Sign Sizing
The size of the sign to be used is dependant on the traffic volume and the approach
speed. The A-D classification is used to describe sign size with A being the smallest and
D being the largest. The final design of sign size is to be determined by the works
supervisor after assessment of the road conditions, approach speeds and traffic volume.
The following is a guide for use:
• Size A signs – designed for roads with low traffic volumes and low approach
speeds;
• Size B signs- designed for use on roads with high traffic volumes and/or high
approach speeds;
• Size C signs – designed for use on freeways and other roads with approach
speeds greater than 100km/hr; and
• Size D signs – to be considered on roads where approach speeds are greater
than 100km/hr and the information to be communicated needs to be
emphasised or there is excessive lateral displacement of the sign.
Site conditions and constraints can influence the placement of signs around a proposed
works location. Hence, judgement will be required from on-site personnel to ensure the
signs are placed as close as possible to the spacing indicated on the TCP. Changes in
locations are to be documented with the details of the person making the changes.
