Heavy Rigid licence

A licence class allowing a driver to operate a heavy vehicle over 8 tonnes GVM with three or more axles, typically including a rigid truck and dog trailer combination.

Heavy Combination licence

A licence class permitting operation of a prime mover towing a semi-trailer, or a rigid truck towing a heavy trailer, where the combination exceeds 8 tonnes GVM.

Multiple Combination licence

The highest heavy vehicle licence class, allowing operation of B-doubles and road trains consisting of a prime mover towing two or more trailers.

Light Rigid licence

A licence class for vehicles up to 8 tonnes GVM, including small trucks and buses, with a maximum of two axles and optional light trailer.

Medium Rigid licence

A licence class for heavy vehicles over 8 tonnes GVM with exactly two axles, such as a two-axle truck or a small bus.

Registration renewal

The annual process of paying the registration fee for a heavy vehicle to keep it lawfully on the road; late payment after the grace period makes the vehicle unregistered.

Garage address

The registered location where a heavy vehicle is normally kept; changes must be notified to the registration authority within the required period.

National Heavy Vehicle Regulator

The national body administering heavy vehicle registration, accreditation, and permits under the Heavy Vehicle National Law, operating in participating states including Tasmania.

Assessing Fitness to Drive

The national medical standards guideline used to assess whether commercial drivers meet vision, hearing, cardiovascular, and other health requirements for heavy vehicle licensing.

Chain of responsibility

The legal principle that parties in the heavy vehicle supply chain - schedulers, consignors, loaders, and drivers - share duty to prevent mass, dimension, loading, and fatigue breaches.

Load restraint standard

The requirement that loads withstand forces of 80 percent of load mass forward, 50 percent rearward, and 50 percent sideways, as set out in the National Load Restraint Guide.

General access mass limit

The maximum mass a heavy vehicle combination may operate at without a permit; a six-axle semi-trailer is limited to 42.5 tonnes GCM on general access routes.

B-double mass limit

A B-double combination may operate up to 62.5 tonnes GCM on approved routes, subject to axle group limits and network access conditions.

Standard fatigue hours

Under Heavy Vehicle National Law, a driver using standard hours may work a maximum of 12 hours in any 24-hour period with required minimum rest breaks.

Vehicle dimension limits

General access heavy vehicles must not exceed 2.5 metres wide, 4.3 metres high, and 19 metres long; larger dimensions require an oversize permit.

Tyre tread minimum

Heavy vehicle tyres must have a minimum tread depth of 1.5 millimetres across the tread width, and tyres must be free of defects and correctly inflated.

Four-second gap

The recommended minimum following distance for heavy vehicles in good conditions, increased to six or more seconds in rain, at night, or when fully laden.

Speed limiter requirement

Heavy trucks and buses are required to be fitted with a speed limiter set to a maximum of 100 km/h, and must not exceed that limit even where posted limits are higher.

Level crossing rule

Heavy vehicles must stop at a stop sign or give way at a give-way sign at railway crossings; buses carrying passengers must stop at every level crossing.

Rear overhang flag

Loads projecting beyond the rear of a heavy vehicle must be marked with a visible flag or warning device so following drivers can see the overhang.

Roundabout lane use

Heavy vehicles may need both lanes in a roundabout; drivers must indicate left to exit and give way to vehicles already circulating in the roundabout.

Heavy vehicle parking rule

Heavy vehicles must not park on footpaths, nature strips, or within 20 metres of an intersection unless signage permits, to preserve sight lines and pedestrian access.

Reportable crash

Any crash involving injury, death, or property damage above the reportable threshold must be reported to police, and vehicle defects must be reported to the operator.

Medical certificate validity

A commercial driver medical certificate is generally valid for 12 months, or a shorter period if a health condition requires monitoring, and must be renewed at licence renewal.

Registration refund

A pro-rata refund of unused registration may be claimed on surrender of number plates, calculated from the date the plates are returned with a cancellation form.

Address change notification

Registered operators must notify the registration authority within 14 days of changing their garage address or postal address for a heavy vehicle.

Replacement document fee

A fee applies to replace a lost or stolen heavy vehicle licence or registration certificate, and a statutory declaration is usually required.

Class 1 permit

A permit category for oversize or overmass vehicles such as cranes and agricultural machines, specifying approved routes, travel times, and escort requirements.

Class 2 permit

A permit category covering B-doubles and road trains operating on approved networks, allowing combinations that exceed general access mass or dimension limits.

Pilot vehicle requirement

Oversize loads exceeding specified width or length thresholds must be preceded or followed by pilot vehicles warning other traffic; very wide loads also require police escort.

Roadworks speed limit

Reduced speed limits posted in roadworks zones are legally enforceable, and heavy vehicles may face additional lane or route restrictions during construction works.

Bridge mass restriction

Posted mass limits on bridges and culverts must be observed; operators should check the bridge restriction list before planning a heavy vehicle route.
