Car tax and ULEZ for a 2006 car
A car first registered in the UK in 2006 was issued a 55 (January–February), 06 (March–August) or 56 (September–December) plate, unless it was registered in Northern Ireland (no age identifier) or has since moved to a private plate. An imported one is plated when first registered here, so its plate can be newer than its first-use year. 06 plates
A 2006 car is taxed by its CO2 emissions band (A to M), shown on the V5C logbook. [2] Car tax calculator for a 2006 car
For the London ULEZ, a 2006 petrol usually meets Euro 4, and a 2006 diesel usually does not meet Euro 6. The Euro standard of the car decides, not the year alone. [3] ULEZ checker
