Public Holiday Curfews for Oversize Vehicles

The Public Holiday Curfews applying to oversize agricultural vehicles have recently been reviewed.

Curfews have applied to oversize vehicles for the past 15 years, due to the increased risk associated with high volumes of tourist traffic, who are travelling on unfamiliar roads and are not familiar with the movement of oversize vehicles.

Following discussions with agricultural industry representatives, the curfew applying to oversize agricultural vehicles has been lifted on all roads except Perth metropolitan roads and 11 major regional roads. The revised curfew only applies to oversize agricultural vehicles in excess of 5.5 metres in width.

An overview of the revised curfews applying to oversize agricultural vehicles is available below. The curfews will be stipulated in the relevant Permit or Order operating conditions.

Revised Public Holiday Curfews for Oversize Agricultural Vehicles

Do You Need a Permit? 

A Permit or Order is required from Main Roads when driving an agricultural machine or towing an agricultural implement in excess of the mass and dimension limits prescribed in Part 8 of the RTVRs on a public road. Generally speaking, whenever an agricultural machine, implement or combination exceeds any of the following limits, it must be operated in accordance with a Permit or Order.

  • 2.5m in width
  • 4.3m in height
  • 12.5m in length for a rigid vehicle
  • 19m in length for a combination
  • 42.5t gross mass
  • 6t on a single steer axle
  • 10t on a twin steer axle group (non-load sharing suspension)
  • 11t on a twin steer axle group (load sharing suspension)
  • 9t on a single axle
  • 16.5t on a tandem axle group
  • 20t on a tri or quad axle group

You do not need a permit if your agricultural machine or agricultural combination is covered by any of the following Orders. If your agricultural machine or agricultural combination falls outside the parameters of the Orders, you must apply for a Permit.

Available Orders  

Agricultural Combinations

The Agricultural Combinations Order 2019 allows applicable agricultural combinations to operate on any road within Western Australia, except a Freeway.  

An agricultural combination must be operated in accordance with the Restricted Access Vehicle Agricultural Combination Operating Conditions.

An agricultural combination operating under the Agricultural Combinations Order 2019 and exceeding any of the following mass limits must not cross a bridge, unless the operator obtains a bridge crossing permit:

  • 9t on a single axle
  • 16.5t on a tandem axle group
  • 20t on a tri or quad axle group
  • 42.5t gross mass

Agricultural Machines 

The Agricultural Machine Order 2018 allows applicable agricultural machines to operate on a road outside the Perth Metropolitan Area without the need to obtain a permit.  

A wheeled agricultural machine must be operated in accordance with theRestricted Access Vehicle Agricultural Machine Operating Conditions.

Rubber tracked agricultural machines that are oversize or over mass must operate in accordance with theRestricted Access Vehicle Rubber Tracked Agricultural Machine Operating Conditions.

The Agricultural Machine Order is subject to a list of Restricted Bridges. An over-mass agricultural machine must not cross any of the bridges listed in theAgricultural Machines Restricted Bridges unless a Bridge Crossing Permit has been obtained.

Five in One Bins

The Five in One Agricultural Bins Notice 2003 allows motor vehicles fitted with 'five in one agricultural bins', manufactured for the purpose of carrying different types of bulk seed and fertiliser, to operate with a width up to 2.8 metres, without the need to obtain a permit.

Available Permits  

Agricultural Combinations Bridge Crossing

An Agricultural Combinations Bridge Crossing Permit is issued to allow an agricultural machine or agricultural combination to cross a bridge that is not allowed to be crossed under an Order. 

Either a Single Trip Permit, or a 12 month Period Permit may be issued, depending on the needs of the operator. If a particular agricultural vehicle or combination only needs to be moved on the rare occasion, the operator can apply for a Single Trip Permit. If an agricultural vehicle or combination will undertake multiple journeys on the road, or if the self-propelled towing vehicle will tow a range of agricultural implements, the operator can apply for a 12 month Period Permit.

