilometre units from I to 99,999 kilometres and
18.5.2.2.2. indicate the actual distance travelled by the vehicle to an accuracy of ± 4 percent
