Road Manager Toolkit - Road Trains and Higher Mass Limits heavy vehicles

The Road Manager Toolkit is designed to assist local councils in responding to road manager consent requests for heavy vehicle road access from the National Heavy Vehicle Regulator (NHVR) for Road Trains and Higher Mass Limits (HML) heavy vehicles.

The Toolkit comprises of:

Please note the information contained in the Road Manager Toolkit is intended as a guide only for other road managers. The information has been prepared based on the practices of Roads and Maritime which may change from time to time. Road managers should undertake their own research and not solely rely on the information provided in this Toolkit.

Background

Under the Heavy Vehicle National Law (HVNL) and co-delegation arrangements in NSW, only the NHVR can issue a road access permit for a Class 2 heavy vehicle.

The definition of a Class 2 heavy vehicle is contained in section 136 of the HVNL. Common types of Class 2 heavy vehicles include semitrailers, B-doubles, road trains, Performance Based Standards (PBS) heavy vehicles and heavy vehicles operating at Concessional Mass Limits (CML) and HML.

If a Class 2 heavy vehicle does not operate under a Notice because it is travelling on a route that is not contained in a Notice, an operator will submit an application for a road access permit to the NHVR. Once the NHVR receives an application it will then seek the consent of all road managers on the proposed route. A road manager can respond by either:

  • Granting consent with no access conditions,
  • Granting consent with access conditions; or
  • Refusing consent.

Under section 172 of the HVNL, a road manager that refuses consent or provides consent with conditions must provide the NHVR with a statement to explain the reasons for their decision. If the NHVR receives the consent of all road managers on the proposed route, the NHVR can issue a road access permit to the operator.

Application of standard access conditions for Higher Mass Limits (HML) and Road Train access requests

The five steps below demonstrate how to respond to an access request using the example of a 4.6m high HML B-double as an example through applying the Roads and Maritime Standard Access Conditions – Road Trains and Higher Mass Limits heavy vehicles.

  1. Road Manager Consent Request received from NHVR
    The NHVR will email a road manager consent request to a road manager if a transport operator requests to travel on a route that includes a road managed by the road manager. The email will include specifications of the vehicle, including vehicle details, axle spacings and vehicle registration information, along with an attached Written Road Manager Consent form to complete to use to respond to the access request.
  2. Identify the type of heavy vehicle
    The Roads and Maritime Class 2 Heavy Vehicle Diagrams lists common Class 2 heavy vehicles type. In this instance, a B-double is listed in the second row of the table.
  3. Identify in the excel spreadsheet the access conditions that apply to that particular heavy vehicle
    The Roads and Maritime Standard Access Conditions – Road Trains and Higher Mass Limits heavy vehicles spreadsheet contains standard access conditions that are categorised by vehicle type for HML heavy vehicles and road trains operating on Roads and Maritime managed roads. These conditions are indicative of the access conditions that Roads and Maritime applies and may not be exhaustive. Identify the permit conditions in the tab labelled 4.6m HML B2.
  4. Additional access conditions
    Additional access conditions may be required to suit local conditions and specific details of the particular heavy vehicle, for example, travel restrictions on specific bridges and roads.
  5. Complete the Written Road Manager Consent form
    Complete the Written Road Manager Consent form provided by the NHVR to indicate if you consent to the access request, consent to the access request with conditions or refuse consent and provide a statement of reason, if required. See sample Roads and Maritime Written Road Manager Consent form with the conditions for a 4.6m high HML B-double for a practical example. When completed send to the NHVR. Please note that under section 156 of the HVNL, a road manager has 28 days to respond to an access request.

Sample Road Manager Consent Form

The sample written statement of road manager consent provides an example using the Roads and Maritime Standard Access Conditions for a 4.6 metre high HML B-double.

Standard Access Conditions – Road Trains and Higher Mass Limits heavy vehicles

The Standard Access Conditions spreadsheet (XLS, 213Kb) contains the access conditions that are indicative of the conditions that Roads and Maritime applies to heavy vehicle access requests for Class 2 Road Trains and HML heavy vehicles. This spreadsheet is intended as a guide for other road managers. Other conditions may be required to suit local conditions and the particular characteristics of the heavy vehicle.
