Bristol's Clean Air Zone cameras will be switched on at exactly midnight as Sunday night becomes Monday morning, as overnight drivers of the most polluting vehicles will be the first to be liable to pay a charge.
The new era of traffic management in the centre of Bristol begins on Monday - and that means that the long-awaited Clean Air Zone regulations come into force from the very start of November 28 - in the first minute after the clock strikes 12.
Drivers using non-compliant vehicles - generally older diesels and petrol-powered cars and vans and larger lorries, buses, coaches and trucks - will be required to pay a charge of either £9 or £100 for bigger vehicles if they are driven into the Clean Air Zone, which stretches from the Brunel Way dual carriageway over the Cumberland Basin at the western end of the Floating Harbour, all the way either side of the river to Temple Meads and Newfoundland Way at the bottom of the M32 into the city centre.
