In May 2003, the ACT Government introduced a 50 km/h default speed limit. This speed limit became the standard and was applied to all roads within the urban areas of the ACT. Areas where alternative speed limits apply are signposted as such (40km/h, 60km/h, 80km/h, etc). Under this arrangement, the default speed limit of 50km/h would apply without the need for additional signage.
This policy covers the use of regulatory 50 km/h signs in the urban areas of ACT.
Roads ACT, as the asset manager will not support the individual installation of 50 km/h speed limit signage within the urban areas on roads that come under the existing 50 km/h default urban speed limit.
The only exceptions shall be when:
i. A speed zone greater than 50 km/h terminates on a section of the same continuing road (e.g. change in road classification), in which case a 50 km/h speed limit sign shall be installed for motorists leaving the higher speed limit section.
ii. A speed zone less than 50 km/h terminates on a section of the same continuing road (e.g. end of a 40 km/h school/group/local centre zone), in which case a 50 km/h speed limit sign shall be installed for motorists leaving the lower speed limit section.
iii. If a childcare centre exists in a speed zone greater than 50 km/h, in which case a 50 km/h speed limit sign shall be installed for motorists entering the reduced speed limit section.
iv. As part of a Local Area Traffic Management (LATM) scheme.
v. As part of a risk assessment, based on the Safe System Infrastructure Framework
Roads ACT will not support new 50 km/h Area signs (R4-10-50) and 50 km/h End Area signs (R4-11-50) for installation on urban roads within the ACT. Roads ACT will remove these signs in areas where they currently exist when the signs are no longer serviceable, without replacement.
