Accredited Mass Management Scheme (AMMS)
Allows for three (3) concessional mass levels without prescribing specific loading methods nor restricting commodity types
Orders
Are a tool to provide RAVs access to WA roads without a need for a permit. Transport Operators don't need to apply for an Order.
Agricultural Vehicles
Everything you need to know to operate an agricultural vehicle on a public road in Western Australia
Performance Based Standards (PBS)
If you want to introduce a vehicle outside the scope of an existing permit product, you can seek approval through the Performance Based Standards (PBS) scheme.
Oversize Road Trains and B Doubles
Allows for oversize prime movers and trailers (Class 3 RAVs) carrying over width/over height indivisible loads
Special Purpose Vehicle
A Special Purpose Vehicle is defined as a vehicle other than a tow truck or agricultural vehicle, built for a purpose other than carrying a load, except for water in the concrete pumps & fire trucks.
Livestock and Containerised Cargo
Are a scheme to allow the movement of extra mass when carrying containerised cargo or livestock.
Oversize Divisible Products
This permit allows for the movement of Hay, Straw, Wool and Concrete Pipes that are over-width or over-height.
Tri Drives
Allows a wide range of standard tri drive prime mover/truck and trailer combinations to operate on pre-approved roads.
Specific Access Permits
Provide particular RAVs specific access, subject to meeting certain permit requirements.
Harvest Mass Management Scheme (HMMS)
Developed to assist the grain industry with the difficulties experienced loading grain from a paddock. This is not a concessional loading scheme
Heavy Lift Tow Trucks
Provides approved tow trucks with extra mass on the drive axle groups when towing a vehicle
Block Truck
For the movement of a block truck up to 18.5 tonnes on a tandem axle and up to 24.0 tonnes on a tri axle fitted with dual tyres
Residential Construction Products
The Residential Construction Products Permit allows specific Restricted Access Vehicle (RAV) combinations to operate on roads not listed in RAV Network 1, at full statutory axle mass limits, to cart residential construction products to residential construction sites.
Short Triple Road Train
The “Short Triple Road Train Period Permit” only applies to a vehicle combination with a maximum length of 36.5 metres and consisting of axle group requirements as outlined here.
Australian Defence Force (ADF)

Aggregate Trailer Mass (ATM) Calculator
ATM Calculators are provided to assist transport operators to help ensure their trailers are sufficiently rated. ATM is the rating for a trailer, referring to the maximum trailer mass. Transport operators are obliged to ensure their trailers are suitably rated for the load being carried.
Tow Coupling D-Rating Calculator
The D-Rating Calculator allows transport operators to check and ensure their tow couplings are sufficiently rated. A vehicle combination fitted with insufficiently rated tow couplings can result in catastrophic consequences. Disclaimer: The results provided by the calculators are only as accurate as the data that is inputted by the user. Each field in the ATM Calculators and the D-Rating Calculator must be completed for accurate results.
D-Rating CalculatorTrailer Clearance Calculator
The Trailer Clearance Calculator will assist transport operators to determine the minimum gap requirement between vehicles in a combination. The Australian Standards AS2174 requires the vehicle combination to have sufficient clearance to allow the trailers to move through all angles of articulation, pitch and roll.
Trailer Clearance CalculatorStatic Rollover Threshold Calculator
The SRT Calculator helps transport operators to assess the rollover risk of their vehicle configuration and load. This then allows operators to either adjust the load accordingly or ensure there are suitable controls in place to mitigate the risks.
