NAME OF STANDARD 1.1.1. This Standard is the Vehicle Standard (Australian Design Rule 58/00 – Requirements for Omnibuses Designed for Hire and Reward) 2006. 1.1.2. This Standard may also be cited as Australian Design Rule 58/00 — Requirements for Omnibuses Designed for Hire and Reward. 1.2. COMMENCEMENT 1.2.1. This Standard commences on the day after it is registered. 1.3. REPEAL 1.3.1. This Standard repeals each vehicle standard with the name Australian Design Rule 58/00 — Requirements for Omnibuses Designed for Hire and Reward that is: (a) made under section 7 of the Motor Vehicles Standard Act 1989; and (b) in force at the commencement of this Standard. 1.3.2. This Standard also repeals each instrument made under section 7 of the Motor Vehicles Standard Act 1989 that creates a vehicle standard with the name Australian Design Rule 58/00 — Requirements for Omnibuses Designed for Hire and Reward, if there are no other vehicle standards created by that instrument, or amendments to vehicle standards made by that instrument, that are still in force at the commencement of this Standard. 2. Purpose and SCOPE The function of this Australian Design Rule is to specify requirements for the construction of omnibuses designed for, and intended for licensing for, hire and reward. They must also comply with all requirements for omnibuses as set out in individual ADRs. 3. APPLICABILITY AND IMPLEMENTATION This ADR applies to the design and construction of vehicles as set out in the table hereunder. Vehicles complying with the requirements of ADR 44/... need not comply with Section 58.12 of this Rule.
