Speed Adviser is a free driver's aid app developed by Transport for NSW that uses GPS technology to monitor your speed and location. The app alerts you with visual and audible warnings if you exceed the speed limit, helping to reduce speeding and ultimately save lives on NSW roads.

One of the key features of Speed Adviser is that it displays the speed limit for the road you're travelling on, including school zones and their operating hours. The app uses the latest speed zone data, ensuring you never have to guess the speed limit again.

Installing Speed Adviser is easy, and it can be downloaded from the Play Store app on your Android phone or via the Google Play website on your computer. The app will not download until it has been connected to a WiFi network, so be aware that it may cost more to download over a mobile phone network.

Speed Adviser also allows you to customize how you receive notifications for speed limit changes. You can choose to have the new limit spoken aloud in a male or female voice, hear a simple sound effect, or rely solely on the visual alert.

Overall, Speed Adviser is a must-have app for any driver in NSW who wants to stay safe and avoid speeding fines.
