LEGISLATIVE PROVISIONS\n    1.  Name of Standard\n        1.  This standard is the Vehicle Standard (Australian Design Rule 35/07 – Commercial Vehicle Brake Systems) 2022.\n        2.  This standard may also be cited as the Australian Design Rule 35/07 – Commercial Vehicle Brake Systems, the Australian Design Rule 35/07, or ADR 35/07.\n2.  FUNCTION\n    1.  The function of this standard is to specify braking requirements on commercial vehicles and large passenger vehicles to ensure safe braking under normal and emergency conditions.\n3.  APPLICABILITY\n    1.  This vehicle standard applies to category LEG, MB, MC, MD, ME, NA, NB and NC vehicles; from the dates set out in clauses 3.1.1 to 3.1.4 and the table under clause 3.10 below.\n        1.  1 October 2023 for all sub-category NB2 and category NC vehicles, with an ‘Overall Width’ exceeding 2,500 mm.\n        2.  1 November 2023 for all new model vehicles.\n        3.  1 November 2024 for all category LEG, MB, MC, MD, ME and NA vehicles.\n        4.  1 February 2025 for all category NB and NC vehicles.\n    2.  For the purposes of clauses 3.1.2 above, a “new model” is a vehicle model first produced with a ‘Date of Manufacture’ on or after the date prescribed in that clause.\n    3.  Category MB, MC or NA vehicles complying with the requirements of the Australian Design Rule 31/…[\\[1\\]](#_ftn1) – Brake Systems for Passenger Cars will be accepted as complying with this standard.\n    4.  Category LEG vehicles that are fitted with a single foot pedal controlling both front and rear service brakes must comply with all requirements of this standard applicable to category NA vehicles. Other category LEG vehicles must comply with the Australian Design Rule 33/…1 – Brake Systems for Motorcycles and Mopeds.\n    5.  This standard does not apply to combinations of drawing vehicle and trailer.\n    6.  A vehicle comprising two or more non-separable articulated units must be considered as a single vehicle for the purposes of this standard.\n    7.  Category MB, MC and NA vehicles certified to this standard must also be certified to the Australian Design Rule 88/…1 – Electronic Stability Control (ESC) Systems and the Australian Design Rule 89/…1 – Brake Assist Systems (BAS).\n    8.  Category NA vehicle types approved to the United Nations Regulation No. 13 – UNIFORM PROVISIONS CONCERNING THE APPROVAL OF VEHICLES OF CATEGORIES M, N AND O WITH REGARD TO BRAKING, incorporating the 11 series of amendments, will be deemed to comply with this standard.\n    9.  Category MD, ME, NB and NC vehicle types approved to the United Nations Regulation No. 13 – UNIFORM PROVISIONS CONCERNING THE APPROVAL OF VEHICLES OF CATEGORIES M, N AND O WITH REGARD TO BRAKING, incorporating the 11 series of amendments, will be deemed to comply with this standard, provided that the requirements of clauses 5.3.5, 5.3.6, 5.3.7, 5.8.1.1, 5.8.2 and 8.12.6(b) (where applicable) are met.\n\n  \n\n1.
