Dimension requirements

From 1 August 2013, changes to the Road Transport (Vehicle Registration) Regulation 2007 came into effect which allows Roads and Maritime Services to suspend heavy vehicle registration for up to three months where a dimension requirement offence has been committed.

The changes were introduced to provide protection to assets and infrastructure, improve traffic flow along major road corridors and further improve road safety for all road users.

What is a dimension requirement offence?

A dimension requirement offence is where a Clearance, Low Clearance, Load Limit or No Trucks sign on a NSW road, tunnel or bridge has been disobeyed.

If a heavy vehicle is detected committing a dimension requirement offence in NSW, Roads and Maritime may suspend vehicle registration for up to three months under the Road Transport (Vehicle Registration) Regulation 2007.

Which parts of the NSW road network does this apply to?

It applies to all NSW roads, tunnels or bridges where a dimension sign applies.

Dimension requirement restrictions are in place to protect important road assets in NSW. For example, over-dimension heavy vehicles that attempt to use major Sydney motorways (Sydney Harbour Tunnel, Eastern Distributor, M5 East, Lane Cove Tunnel and Cross City Tunnel) can cause significant structural damage to tunnels and cause damage to tunnel support infrastructure such as lighting, communications and fire systems.

Damaged and destroyed infrastructure can have a huge impact on the safety of other drivers and the public. When heavy vehicles get stuck in a tunnel or on a bridge, it causes delays for other motorists, and can significantly affect traffic flow.

Who does this apply to?

The new penalties apply for drivers and registered operators of NSW registered heavy vehicles that disobey dimension requirement signs.

Roads and Maritime may also suspend the visiting privileges of interstate heavy vehicles or Federal Interstate Registration Scheme (FIRS) vehicles that have committed an offence for up to three months.
