No. It’s a minimum fuel efficiency standard that petrol cars registered after 2006 were legally required to meet. So it is a very lax standard in reality, and only removes the worst vehicles from the roads.
That’s what I’m saying / the congestion area is only for post 2006 vehicles.
The area is for all vehicles, and most petrol vehicles registered before 2006 must pay to enter it.
This isn't a congestion area, it's a low emission area. Vehicles before 2006 probably don't meet the emission standards and thus have to pay the premium. Cars after 2007 probably do meet the standards and thus don't have to pay the premium.
From the article: "It means only cars that meet strict emission requirements will be allowed to enter London areas without incurring a ULEZ charge: Euro 4 engine compliance for petrol cars (which includes any cars registered after 1 January 2006) and Euro 6 (after 1 January 2016) for diesel."
Oddly enough - one of my cars is a 2007 4.5 litre petrol engined… which is ULEZ compliant!
Surely a vehicle like mine is the one that should be taxed!
