Commodity freight is bulk primary products that are transported on a seasonal or low frequency basis from the place of production to the place of processing.
While commodity routes may be of a lesser standard than general freight routes, they must meet certain standards to protect the road infrastructure and ensure road safety.
Specific conditions of commodity routes may include:
- travel limited to seasonal operation only, for example to align with harvest season
- restricted to a particular commodity
- time restrictions to minimise environmental and amenity impacts
- speed restrictions to prevent infrastructure damage and maintain vehicle stability and safety on rough or unsealed roads
- use of yellow revolving flashing lights fitted to the vehicle to warn oncoming motorists where the road may be narrow and sight distance limited
- the requirement to slow down, stop or give way to other road users at intersections or cross roads where a restricted access vehicle may be undertaking a turning manoeuvre.
The goods that have been approved for transport on commodity routes include:
- fertiliser - a product or substance in dry, pellet or liquid form which may be added to soil to improve its fertility
- logged forest timber - raw or unprocessed felled trees
- grain - a small hard seed of cereal or grass plant - eg wheat, rye, oats
- milk - the raw milk product from a cow or other milk producing animal used for food or making cheese
- hay and bulk stockfeed - grasses/plant matter cut and dried for use as animal feed or loose unpackaged grain or pellet form animal feed
- wine/grapes - fermented grape juice used in the production of wine or harvested grapes
- livestock - farmed animals - eg cattle, sheep and pigs which are raised for sale or profit
- baled wool - compressed fleece from animals such as sheep and goats
- fresh fruit and vegetables - unprocessed/unpackaged raw fruit or vegetables transported from the farm to packaging plant or processor.
