This is the Tasmanian road network that has been assessed for Performance Base Standards (PBS) Level 1 Heavy Vehicles. The accessibility on the roads and bridges has been divided into 3 categories: Approved, Conditionally Approved and Restricted. Four PBS classification levels exist (1 to 4), with the PBS 1 classification describing heavy vehicle combinations which are up to 20 metres in length and complying with PBS 1 performance criteria. The PBS scheme is administered by the National Heavy Vehicle Regulator (NHVR) and provides the freight industry opportunity to innovate with vehicle design to improve productivity and achieve safer performance while minimising impact on the environment and road infrastructure. PBS vehicles are designed, built and assessed against stringent safety and infrastructure standards to ensure they are safe and fit for use on road networks that are appropriate for their level of performance.

This dataset indicates parts of the State road network that are subject to declarations of Limited Access. The information used to define this has been obtained from current proclamations of Limited Access made in accordance with Part IVA section 52A of the Roads and Jetties Act 1935. The main purpose of declaring a State road to be a Limited Access road is to enhance road safety and efficiency. A property that has a common boundary with a Limited Access roads may have no direct access to that road as a result of the declaration, or, if it has an existing direct access, use of that access may be subject to a conditional licence. Provision of a conditional licence is usual practice for private accesses and are granted in accordance with provisions of the Act. Property access may also be gained to a Limited Access road via a proclaimed place of access, generally a public road, use of which is not subject to conditions of use under the Act.

Control of Access identifies the sections of state roads where the access to and from adjacent land and properties is controlled by Main Roads Western Australia. These road sections have statutory declared Control of Access, which revokes the general right of adjoining land to have direct vehicle and pedestrian access to these roads. This layer shows Control of Access on all State Roads. All State Road ramps have declared Control of Access and may not be shown in this layer.Note that you are accessing this data pursuant to a Creative Commons (Attribution) Licence which has a disclaimer of warranties and limitation of liability.
