How does the Electronic Toll System Work?

The system uses electronic devices, tags, fitted to vehicles to allow tolling without physical payment using cash or voucher. The tag is a small electronic device fitted on the inside of the vehicle windscreen which is read either by roadside equipment at the Bridge or by a handheld reader at the Ferry.

Tag users are required to set up a pre-paid account, (minimum £30 for a single car account) and each time a tolled crossing is made, the appropriate toll is deducted from the account and the transaction recorded.

Tags are supplied free of charge and tag users enjoy a 50% discounted toll.
