Roads Act 1993

A roads authority may regulate traffic on a public road by means of barriers or by means of notices conspicuously displayed on or adjacent to the public road.

The power conferred by this section may be exercised by TfNSW for any purpose but may not be exercised by any other roads authority otherwise than—

for the purpose of enabling the roads authority to exercise its functions under this Act with respect to the carrying out of road work or other work on a public road, or

for the purpose of protecting a public road from serious damage by vehicles or animals as a result of wet weather, or

for the purpose of protecting earth roads from damage caused by heavy vehicles or by animals, or

for the purpose of protecting members of the public from any hazards on the public road, or

for the purpose of protecting vehicles and other property on the public road from damage, or

for the purpose of enabling a public road to be used for an activity in respect of which a permit is in force under Division 4 of Part 9, or

for a purpose for which the roads authority is authorised or required, by or under this or any other Act or law, to regulate traffic.

A roads authority may not restrict the passage of heavy vehicles or animals along the roadway of an earth road unless clear side tracks have been provided for their passage.

A person—

must not, in wilful contravention of any such notice or in wilful disregard of any such barrier, pass along, or cause any vehicle or animal to pass along, a length of public road, and

must not damage, remove or otherwise interfere with a notice or barrier erected for the purposes of this section.

It is the duty of a roads authority by which a notice or barrier has been erected under this section to remove the notice or barrier if there is no longer any need to regulate traffic for the purpose for which the notice or barrier was erected.
