The TAG is a small electronic device. It is fixed to the inside of the windscreen of your vehicle by our staff.
Our TAG is activated and deactivated automatically when the tunnel is used. Microwaves are used to create a connection with your customer account when the toll station is passed and the tariff due is charged at the reduced amount. This process takes approx. 2 seconds. You do not need to stop in the toll station. You simply drive through slowly. When only 3 journeys are remaining, the TAG account is automatically credited by direct debit.
