A traffic bylaw is used to regulate a wide range of activities that take place on road reserve and parking areas within Wellington City. This is to protect, promote and maintain public health and safety and protect the public from nuisance and to minimise the potential for offensive behaviour preventing the wellbeing and enjoyment of the public using the road network and parking areas in the City.

The traffic bylaw sets the requirements for parking and the movement of traffic on any road or parking area owned or managed by Wellington City Council.
