Roadsigns

The 1TMTA provides heavy vehicle operators with flexibility in loading certain heavy vehicle combinations. The 1TMTA allows increased mass on tri-axle groups so that they may be loaded by up to 1 tonne (t) above the normal tri-axle group 20t General Mass Limit (GML) provided any additional mass loaded onto each tri-axle group is offset onto other non-steer axle or axle groups.

Parking signs are rectangular, either vertical or horizontal, with the time permitted to park, for instance 2P for parking permitted for two hours, in green on a white background.

To aid traffic flow on freeways or motorways at peak times lanes can be dedicated to cars carrying three or more occupants.

The mass and length limits provided in this diagram are based on the limits set out in the Heavy Vehicle (Mass, Dimension and Loading) National Regulation (the MDL Regulation) and are provided for general guidance only. You may be eligible to operate heavier and/or bigger vehicles in certain circumstances as allowed under the MDL Regulation and notices and/or permit-based schemes.

Street signs and place names are the most stolen signs in Australia, usually because they have a common connection to something else in the community. Signs including ‘Monaro’ are some of the most stolen.

If there was an award for the most confusing road signs in Australia it world have to go to Melbourne’s so-called ‘HOOK TURNS’ at a number of intersections in the city CBD and require right turns to be made from the left lane so the flow of trams isn’t impeded through the intersection.

Speed advisory signs telling you of the maximum safe speed you can expect to negotiate a sign-posted curve are also commonly used.

In some situations turns are banned for safety and to facilitate traffic flow. They could be left turns, right turns, or U-turns.

Median strip or traffic island

The front articulation point to the rear of a semi-trailer may be up to 13.6 metres if the trailer is designed and constructed for the positive control of temperature through the use of refrigerated equipment. Also, the distance from the front articulation point to the rear overhang line of not more than 9.9 metres does not operate in a B-double or road train combination and otherwise complies dimensionally.

In some cases, where lanes are changed at particular times of the day, for instance in peak hours, overhead warningsigns are used. A red cross is used to tell you the lane is closed, a green arrow tells you it is open to traffic.

Applying an agreed adjustment to account for possible variations allows the measurement to be based on the highest degree of accuracy achievable at any time and provides fairness to the outcome of the measurement process. The measurement adjustment process also provides fairness to industry and legal certainty in considering enforcement action.

Road signs in Australia are a state responsibility, but they conform to national guidelines, so that are in effect the same right across the country.

The fixed school zone signs are often accompanied by flashing speed signs, with the speed limit in white inside a flashing red circle.

In some cases the parking limitations only apply for certain times on particular days, and that information will also be shown on the sign.

Livestock carriers- A trailer built to carry cattle, horses, pigs or sheep on two or more partly or completely overlapping decks must not have more than 12.5 metres of its length available to carry cattle, horses, pigs or sheep. In a B-double built to carry cattle, horses, pigs or sheep, the two semitrailers must not have more than 18.8 metres of their combined length available to carry cattle, horses, pigs or sheep. Note - the length available for the carriage of cattle, horses, pigs or sheep on a trailer is measured from the inside of the front wall or door of the trailer to the inside of the rear wall or door of the trailer, with any intervening partitions disregarded.

A ‘ONE WAY’ sign is square with the words ONE WAY and an arrow in the direction of the permitted traffic flow in black on a white background with a black border.

In some case the parking ban only applies on certain days and at certain times, and these will be spelt out on the sign.

The signs denoting a transit lane are white with the words Transit Lane in black above an indicator of the number of occupants needed before you can use the transit lane in white on a red background.

It is a rectangular sign with a ‘P’ in black inside a red circle with a diagonal red line through the ‘P’ on a white background. It also has an arrow indicating the area of the parking ban.

In some cases turns are only banned at certain times of the day. When that is the case the sign also has the times when the turn in banned.

Also included in the sign are the days and the time of day the transit lanes are used. It’s usually weekdays, either in the morning or afternoon.

The signs indicating a particular turn is banned are rectangular with a black arrow in the direction of the banned turn inside a red circle on a white background.

They are mostly yellow and black, but could be orange and black, or could be a red triangle if it’s an incident on the road.

Warning signs are also displayed at locations where traffic has to merge, say from three lanes to two, or two to one. The graphic will show an arrow/arrows continuing on where traffic is unaffected, and one coming to a dead end where you have to merge in to an adjacent lane.

These signs are rectangular with a white background and a red box in which the particular use of the zone is show in white.

To make a right turn at the intersections where HOOK TURNS are required you must drive into the intersection in the left lane indicating your intention to turn right and then come to a halt and wait until through traffic clears when you can safely complete the turn.

For a complete list of mass and dimension limits applicable to your circumstances, please refer to the MDL Regulation and/or relevant authorisations.

HOOK TURNS are indicated by a rectangular sign with a directional arrow and the words ‘RIGHT TURN FROM LEFT ONLY’ in black on a white background with a black border.

The articulation point to the rear of a semitrailer may be up to 13.2 metres if the trailer has a distance of not more than 9.5 metres from the front articulation point to the rear overhang line, does not operate in a B-double or road train combination and otherwise complies dimensionally.

Do not enter a street or road when you see a ‘NO ENTRY’ sign. It is most likely a one-way street and you would be going against the traffic flow.

Temporary warning signs are erected to warn drivers they are approaching a hazard that is currently requiring extra caution.

It is rectangular, with a white dash inside a red circle above the words ‘NO ENTRY’ in black on a white background with a black border.
