With Drive One, you warn others about speed controls and other dangers in traffic with the two buttons on the device.

How you warn others

The top button showing a camera is used to warn about speed traps, and the lower button (warning sign) is used to warn about other dangers on the road:

How you confirm a warning

These two buttons are also used to confirm warnings from other users. E.g. if you are warned about a speed trap, an accident or something else on the road, then click on the corresponding button if you can confirm the warning. If you can't confirm it, you can just ignore the warning.

Through confirmations from users, we know that a warning is still relevant, and therefore it will be kept active for longer.

You can see more about the different types of warnings here.
