First and foremost, what is ULEZ?
ULEZ stands for Ultra Low Emission Zone. It is an initiative implemented by the government to reduce air pollution and improve air quality in the cities. Under the ULEZ scheme, vehicles entering or driving within the zone need to meet specific emission standards to avoid paying a daily charge. The emission standards are based on the vehicle’s exhaust emissions of nitrogen oxides and vehicles that do not meet the required standards must pay a daily fee to enter the ULEZ.
