Car tax rules for a 1998 car
- Cars first registered before 1 March 2001 are taxed by engine size: one annual rate for engines up to 1,549cc and a higher rate above that.
These are the rules, not the amount for a specific car. Car tax check
ULEZ and clean air zones
- Diesel cars first registered before September 2015 usually do not meet Euro 6, so a 1998 diesel usually pays the ULEZ daily charge. A few models met Euro 6 early.
- 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
