Drivers who enter the Clean Air Zone in Bristol when it begins on Monday won't automatically receive a fine - they will have six days to pay the charge and avoid getting a penalty charge notice.
Bristol City Council has revealed that the scheme is being set up to allow for drivers who unexpectedly find themselves driving into the Clean Air Zone, those who entered it without realising, or those who didn't know about the scheme before they set off on their journey.
It means that people can retrospectively pay the charge after they have made their journey - and as long as they pay the charge quickly, they won't get a fine letter through the post. But, unlike the system in London, there is no ability in Bristol for drivers to set up their registration number and bank details to automatically pay the charges whenever they have incurred them.
