Plans for a Clean Air Zone in Birmingham have been approved by the government.
Under the proposals, some drivers will now have to pay £8 a day to drive in the city, whilst HGV drivers face a £50 charge.
But who will be affected and when will it come into action? Here's everything you need to know.
Where is the Clean Air Zone?
The Clean Air Zone, or CAZ, covers all the roads within the A4540 Middleway Ring Road, but not the Middleway itself.
When does it come into effect?
The exact start date hasn't been confirmed yet, but it's expected to come into force in January 2020. The charge will then apply 24/7, 365 days a year.
How much will I have to pay?
Under the proposals, cars, taxis - including Hackney Carriages and Private Hire cars - and LGVs will pay £8 a day.
HGVs, coaches and buses will pay £50 a day.
You will only pay the charge once per day and there are some exemptions (more on this below).
Does the charge apply to newer cars?
Diesel cars older than a EURO 6 (manufactured before 2015) and petrol cars older than EURO 4 (made before 2006) will have to pay the charge.
What about if I live in the city centre?
There are some exemptions for people who live in the city centre or commute.
If you have lived in the city centre since before September 2018, you won't be charged for driving in the CAZ until January 2022. Birmingham City Council said they hope to be able to offer additional incentives, such as public transport tickets or money towards a replacement compliant vehicle.
If you commute into the CAZ and earn less than £30,000 a year, you won't have to pay the charge until January 2021. The Council hopes to offer similar incentives to the ones listed above.
Vehicles registered with disabled tax class will be exempt altogether and people visiting key hospitals, GP offices and care homes within the Clean Air Zone will be exempt from the charge for a year.
