Urgent need for a single national Class 1 Notice with practical limits

By July 12, 2017April 6th, 2018Media Releases - July 2017

The current state-based red tape for heavy agricultural vehicles needs to be removed and a practical national notice introduced this year to enable farmers to get on with the business of farming, says national grain farmers representative body, GrainGrowers.

Individual state notices and rules governing the movement of heavy farm machinery on public roads are out of touch with the size of modern equipment, GrainGrowers has demonstrated.

A major survey of farmers by GrainGrowers over recent months investigated the dimensions and configurations of the heavy vehicle fleet operating in the grains industry. More than 800 farmers across the country participated in the survey, providing hard evidence of the true size of modern grain machines which are now routinely being used on farms.

GrainGrowers has taken the survey results to the National Heavy Vehicle Regulator (NHVR), to support their work in developing a single national notice which contains limits and allowances that are consistent across the country and practical from the farmers’ perspective.

A single national Class Notice has been welcomed by GrainGrowers’ National Policy Group (NPG) members who hope it can be fast tracked in time for the winter crop harvest.

NPG has also welcomed the NHVR’s approach to aim for limits which would cover 80 per cent of vehicles and acknowledged that the draft NHVR limits under the proposed Notice were much closer than the existing state notice limits.

“However, further tweaking is definitely required,” GrainGrowers CEO David McKeon said.

“Grower feedback from around the country and our recent survey show some limits need to be increased to accommodate the current fleet. These include single vehicle length and height limits as well as rear overhang allowances.

“The fact that such a large number of farmers across the country have engaged with this issue – at a busy time when new crops were being sown – shows how aware they are of the glaring discrepancies between the state regulations and the dimensions of the vehicles they operate and how important it is that this issue be resolved in the national Notice.”

“What’s especially important is that state road agencies and local councils (who own many of the roads) work with the NHVR to support these changes and get the national notice in place as soon as possible.”

The survey results point to the need for change to the proposed:

  • Single vehicle length limit of 15 metres: Only 30 per cent of single vehicles are under 15 metres in length, with an average length of 20 metres and a significant percentage between 20 and 30 metres long. More than 54 per cent of augers or conveyors are more than 15 metres, but under 19 metres, in length but a 25 m limit is needed to cover 80 per cent of all vehicles in use.
  • Vehicle height limit of 4.6 metres: only 37 per cent of vehicles are 4.6 metres high or less while only 60 per cent of vehicles would fit within a 5 metre height limit. Sixty per cent of respondents said there were no overhanging powerlines on their standard routes which would restrict the safe height of vehicles they use.
  • Auger rear overhang of 9 metres – nearly a quarter of the current fleet has an overhang of more than 9 metres. The range for those vehicles above nine metres is 9.4 – 17 metres.

Surveyed growers also made general comments on the heavy vehicle laws saying there was:

  • An urgent need for a simple, easy to understand single national system
  • Lack of, or insufficient time for, notification of changes
  • Conflicting information from different agencies about the rules which apply
  • Concerns about pilot and escort requirements
  • Need for the road infrastructure to be better maintained and for trees to be trimmed
  • Need for education and awareness programs for other road users about agricultural vehicles.

“The NHVR is expected to release a discussion paper, with the proposed dimension and mass limits, this month,” said Mr McKeon.

“We are hopeful the NHVR will take note of growers’ concerns expressed in our survey results and make practical amendments to the limits.”
