Warnings are given 10 seconds before you reach a danger zone or risk zone. You are warned in several ways:
Tip: In the VIO app map, you can select a danger zone symbol on the map bar to see the zone information.
When you are driving in a zone, the speed camera warning screen is minimised to the right side of the screen 5 seconds after the warning is shown. To show the warning again in the full screen, tap the minimised warning area. (Only available in the VIO app for Android).
