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 limits currently under review

Huon Highway, Vinces Saddle/ Sandfly

The Department of State Growth is reviewing the speed limit along the Huon Highway from Vinces Saddle to past the Sandfly Road Intersection.

Vinces Saddle

The 4.1 km from the Vinces Saddle  cemetery travelling towards Hobart is hilly, windy and subject to inclement weather including ice and snow.

The review of the speed limit on this section was triggered by an extensive crash history over the last five years; one of the highest per-kilometre crash rates in the entire State Road Network. In this section of the highway, there have been 81 reported crashes in that period, with 67 crashes involving loss of control indicating that speed was a major factor. The crashes resulted in 4 serious injury, 22 minor injury, 20 first aid and 35 property damage.

The crashes were distributed throughout the year – 24 in spring (Sep-Nov), 17 in summer (Dec-Feb), 18 in autumn (Mar-May) and 22 in winter (Jun-Aug).  The review includes analysis against the Australian Standard for speed limit setting, taking into account a number of factors including the crash history.

Sandfly Road intersection and Huon Highway

During the consultation period for the Huon Highway and Sandfly Road Intersection Safety Upgrade project, 43% of responses identified the speed of vehicles on the highway as an important issue affecting the intersection.

In response to this, the Department is now consulting with the community about their views on the current speed limit at this location and whether reducing the speed limit for the additional 1.5 kilometre downhill section of the Highway, up to 300 metres past the Sandfly intersection, has merit. This section of road will also be assessed against the Australian Standard.

How will the Department use your feedback?

The outcome of these assessments will inform any application that may be made to the Commissioner for Transport for a reduction in the speed limit on these sections of road.  The Commissioner for Transport  is the legal authority for setting speed limits on all roads in Tasmania and will consider any recommendations in terms of compliance with Australian Standards, road characteristics and crash history.

Once the Commissioner for Transport has reviewed the speed limit change, the outcome will be published on this page.

The feedback period closed on Monday 30 September. You can view the feedback given during the initial feedback period here: Vinces Saddle Speed Limit Review – interactive map.

The feedback period was extended to the end of September, instead of 16 September as previously advertised, due to the high level of public interest in this review.

The Departments application to the Commissioner will not inform or replace the design process currently being undertaken for the Huon Highway and Sandfly Road Intersection Safety Upgrade.

Speed limit changes

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.

Updated 18 June 2019

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?
