With the cessation of height permit administration since 27 February 2006, owners and drivers of tall vehicles are responsible to verify their safe passage along the proposed travel route and engage auxiliary police escort if the overall height is more than 4.5 metres

The owner and driver must ensure that the tall vehicle does not proceed to or beyond any overhead structures or street furniture with little or no headroom unless verified safe to do so by qualified persons.
