Coalfields Highway - Revised conditions for the AB-Triple (36.5m) Roelands Hill Trial

Main Roads Heavy Vehicle Services would like to advise transport operators that the requirements for participation in the AB-triple (36.5M) Roelands Hill Trial have been reviewed to encourage participation, while continuing to ensure safe access.

The revised access conditions are as follows:

  • All vehicles must be installed with Transport Certification Australia (TCA) type-approved telematics in-vehicle units    which can support the application of Hill Descent Monitoring (HDM).
  • All vehicles must be enrolled under the application of HDM using a TCA Certified Service Provider to ensure all vehicles stop in the heavy vehicle inspection bay at the top of Roelands Hill to check brakes, commence descent in the appropriate low gear and not exceed a maximum speed of 40 km/h when descending Roelands Hill. These actions are essential to minimise braking temperatures and risk of brake failure.
  • All vehicles must be fitted with and utilise an auxiliary braking system when descending Roelands Hill.  Drivers must be familiar with the operation of the particular auxiliary braking system. This is also essential to minimise service brake temperatures and risk of brake failure.
  • The prime mover in the participating vehicle combination must be fitted with an Antilock Braking System (ABS) or Electronic Braking System (EBS).
  • The trailers in the participating vehicle combination must be fitted with a Trailer Electronic Braking System (TEBS) with a Rollover Stability System (RSS); this will ensure improved braking performance and stability under braking.
  • One forward facing camera and one rear-facing camera must be mounted on the prime mover.  The rear-facing camera must be positioned on the driver’s side of the prime mover. This will assist Main Roads to identify the cause of any incidents that may occur and monitor the impact on other traffic.
  • Vehicles 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.
  • The operator must participate in brake temperature testing and ensure drivers are cooperative during the testing. This will only occur on occasion and will only delay the vehicle for a short time. This is an essential part of the trial required to validate simulated braking temperature results.

Transport operators who wish to participate in the trial are required to complete the AB-triple (36.5m) Roelands Hill Trial Permit Application form available on the Access Trials page on the Main Roads website.

For further information in relation to the trial please visit the Access Trials page on the Main Roads website.  Alternatively, you can contact the Heavy Vehicle Helpdesk on 138 486 or email hvs@mainroads.wa.gov.au.
