Traffic rules

1. Low-emission zone

A low-emission zone (LEZ) is a specific area in a city or region where access by certain high-polluting vehicles is restricted or banned to reduce air pollution and improve air quality. Only vehicles that meet specific emission standards (usually related to CO₂, NOx, and particulate matter) are allowed to enter without a fine or fee. In many European cities like London, Paris, or Berlin, LEZs are marked with signs like: 'Low Emission Zone – Only Euro 6 Vehicles Allowed' Vehicles that don’t comply may be fined or required to pay an extra fee.

Restricted entry for older, polluting vehicles (e.g., diesel trucks, old cars).
Environmental criteria applied to vehicles based on their emission class (Euro standard).
Traffic signs at entry points to notify drivers.
Surveillance cameras used to monitor and fine non-compliant vehicles.
Sometimes, a fee is charged for non-compliant vehicles (also called a Congestion Charge Zone).
Some cities also have Ultra Low-Emission Zones (ULEZ) or Zero-Emission Zones for even stricter pollution control.
