If a vehicle doesn’t meet the required emission standards and is caught on camera driving in the Clean Air Zone, they must pay a Clean Air Zone daily charge.
Drivers won’t receive a reminder that they need to pay the charge. After they’ve driven through the zone, they’ll have 6 days to pay the charge. If the daily charge hasn’t been paid by this time, they’ll receive a Penalty Charge Notice.
We enforce Portsmouth’s Clean Air Zone using a system that records the registration plate of vehicles travelling within the Portsmouth Clean Air Zone. There are clear signs around the zone:
- when drivers are approaching the Clean Air Zone, there are blue warning signs with a cloud symbol – these are placed to give drivers time to take alternative routes if they want to avoid entering the CAZ
- when drivers are entering the Clean Air Zone, there are signs with a white background, a cloud symbol and the letter “B”
There are 55 cameras within the zone. View the map of the CAZ zone on the Cleaner Air Portsmouth website.
