Regulatory signs inform road users of traffic laws or regulations which it would be an offence to disregard.

These signs indicate the application of legal requirements to locations or situations where the requirements may not otherwise be apparent and to which the road users’ attention should be particularly drawn.

Included in this classification are those signs which indicate the end or termination of a legal restriction imposed by a preceding regulatory sign. An example is the END LOAD LIMIT sign (R6-5)

The sub-classifications and the prefix and series number relevant to each are as follows:

R1 – Movement Series
R2 – Direction Series
R3 – Pedestrian Series
R4 – Speed Series
R5 – Parking Series
R6 – Miscellaneous Series
R7 – Exclusive-use Lane Series
R8 – Bicycle / Pedestrian Series
R9 – Supplementary Plates for General Use Series
