Speed limits are set by the Commissioner for Transport and are determined in accordance with Australian Standards and Austroads guidelines.
Speed limits are set to reflect varying road environments, vehicle types and community needs such as safety and convenience.
In Tasmania, the default speed limits are 50km/h for urban roads and 80km/h for rural gravel road or 100km/h for rural sealed roads.
The Department of State Growth monitors the road network and reviews speed limits when necessary.
Any changes to Tasmanian speed limits are listed here, along with the reasons for the decisions.
The public is also able to request a review of a speed limit on a State road at any time by emailing info@stategrowth.tas.gov.au.
