The Road User Charge (RUC) applies to each litre of fuel, such as diesel, used by heavy vehicles such as buses, coaches and trucks on public roads.
Ministers agreed to an annual 6 per cent increase to heavy vehicle charges each year between 2023-24 and 2025-26. The current RUC is 28.8 cents per litre.
The RUC is set out in the Fuel Tax Act 2006.
