How many ULEZ-related PCNs were issued within the first month of operation of the expanded zone, and how do these figures compare with the same period for the last three years?
As I said in my response to 2021/4885, Transport for London (TfL) used its discretion to issue warning notices rather than Penalty Charge Notices (PCNs) for the first month after the launch of the ULEZ expansion when the zone expanded to 18 times its original size.
Around 124,000 warning notices were issued to non-compliant vehicles seen using the zone in the first four weeks after expansion, between 25 October and 22 November 2021. TfL issued 22,389 PCNs for non-compliance in the central ULEZ zone during the same period in 2020, and 48,705 PCNs during the same period in 2019, No ULEZ PCNs were issued in October 2018 as this was before the scheme launched.
Transport for London publish a detailed breakdown of compliance, payments received and fixed penalty notices issued each quarter in a series of Ultra Low Emission Zone factsheets, which can be found online here: https://tfl.gov.uk/corporate/publications-and-reports/ultra-low-emission-zone.
