Before the start of an IBA ride, you also want to have proof that your ride is about to start. This can be done by using the Witness document with a name and details of the witness. At the start and also at the end of your ride.

But because nowadays we can also use a photo camera, where you can see yourself with your engine and the starting position of the odo-meter with your fuel receipt. In that case, the Witness-document does not have to be completed and send in.
