TMA Tow Truck Monitoring Schemes (WA)

About the scheme

The TMA Tow Truck Monitoring Schemes (WA) are made available by Main Roads Western Australia (MRWA), to enable monitoring of the movements, mass and position-derived speed of eligible Heavy Lift Tow Trucks on the Western Australian road network.

This scheme group consists of two schemes:

  • TMA Tow Truck Up to 21t Tandem Drive or Up to 23.5t Tri-Drive Monitoring Scheme (WA)
  • TMA Tow Truck Up to 23t Tandem Drive or Up to 27t Tri-Drive Monitoring Scheme (WA).

The scheme associated with the Telematics Monitoring Application (TMA) of the National Telematics Framework.

Definitions

The schemes define a ‘Heavy Lift Tow Truck’ as a tow truck equipped with a crane used or intended to be used for the lifting, salvaging or towing of heavy vehicles.

Eligibility

To participate in the schemes, a transport operator must conform with the requirements specified within the instrument of access approval, which consists of a Western Australian government permit. Eligible vehicles are defined in the instrument of access approval.

How to enrol

Step 1 – Choose a certified Application Service Provider (ASP) and assist the ASP with any information it needs to complete the enrolment process. The ASP must be certified to provide services for TMA with the Smart OBM feature.

Step 2 – Your ASP will ensure the telematics device is installed in your vehicle and certified by TCA. The telematics device will generate position records and report them to TCA.

Step 3 – Eligible vehicles must be fitted with a TCA-approved Smart OBM system. The Smart OBM system used in the scheme will generate mass and configuration records. Confirm with the service provider that a Smart OBM system is installed on the prime mover and trailers and is paired to operate with that certified service provider. The ASP will report data records and enrolments to TCA.

Frequently asked questions

The TMA Tow Truck Up to 21t Tandem Drive or Up to 23.5t Tri-Drive Monitoring Scheme (WA) monitors ‘lighter’ Heavy Lift Tow Trucks, which include:

  • Tandem Drive Over Mass Heavy Lift Tow Trucks with more than 16.5 tonnes on the drive axle group but no more than 21 tonnes on the drive axle group
  • Tri-Drive Over Mass Heavy Lift Tow Trucks with more than 20 tonnes on the drive axle group but no more than 23.5 tonnes on the drive axle group.

The TMA Tow Truck Up to 23t Tandem Drive or Up to 27t Tri-Drive Monitoring Scheme (WA) monitors ‘heavier’ Heavy Lift Tow Trucks, which include:

  • Tandem Drive Over Mass Heavy Lift Tow Trucks with more than 21 tonnes on the drive axle group but no more than 23 tonnes on the drive axle group
  • Tri-Drive Over Mass Heavy Lift Tow Trucks with more than 23.5 tonnes on the drive axle group but no more than 27 tonnes on the drive axle group.

The telematics device in your vehicle generates position records. TCA uses the position records to derive information about your vehicle’s movement and speed.

As vehicle configuration and mass data is required by the scheme, TCA collects the data via the Smart OBM systems installed.

Your ASP will send data generated from your enrolled vehicles to TCA. TCA will make reporting available to MRWA via the Telematics Analytics Platform (TAP), in the form of interactive maps and reports.
