Car tax rules for a 2005 car
- Cars first registered from 1 March 2001 to 31 March 2017 are taxed by CO2 emissions band, from band A (the lowest emissions) to band M. The band is set by the CO2 figure on the V5C logbook.
These are the rules, not the amount for a specific car. Car tax check
ULEZ and clean air zones
- Many petrol cars first registered from 2001 to 2005 already meet Euro 4, but not all of them. For a 2005 petrol car the Euro standard of that car decides.
- Hybrids follow the Euro standard of their petrol or diesel engine.
- The clean air zones in Birmingham and Bristol use the same Euro 4 petrol and Euro 6 diesel standards. The low emission zones in Scotland use them too, but enforce them with fines, not a daily charge.
The Euro standard of the car decides, not the year alone. ULEZ checker
