The interactive map shows HML-approved routes and restrictions as an overlay on top of Google maps. Roads and Maritime Services has no responsibility for, and does not guarantee the accuracy of, the underlying Google maps. Roads and Maritime strives to be accurate in showing the HML-approved routes and restrictions, however there may be errors and omissions caused by Google maps being incorrect or out of date. Roads and Maritime is not responsible for errors or omissions due to changes to the map by external organisations.
Travel conditions which apply to an approved route or area for a restricted access vehicle must be observed. For example, HML B-Doubles must still observe all travel restrictions on a Class 2 B-Double Notice. Further information regarding B-Double and Road Train travel restrictions is available.
