Update to heavy vehicle permits for log trucks

  • 01 Apr 2016

In December last year we advised the transport industry of some changes to the permit issuing process to remove some irregularities and ensure safety and consistency in the way we assess heavy vehicle permit applications. This included the policy governing the requirement of Roll Stability Control (RSC) in permits.

Unfortunately this led to some confusion amongst the log transport industry, who have been exempt from the need for Roll Stability Control under the Heavy Vehicle Brakes Rule. We have made a further change to our permitting policy to remove this confusion and clarify the requirements from 1 April 2016 for log transport trailers.

The new policy reads:

Trailer Roll Stability Control (RSC): The trailer(s) if first registered on or after 1 May 2010 must have roll stability control fitted and active; that is an Electronic Brake System (EBS) with the roll stability control function turned on. Alternatively if the trailer(s) were first registered before 1 May 2010 or are log trailers carting round wood first registered before 1 April 2016 and do not have EBS and RSC – these must instead operate with a minimum Static Roll Threshold (SRT) of 0.4 g, provided SRT compliance documentation is kept with this permit and produced to enforcement officers.
