Department of State GrowthTransport

Speed Limit Reviews

Speed limits are reviewed for a variety of reasons including requests from local council, Police or the community, due to development, or changing road environments.

Reviews are the responsibility of the relevant road manager and for State Roads that sits with the Department of State Growth. Speed limits can only be changed by the Commissioner for Transport following a speed limit change application from the relevant road manager.

Speed limit changes

Huon Highway, Vinces Saddle/ Sandfly

What is the decision?

Vinces Saddle

The Department of State Growth is reducing the speed limit from 100 km/h to 80 km/h on the Huon Highway at Vinces Saddle for about 4.1 kilometres, in both directions, from the cemetery at Lower Longley travelling towards Hobart. This will add approximately half a minute to travel time through this section.

Sandfly intersection

The Department of State Growth did not apply to have the speed reduced at the intersection.

What are the reasons for this decision?

Vinces Saddle

There is a clear case for reducing the speed limit at Vinces Saddle on the Huon Highway for safety reasons. This section of the highway is steep, winding and has one of the highest crash rates on the entire State road network.There have been 81 reported crashes on this section of road in the last five years. The most common type of crash is loss-of-control involving a single vehicle, which indicates that motorists are travelling too fast. The crash history shows vehicle crashes are evenly distributed across the year and at different times of day, with no apparent links to particular weather conditions.

Sandfly intersection

A number of factors informed the Department’s decision, including the relevant Australian road engineering standards, feedback from road users and the Department’s commitment to upgrade the intersection.

Consultation Findings

The full Community Consultation Feedback Report is available here. In total, 296 people submitted feedback. At Vinces Saddle, 78 per cent of submissions expressed opposition to the speed limit change and 22 per cent supported it. At Sandfly Road intersection, 64 per cent of submissions opposed the speed limit and 36 per cent supported it.

Midland Highway, Southern Outlet Launceston

What is the decision?

The Department of State Growth is reducing the speed limit on the Launceston Southern Outlet from 110 km/h to 90 km/h for about 2.2 kilometres from the Bass Highway Interchange and Howick Street, travelling in both directions. The speed reduction will add an extra 16 seconds to road users travel time

What are the reasons for this decision?

A fatality on this section of highway in November 2018 initiated a review of the speed limit. Key stakeholders and road users were consulted on the speed review in May 2019, the Consultation and Findings Report is available here (PDF, 566.95 KB). Mixed opinions are expected when asking road users about speed limit reductions, and most road users opposed the speed reduction.

This section of the highway carries about 28 000 vehicles a day and is on a very steep hill. Since 2013 there have been 137 reported crashes on this section of Highway. Traffic flow is disrupted by slow moving trucks and merging vehicles. There is a high nose-to-tail crash rate on the Southern Outlet indicating motorists are travelling too fast.  A speed reduction will improve safety for all road users, and have the additional benefit of reducing crash related congestion on the Southern Outlet.

Variable speed signs will not maximise improved safety benefits for all road users. Although crashes on this section of highway are more common during peak hours they happen at all times.

Research indicates that even small reductions of 10 km/h in travelling speeds can lead to 25 per cent reductions in serious casualties.

Huon Highway, Dover

What is the decision?

The speed limit on the Huon Highway at Dover is being reduced from 80 km/h to 60 km/h for 1.83 kilometres from Francistown Road travelling south.

What are the reasons for this decision?

The Department of State Growth investigated the speed limit on the Huon Highway at Dover following a request from a local resident. A reduction was justified and approved by the Commissioner for Transport according to national standards.

Research shows even small reductions of 10 km/h in travelling speeds can lead to a 25 percent reduction in serious casualties.

Please observe new speed signs, which will be installed in November 2019.

Huon Highway, south of Huonville

What is the decision?

The speed limit on the Huon Highway to the south of Huonville is being reduced from 100 km/h to 80 km/h for 1.8 kilometres.

What are the reasons for this decision?

The Department of State Growth investigated the speed limit on the Huon Highway to the south of Huonville following a request from a local resident and the Huon Valley Council. A reduction was justified according to national standards.

