Concessions and exemptions are a matter for the Bridge Board. Exemptions are offered on a voluntary basis for certain disabled users (those on higher rate disability living allowance). Emergency services also receive exemption from tolls when on official duties.
In addition, on 28 July 2006, the Humber Bridge Board announced that it would discount toll charges for the local bus service (the X1) by 45 per cent. until the end of March 2008 to ensure it would continue to offer a service over the bridge. This concession remains in place and is subject to periodic review.
No estimation has been made by the Department for Transport for the amount of annual revenue forgone as a result of these exemptions.
