Now that the Clean Air Zone is up and running, we want to find out if it will change the way you drive in Bristol. So take part in our poll and let us know.
Bristol City Council estimates that about three in 10 vehicles on the city's roads will be affected by the charges, which cost £9 a day for smaller vehicles and £100 a day for larger vehicles.
That still equals a large number - a trial of the CAZ cameras in September tested out the systems sending out letters to every motorist whose vehicle would be liable for the charge once the scheme went live. In that time, almost 100,000 motorists received letters. The council predicts the figure could be even higher, with an estimated 75,000 vehicles affected per day.