Research shows even small reductions of 10 km/h in travelling speeds can lead to a 25 percent reduction in serious casualties.

Please observe new speed signs, which will be installed by the end of September 2019.

Grasstree Hill Road - Richmond

What is the decision?

The speed limit on Grasstree Hill Road is being reduced from 100 km/h to 80 km/h for about 2 kilometres, from the Malcolms Hut Road and Back Tea Tree Road junctions travelling east to the existing 60 km/h speed limit.

What are the reasons for this decision?

The Department of State Growth investigated the current speed limit of Grasstree Hill Road following a request from a local community member.

Reducing the speed for this additional section of Grasstree Hill Road will provide a sensible balance between efficient traffic flow for through traffic and local amenity for vehicles turning at junctions and accesses.

Research shows even small reductions of 10 km/h in travelling speeds can lead to a 25 percent reduction in serious casualties.

Please observe new speed signs, including advance warning signs indicating the changed limit, which will be installed along Grasstree Hill Road.

Wilmot Street, Port Sorell

What is the decision?

The  40 km/h school zone at Wilmot Street, Port Sorell has been reduced from 670 metres to around 390 metres.

What are the reasons for this decision?

The Department of State Growth investigated the current 40 km/h school zone following concerns expressed about driver behaviour in the 40 km/h school zone and at the children’s crossing at Wilmot Street.

Reducing the length of the existing school zone is predicted to have a positive impact on driver behaviour. The shorter zone will focus on the children’s crossing. Drivers turning out of side roads (Kermode Street and Blackwood Court) will pass electronic 40 km/h school zone signs before reaching the children’s crossing.

Please observe the new signs which will be installed on Wilmot Street in the coming weeks.

Channel Highway, Deep Bay

What is the decision?

In May, the 80 km/h zone on the Channel Highway at Deep Bay south of Chuter Street to south of Cliffords Road was reduced to 60 km/h for 1.3 kilometres.

What are the reasons for this decision?

Research shows even small reductions of 10 km/h in travelling speeds can lead to a 25 percent reduction in serious casualties.

The Channel Highway at Deep Bay has growing residential characteristics including increased vehicle and pedestrian activities, the reduced speed limit will improve road safety for all road users.

South Arm Road, Lauderdale

What is the decision?

By mid-June 2019, the 80 km/h zone on South Arm Road between Oakdowns roundabout and Acton Road will be reduced to 70 km/h.

There will also be a 40km/h variable speed zone for around 600 metres along South Arm Road, between Acton Road and Ringwood Road for southbound traffic. The variable speed limit will operate at the beginning and end of the school day.

What are the reasons for this decision?

The speed limit reduction from 80 km/hr to 70 km/hr will provide a safer approach to the intersection of South Arm Road and Acton Road, and will also be consistent with the speed limit in the adjoining section of South Arm Road that runs through Lauderdale, alongside Ralphs Bay.

The introduction of a 40km/hr variable school speed zone will improve safety for school students using the footpath on their way to and from school.

Updated 15 May 2019

Claude Road, Claude

What is the decision?

At the end of April 2019, the 100 km/h zone on Claude Road between the end of the current 80 km/h zone and Dasher River Bridge will be reduced to 80 km/h for 600 metres.

What are the reasons for this decision?

Research shows even small reductions of 10 km/h in travelling speeds can lead to a 25 percent reduction in serious casualties.

Reducing the speed for this additional section of Claude Road will improve road safety for all road users, including several local adjacent properties and a junction connecting to a public cemetery.

Please pay attention to new speed limit signs, including advance warning signs with the changed limit, which will be installed along Claude Road at the end of April 2019.

What’s considered when reviewing a speed limit?

A number of factors are taken into consideration when a review is carried out on an existing speed limit, including:

  • Safety concerns
  • Crash history
  • Condition of the road
  • What the road is used for
  • Traffic volumes
  • Presence of vulnerable road users, such as cyclists and pedestrians
  • Number of accesses and intersections
  • Compliance with AustRoads and engineering guidelines.

We may also consult with stakeholders such as police, local councils and the community to determine if a speed limit change is supported.

How do I request a speed limit review?
