CLEAN AIR ZONES
A guide to navigating the Bristol CAZ
Driving into Bristol soon? Whether you live locally or are going to visit Bristol for the first time, you’re going to need to be aware of the new Bristol Clean Air Zone (CAZ) that went live on Monday, 28th November 2022. From this date, all drivers of non-compliant vehicles, including cars, will need to pay Bristol CAZ.
Mavigating a new CAZ is confusing. Don’t worry, we’ve made you a step-by-step guide detailing how to check if you’re exempt from Bristol CAZ or how to pay it in a matter of seconds.

Navigating the Bristol Clean Air Zone
Part 1: How will I know if I have driven into the CAZ?
Signs have already been put up across the city on the roads that lead into the Clean Air Zone. Some signs will indicate how far away the zone is, and others will let you know when the zone starts and ends. All signs will have a symbol with the letter D on it, indicating the class of the CAZ. View the image below for some examples of signs.

In addition to looking out for these signs while you’re driving, we also suggest you familiarise yourself with where the zone is in place.
The charging zone will extend across the city centre and harbourside, covering the area from Bristol Temple Meads to the A4176 Portway. The zone will operate 24/7, and like all other Clean Air Zones, the charge will only need to be paid once, even if you are entering the zone multiple times a day. You can see where it is in this Bristol CAZ map.

For more information about the boundary of the Bristol Clean Air Zone, read through our Bristol CAZ page here.
Part 2: How do I know if my vehicle needs to pay the Bristol Clean Air Zone charge?
Bristol is a Class D zone, meaning buses, coaches, taxis, private hire vehicles, heavy goods vehicles (HGVs), vans, minibuses and cars are all included in the charge, provided they don’t meet the minimum national emission standards.
To be exempt from the charge, your vehicle must meet the following emission standards:
- Petrol vehicle: Meet Euro 4 emission standards (typically 2006 onwards)
- Diesel vehicle: Meet Euro 6 emission standards (typically 2015 onwards)
- Hybrid vehicle: Meet the above standards depending on fuel type
- Have a fully electric vehicle
If you’re not sure whether your vehicle meets these requirements, don’t worry! Apart from making it easier for you to pay the charge, we’ve also created a Bristol Clean Air Zone vehicle checker!
All you need to do is download Caura (available on the Apple app store and Google play store) and enter your vehicle registration number into the app. You will see the CAZ charge in-app, telling you if your vehicle is exempt, or if you need to pay the charge. Click here to view a video tutorial on how to check exemption status using our Clean Air Zone vehicle checker.
If your vehicle is not exempt, Caura will let you know exactly how much you need to pay depending on your vehicle type, and you can go ahead and pay Bristol CAZ in a matter of just two taps. By doing it this way, you’ll never have to worry about getting a fine!
Part 3: How much is the Bristol Clean Air Zone charge, and how do I pay it?
The charge is £9 for cars, vans, taxis, minibuses, and light goods vehicles (LGVs) and £100 for HGVs, buses, and coaches. Motorcyclists are exempt from the charge.
If you need to pay for the Bristol Clean Air Zone, Caura is the quickest and simplest way to pay. Once you’ve entered your vehicle registration number into the app, tap ‘City Charges’ and select ‘Bristol CAZ’.
Using Caura, you can pay for yesterday’s, today’s or tomorrow’s travel – make sure you choose the right date and pay through either Apple pay, Google pay, or your preferred bank card.
No more faffing around with fiddly online forms and having to upload your personal details every single time you drive into the zone. Manage the CAZ with Caura instead.
