At the request of our customers, Main Roads Heavy Vehicle Services (HVS) has reviewed the Policy & Process for the Provision of Traffic Escort Services, with a view to allow mass and dimension amendments to be submitted within 14 days of the time traffic escort services are to be provided. 

While it is expected that transport operators will make every effort to submit initial permit applications with accurate mass and dimensions, HVS appreciates the mass and/or dimensions can differ once loading is completed due to a number of reasons.  

As such, the policy has been updated to allow mass and dimension amendments to be submitted within 14 days of the time the services are to be provided. The policy has also been updated to clarify when an amendment fee will be applied. 

The Policy & Process for the Provision of Traffic Escort Services is available on the Traffic Escorts page and the News & Information page on the Main Roads website.

For further information, please contact the Heavy Vehicle Services Helpdesk on 138 486 or email hvs@mainroads.wa.gov.au .
