Car tax rules for a 2016 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
- Petrol cars first registered from 2006 usually meet Euro 4, the petrol standard for the London ULEZ, so they usually do not pay the daily charge.
- Diesel cars first registered from September 2015 usually meet Euro 6, the diesel standard for the London ULEZ, so they usually do not pay the daily charge.
- 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
