Albany Highway - A-double (36.5m) Bedfordale Hill Access Trial

Main Roads Heavy Vehicle Services would like to invite transport operators to participate in an A-double (Prime mover, semi-trailer towing a dog trailer) 36.5m access trial on Bedfordale Hill. The trial will provide specific access on Albany Highway, between the Bedfordale Road Train Assembly Area and Armadale Road, as well as Armadale Road from Albany Highway to Tonkin Highway, as shown on the below map. This will provide transport operators with improved access to the metro area by removing the requirement for drivers to break down these particular vehicle combinations at the Bedfordale Road Train Assembly Area.

Eligibility to participate in the trial is subject to the following conditions:

  • A-double combinations consisting of tri axle trailers and a tri axle dolly may operate up to Concessional AMMS Level 3 mass limits provided transport operators have a valid AMMS permit issued to the vehicle, which must be used in conjunction with the trial permit. A-double combinations consisting of tandem axle trailers and/or a tandem axle dolly will be restricted to statutory mass limits.
  • 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 Bedfordale Road Train Assembly Area to check brakes, commence descent of Bedfordale Hill in the appropriate low gear and not exceed a maximum speed of 40 km/h when descending Bedfordale 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 Bedfordale 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.
  • Vehicles must be fitted with a driver fatigue and distraction monitoring system with appropriate governance in place to ensure events are managed effectively.
  • One forward facing camera and one rear-facing camera must be mounted on the prime mover and must operate in accordance with the Hill Descent Monitoring (HDM) Video Recording Requirements available on the Access Trials page on the Main Roads website. 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.
  • The prime mover must be fitted with an engine that meets emission standards as specified in the Vehicle Standard (Australian Design Rule 80/03 - Emission Control for Heavy Vehicles) 2006 (equivalent to Euro 5 Standards). This assists in reducing emissions and exhaust noise when descending steep gradients under auxiliary braking.
  • 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.
The trial will run for an initial period of 12 months and transport operators who wish to participate are required to complete the A-Double (36.5m) Bedfordale Hill Access Trial Permit Application form available on the Access Trials page on the Main Roads website.

For further information regarding 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.
