Don’t worry. Since the OBU verifies where you drive in real-time to determine your precise location, a small delay is possible between what is registered by the device, and what you see on the OBU display. This is a sign that the OBU is determining your precise location by matching the GPS location with its internal map of the Belgian roads.

Note that the data shown on the OBU display is for information purposes (not binding). All the official billing documents are available on the Road User Portal.
