Warnings are given 10 seconds before you will reach the speed camera. You are warned in several ways:
Tip: In the VIO app map, you can select a speed camera symbol on the map bar to see the type of camera, the maximum speed and also the length of an average speed check area.
When you are driving in an average speed check area or a speed enforcement 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).
