1. Radio service
A radio service is a radio broadcast that provides drivers with traffic information such as congestion, road closures, accidents, weather conditions or other events affecting a journey. Roadside signs may indicate a particular radio station and frequency where traffic information is available.
Drivers can tune to the indicated frequency to receive local traffic information while travelling through the area. The service is informational and does not replace traffic signs, signals or instructions from authorised persons.