NOTE: To assist with identifying the location of bridges, the Structures Web App is available on the Main Roads website, which provides the location of all structures in Western Australia.

Agricultural Vehicle

The Agricultural Vehicle Permit provides for the movement of a self-propelled agricultural vehicle that exceeds a statutory mass and/or dimension limit and is unable to operate within the parameters of the Agricultural Machine Order. Depending on the mass of the vehicle and the requested route, either a Single Trip Permit, or a 12 month Period Permit may be issued.

Agricultural Vehicle Combination

The Agricultural Vehicle Combination Permit provides for the movement of a self-propelled vehicle towing up to three agricultural implements in combination, exceeding statutory mass and/or dimension limits and unable to operate within the parameters of the Agricultural Combinations Order. Depending on the mass of the vehicle and the requested route, either a Single Trip Permit, or a 12 month Period Permit may be issued.

Applying for a Permit

Registering as an Operator

If this is your first time applying for a permit and you have not previously registered as an operator, you will need to complete and submit the Restricted Access Vehicle Operator Registration form.

NOTE: Agricultural vehicle operators do not need to be accredited under the WA Heavy Vehicle Accreditation Scheme.

Registering a Vehicle for a Permit

Permits will be issued to the self-propelled towing vehicle. As such, each self-propelled towing vehicle that requires a permit will need to be registered in our permit system. You will need to complete and submit the following form to register the vehicle.

Agricultural Pilot Requirements

(Click the above image to access the Agricultural Pilot Requirements Flow Chart)

When moving an oversize agricultural vehicle, including a machine, towed agricultural implement or agricultural combination, pilot vehicles may be required to facilitate the safe movement. The Agricultural Pilot Authorisation 2019  allows pilots to accompany an oversize agricultural vehicle, up to 8.5 m in width, without the need to hold a Heavy Vehicle Pilot Licence, subject to the conditions of the Authorisation.

The Agricultural Pilot Requirements Flow Chart outlines the pilot requirements when moving an oversize agricultural vehicle. These pilot requirements will also be stipulated in the relevant Main Roads Order or Permit.

An Agricultural Pilot operating under the Heavy Vehicle Agricultural Pilot Authorisation must comply with the requirements in the Agricultural Pilot Operational Requirements.

Agricultural Pilot Zones  

The Agricultural Pilot Requirements Flow Chart specifies pilot requirements depending on the zone the oversize agricultural vehicle is travelling in. The pilot requirements vary for each zone, as the risks to road users vary due to different traffic volumes and mix of traffic.

 The Agricultural Pilot Zones are defined as follows:

  • Green Zone - All roads within the areas bounded by Regional Distributor and State roads.
  • Orange Zone - All Regional Distributor and State roads, outside the Perth Metropolitan Area.
  • Red Zone - All roads within the Perth Metropolitan Area.

 The following map provides a high level view of the Agricultural Pilot Zones. The zones are published in more detail on the RAV Mapping Tool .

The following document provides a list of all Regional Distributor road and State roads, i.e. roads that make up the Orange Zone:

Traffic Management Requirements

Agricultural vehicles may travel between paddocks from one gate to another gate, within 1km on the same local government road, provided there is traffic management in place. The following document outlines the traffic management requirements:

Traffic Management Requirements - Towed Agricultural Implements Crossings - (Ref Number 07/2071 D07#103477)

Police Permit (MR19)  

When moving ‘excessively large‘ agricultural machinery or towed implements you must obtain an MR19 permit from WA Police in addition to the Main Roads Permit or Order requirement.  Whilst the Main Roads Permit or Order accounts for the mass and or dimension modification, the MR19 permit is an instrument to ensure local police are notified of the movement of excessively large agricultural machines or towed implements that could impact on the localised road network. This enables WA Police to ensure the proposed movements are not unsafe in their opinion and to take other local factors into consideration such as potential impacts on emergency vehicle access, as the road(s) will essentially be blocked.
