   1.                                     NAME OF STANDARD
      1.                               This Standard is the Vehicle Standard (Australian Design Rule 43/02 – Vehicle Configuration and Dimensions) 2006.
      2.                               This Standard may also be cited as Australian Design Rule 43/02 — Vehicle Configuration and Dimensions.

Purpose and SCOPE

This Australian Design Rule (ADR) is part of the Australian motor vehicle standards 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 vehicle configuration and dimensions.

APPLICABILITY

This ADR applies to the design and construction of vehicles as set out in the table hereunder.

The  /02 Rule differs from the /01 Rule in that:

(1)   the marking requirements have been transferred to a new ADR, 61/00 "Vehicle Marking";

(2)  requirements for a ‘Semi-trailer’ with a sliding ‘Axle Group’ have been added.; and

(3)  a Clause 43.4.0 has been added which permits ‘Approved’ variations to dimensions.

The Package 13 issue of /02 relaxes the ‘Load Sharing Suspension’ requirements (Section 43.7) and alters the maximum dimensions of ‘Semi-trailers’ (Section 43.4.1.2)

Vehicles certified to any of the "Acceptable Prior Rules" as shown below in the Applicability Table for a particular vehicle category shall be deemed to comply with this Rule ** provided that “T-group" vehicles meet Clause 43.6.2.1.

Prior to the relevant date of effect, vehicles certified to ADR 43/02 must also be certified to ADR 61/00 "Vehicle Marking".
