Do I need an Oversize Overmass (OSOM) Permit?
You may 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.
The NHVR processes ALL Oversize Overmass permit applications for travel within and between the Australian Capital Territory, New South Wales, Queensland, South Australia, Tasmania and Victoria through the NHVR Portal.
For travel within the Northern Territory and Western Australia you need to apply directly to the relevant state or territory road transport authority.
Please note that VicRoads has updated pilot requirements in Victoria. For more information read the Guide for pilot requirements in Victoria information sheet (PDF, 221KB).
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.
Gazette notices, permits, and in some cases other laws outside of the Heavy Vehicle National Law, sometimes require third parties and other entities to be contacted and/or consulted to provide permission for travel.
Pilots and escorts
- Providing permit copies to pilot and escort vehicle drivers (PDF, 197KB) - Heavy vehicle operators must provide a copy of their permit to any pilot or escort vehicle driver accompanying them.
- Pilots and escort training and recognition (PDF, 230KB) - Provides a overview of the pilot and escort requirements in all jurisdictions.
State and territory road transport authorities regulate all aspects of piloting/escorting, including who may operate as a pilot/escort vehicle driver and when they are required to accompany a load, except for Victoria.
Victoria escort services
In Victoria only, the NHVR provides escort services to the over-dimensional transport industry (all other aspects of piloting/escorting remain with VicRoads).
NHVR Safety and Compliance Officers in Victoria:
- provide escorts for vehicles carrying very large items
- conduct compliance check against permits.
Charges
The charge-out rate for these services is $227 per hour (including GST), with a minimum charge of two hours for weekdays and three hours for weekends and public holidays. These rates and conditions are consistent with those previously applied by VicRoads.
Charging starts from the time of the booking to attend at the pick-up point of the escort until completion of the service. The charge-out rate is the reasonable cost of providing the service and will be reviewed annually.
Cancellation fee
A cancellation fee applies for notice of cancellation received less than 24 hours prior to the service. Minimum charges of two hours on weekdays and three hours on weekends and public holidays will be applied.
Booking a vehicle escort
Before you book an escort service, ensure you have a permit for the journey as bookings cannot be done without a permit. Please also ensure invoices for previous bookings have been paid by the due date.
Please email HVescorts@nhvr.gov.au or call 0417 091 454.
