Type 1 A-double road trains

August 2020

Key recent changes:

  • Type 1 A-doubles, excluding livestock loads, with both a tandem-axle dolly are now able to operate on all approved Type 1 A-double road train routes on and east of the Newell Highway.
  • Type 1 A-doubles transporting livestock loads are only permitted to operate east on all approved Type 1 A-double train routes east of the Newell Highway with a tri-axle dolly at a maximum of General Mass Limits (GML) on the tri-axle dolly.
  • Type 1 A-double road trains fitted with a tandem-axle or a tri-axle dolly will no longer require road friendly suspension (RFS) on currently approved roads east of the Newell Highway operating at GML or CML mass limits.
  • Operators of road trains at Higher Mass Limits (HML) are now able to enrol in the Telematics Monitoring Application (TMA) with Transport Certification Australia (TCA). Operators continue to retain the ability use the Intelligent Access Program (IAP) as an alternative.

Information on the requirements for operating a Type 1 A-double road train in NSW is available in the Type 1-A double access fact sheet.
