Waze will tell you if you're going over the speed limit
The latest addition to Waze, the community-based traffic and navigation app, has everything to do with speed limits. Namely, the Google-owned app has added support for notifying you when you're going over the speed limit.
This new feature currently only works in Austria, Belgium, Brazil, Colombia, Czech Republic, El Salvador, France, Hungary, Italy, Latvia, Liechtenstein, the Netherlands, New Zealand, Sweden, Switzerland, Trinidad, Tobago, and Uruguay, but is apparently going to land in other places too - at some point in the future.
It works like this: when you go over the speed limit, a visual alert will appear on the Waze speedometer. It will stay there until your speed goes below the limit again.
You can choose when the alert appears - either when the limit is reached, or when you exceed the limit by 5, 10, or 15%. The alert sound is optional. The new functionality should be available soon in the Waze app for Android and iOS.
