Centre for Road Safety

Crashes involving heavy vehicles are often serious because of their size and weight, regardless of who is at fault.

While their numbers make up only 2.4 per cent of NSW motor vehicle registrations and 8.3 per cent of kilometres travelled by all NSW vehicles, heavy vehicles are involved in about 17 per cent of all road fatalities. We need to do everything we can to move towards zero fatalities involving heavy vehicles.

Our NSW Heavy Truck Fatal Crashes (PDF, 33Kb) has detailed information on fatalities and serious injuries involving heavy trucks.

Our safety tips for heavy vehicle drivers explain how speeding, fatigue, non-use of seatbelts and dangerous loads can lead to crashes, with heavy vehicle drivers and other road users seriously injured or killed.

Any heavy vehicle that is higher than 4.3m is considered overheight in NSW. Drivers need to make sure they know the combined height of their vehicle and its load to avoid overheight incidents.

Crash avoidance and safety technologies have helped reduce the likelihood and severity of crashes.

Licence conditions has details of some of the classifications and restrictions that apply to heavy vehicle drivers.

Monitoring compliance

You can find details of how road transport laws regarding heavy vehicles are enforced and monitored on the Roads and Maritime Services website.

The Transport for NSW 2015 heavy vehicle compliance survey provides information on the roadworthiness and compliance of heavy vehicles using NSW roads. The survey helps evaluate and refine existing heavy vehicle enforcement programs to address trends where roadworthiness performance may have declined.

M1 Pacific Motorway heavy vehicle lane restrictions trial

Roads and Maritime Services is carrying out a 12 month trial of heavy vehicle lane restrictions on the M1 Pacific Motorway from 1 November 2018. The trial on the motorway will include traffic in both directions between Wahroonga nd Kariong.

The trial is part of the NSW Government’s commitment to keeping traffic moving on one of the state’s busiest roads and aims to improve road safety, traffic flow and increase driver comfort.
