The tolls on the Severn Crossings are amended each year in accordance with the rules set out in the Severn Bridges Act 1992. Every year the tolls are calculated from the September Retail Prices Index figure and then rounded to the nearest 10p. The toll levels from 1 January 2014 will be: Category 1: Cars and motor caravans—£6.40 (£6.20 in 2012) Category 2: Small goods vehicles and small buses—£12.80 (£12.40 in 2012) Category 3: Heavy goods vehicles and buses—£19.20 (£18.60 in 2012) The tolls levels will be confirmed in an Order made by the Secretary of State in December.
