Front fog lights are designed to better illuminate the road in fog, rainstorms, dust clouds and mountain snowfall. They can be recognised by the low, narrow vertical pattern (and wide lateral spread) of light emitted.
Road Rule 217 states that drivers must not use front or rear fog lights unless driving in fog or other hazardous weather conditions that cause reduced visibility. They must be switched on separate from the main beam (high beam) and dipped beam (passing) headlights.
Fog lights should only be used in hazardous weather conditions.
Drivers should familiarise themselves with the dashboard warning symbols so that they do not inadvertently switch these lights on.
Use of fog lights when not required can result in a $185 Fine.
