The Queensland Department of Transport and Main Roads (TMR) has released the first network map for zero-emissions heavy vehicles (ZEHV).

The map focuses on the southeast corner of the state, extending from the New South Wales border at the Gold Coast to Bundaberg and as far west as Toowoomba and Warwick.

It includes selected, but not all, state-controlled roads within this area.

A Department spokesperson says TMR and the NHVR (National Heavy Vehicle Regulator) will continue working with local governments to include appropriate council roads on the new ZEHV network to enable first and last-mile connections for industry.

HVIA can also reveal access to the ZEHV network will be limited to three-axle rigid trucks and three-axle prime movers with a maximum vehicle mass limit of 25.5 tonnes; and three-axle prime movers towing up to three-axle semi-trailer combinations with a maximum combined mass limit of 45.5 tonnes.

The TMR spokesperson says both vehicles will be allowed to operate at masses of up to eight tonnes on the steer axle; and 18.5 tonnes on the tandem drive axle.

This is 1.5 tonnes additional on the steer axle and two tonnes additional on the tandem drive, however, the overall mass increase is limited to a maximum increase of 2.5 tonnes.

The spokesperson also confirms both vehicles will be required to meet certain axle spacing and tyre size requirements to assist in mitigating impacts to the network.

Vehicles will also be required to be equipped with telematics monitoring applications, on-board mass systems and road-friendly suspension.

These systems will support TMR to better understand the impacts additional mass may have on the state-controlled network, the spokesperson says.

In consultation with the NHVR, TMR is seeking alignment to the recently-announced ‘Safer Freight Vehicles’ for new low- and zero-emissions vehicles irrespective of the width.

This includes devices for indirect vision and lane departure warning systems. Converted vehicles will also need to meet a minimum set of safety requirements that are currently being finalised.

The move comes in the wake of the NHVR assuming responsibility for heavy vehicle on-road compliance and enforcement in the Sunshine State. More details on that change here.
