Oversize Overmass permit

Do I need an Oversize Overmass Permit?

You will need to apply for a class 1 Oversize Overmass (OSOM) permit if your OSOM combination does not comply with a mass, dimension or operating requirements set out in a gazette notice.

To apply for an Oversize Overmass permit:

PLEASE NOTE: Operators should check that their vehicle complies with the schedules and conditions in the relevant gazette notice as the permit relevant to this application will reference these same conditions.

Checklist - Oversize Overmass permit application

To speed up your application process and to minimise requests for further information, the NHVR recommends you check the following:

 NHVR PortalPDF applications
Applications are fully completed The NHVR Portal will automatically flag any incomplete fields in your permit application. If any sections are incomplete or ineligible, it will be returned to you for finalisation or improvement before we are able to process the permit application.
Applicant details Use the NHVR Portal to keep your company or individual particulars up to date at all times. The NHVR Portal will automatically fill in the relevant information based on your account details. Be sure to use the same company name every time. Applying under different company and trading names will delay your application.
Regulator Customer Number (RCN) Your RCN is linked directly to your ABN to ensure all of your applications for permits are in one place. If you don't have an RCN, it will be created for you the first time you register for the NHVR Portal. If you have an RCN you do not need to complete Section 1 of the applcation form.
Vehicle details and dimensions

The Vehicle Configurations tool allows you to interactively build your vehicle to the required configuration and save these details for re-use on future permit applications.

When completing the vehicle details, particular attention should be given to ensure the vehicle registration numbers are correct and a clear description of the vehicle.

Please ensure you have completed Section 4 of the application form correctly. Incomplete or unreadable information will be returned for your completion and delay the processing of your application.

When completing the vehicle details, particular attention should be given to ensure the vehicle registration numbers are correct and a clear description of the vehicle.

Please complete the table to include the GCM for the prime mover and the ATM of the trailer. This information can be found on the vehicle compliance plate, manufacturer’s rating letter or on your vehicle registration certificate.

Loaded axle mass and spacings

If relevant the Vehicle Configurations tool will prompt you to complete the loaded axle mass and spacings details for your vehicle.

The loaded axle mass and spacings table needs to be completed ONLY if your combination is overmass.

Permit type

If you are applying for a period permit for multiple states, please be aware that a period permit is only applicable to certain OSOM combinations (such as prime mover low loader combination or prime mover, low loader dolly and low loader combination). The OSOM combination that you are applying for may only be eligible for a single trip permit depending on the dimensions and mass of your OSOM combination.

Route/area details

You can nominate and save the intended route on the NHVR Journey Planner. The journey can be saved with a Journey ID and referencing this number will improve the NHVR’s processing time for your permit.

If the Journey Planner is not utilised you must supply a full route description (which includes a turn by turn analysis, listing ALL roads travelled on including the town and suburb information) or attach a clear map of the intended route with your application.

When completing the start address and destination address fields, please supply the full address including the street number.

If the requested journey traverses through the Northern Territory or Western Australia, you must also contact the relevant state or territory road transport authority to obtain the required permit for the journey within that jurisdiction.

Third-party approvals

You may be required under law to consult with one or more other entities and seek their approval in relation to your application e.g. rail networks, energy providers, telecommunication networks.

If third party approval is required for your movement, please submit a copy of the approval/s with your application.  If using the new NHVR Portal, the approvals can be easily uploaded under Step 4 Attachments, and then it will be lodged with your application once it is completed and submitted.

If you are unable to provide all required third party approval/s with your application, please submit as soon as possible via email, fax or post clearly marked 'Access Management - Third Party Approval Evidence' - quoting the case number and your RCN. Emailing your third party approval/s to accessenquiries@nhvr.gov.au is the preferred option and will speed up the application process.

PLEASE NOTE: The relevant road manager/s may commence their decision making process, however the NHVR cannot grant your permit until you provide evidence that approval has been given by the third party entity.

Transport Management Plan

A Transport Management Plan (TMP) may be required for your OSOM movement. Operators should check with the relevant state or territory road transport authority to find out whether a TMP is required for their permit application. Information on when a TMP is required for movement through New South Wales can be found here.

If a TMP is required, please submit with your application.

Operating requirements in Queensland

If your combination is overmass and travels through Queensland, you may be required to register as an Approved Heavy Vehicle Haulage Operator (AHHO) and complete a Load Mass Declaration. The Department of Transport and Main Roads will contact you directly if this is required for your movement.

Route assessment fee The NHVR will notify you if the Road Manager is required to undertake a route assessment and if any assessment fee is payable to that Road Manager. Payment of this assessment fee is required to be managed between yourself and the Road Manager. 
Signature There is no need to provide a physical signature as the NHVR Portal recognises your unique user profile and therefore knows who lodged the application. You will be required to check a box declaring that all details in the application are true and correct. The terms of use for the NHVR Portal cover the requirement around signatures when you first access the Portal. Each application is required to be signed before it can be processed (digital signatures are permitted). If your application is not signed you will be advised to re-send another signed application page before your permit is processed.
Application payment

The application payment is a non-refundable application processing fee. The fee applies whether a permit is issued or not, including where a journey is covered by a Notice and doesn’t require a permit.

Payment of the application fee is available using debit card or credit card (Visa, Mastercard or American Express). It is done as the final simple step of the application submission.

The application payment is a non-refundable application processing fee. The fee applies whether a permit is issued or not, including where a journey is covered by a Notice and doesn’t require a permit. A permit cannot be issued without full payment of the required fees.

Payment can be made by credit card (Visa, Mastercard or American Express) or cheque. Credit card payments are the preferred payment option and will speed up the application process.

Application submission The quickest way to submit applications is through the new NHVR Portal. The NHVR Portal will notify you that your application has been sucessfully submitted.

Submit your application ONCE only. If you submit your application more than once through multiple channels, this will slow processing down while we make sure we are working on the right application for you.

Submit only one application per fax. Each application will need to be sent through on a separate fax.
