Great Eastern Highway – Ongoing Permit Access for A-Double 36.5 Metre Combinations on Greenmount Hill

Main Roads Heavy Vehicle Services (HVS) advises that 36.5 metre A-Doubles, operating up to AMMS Level 3 concessional mass limits are now approved to operate on the section of Great Eastern Highway between the Northam Road Train Assembly Area (RTAA) and Roe Highway Midvale, subject to the following conditions:

  1. Access will be granted under individual permit arrangements only, i.e. access will not be granted via the RAV Networks.
  2. HVS will consult with the Department of Transport to confirm that transporting the particular load by road does not compete with rail.
  3. Access is approved between 8:00 pm and 6:00 am only.
  4. Drivers must have a minimum of 3 years of experience in driving road trains and a good driving record. A National Police Clearance is required to confirm the driver does not have any serious traffic convictions before they are approved on the permit. The operator must continue to report any driving convictions once a driver has been approved.
  5. The prime mover must be fitted with an Antilock Braking System (ABS) and Electronic Braking System (EBS) with compatible CAN bus connection.
  6. The trailers must be fitted with a Trailer Electronic Braking System (TEBS), Rollover Stability System (RSS), and compatible CAN bus connection.
  7. The prime mover must be fitted with an engine that meets the emission standards specified in the Vehicle Standard (Australian Design Rule 80/3 – Emission Control for Heavy Vehicles) 2006 (equivalent to Euro 5 Standards).
  8. The prime mover must be fitted with a driver fatigue and distraction monitoring system to manage events effectively.
  9. The prime mover must be installed with an in-vehicle telematics unit and Main Roads Heavy Vehicle Services (HVS) must be provided direct access to the telematics monitoring system. The telematics service provider must provide weekly reports demonstrating all vehicles stop in the mandatory stopping bay at the top of Greenmount Hill to check brakes and descend at a speed of no more than 40 km/h.
  10. The prime mover must be fitted with and utilise an auxiliary braking system when descending the Hill. Drivers must be familiar with the operation of the particular auxiliary braking system, with training records provided to HVS.
  11. At least one forward-facing camera and one rear-facing camera must be mounted on the prime mover and must operate in accordance with the Restricted Access Vehicle Video Recording Requirements. The rear-facing camera must be positioned on the driver's side of the prime mover.
  12. Vehicle combinations will be restricted to travel in the left-hand lane, unless they are required to overtake a slower moving vehicle to avoid overuse of the service brake.

Further information about the eligibility requirements and the 36.5 metre Greenmount Hill Access Permit application form (PDF) is available on the Specific Access Permits page on our website.
