The traffic ban imposed last Saturday has now been lifted, and heavily polluting vehicles (petrol and diesel vehicles with Euro 0, 1 and 2 engines with no anti-particle filters, two-stroke motorcycles and scooters with Euro 0 and 1 engines) may circulate again from Wednesday 8 November until 07.30 and after 19.30 Monday-Friday and all day at weekends.
