Drivers in Europe using Google Maps may have noticed a circled Z icon appearing in their route details. This symbol indicates that the route passes through a low-emission zone (LEZ), an area where older, more polluting vehicles face restrictions or fines. Google Maps introduced these alerts in 2021, initially covering zones in Germany, the Netherlands, France, Spain, and the UK. The icon has since evolved from a circled i to a capital Z, and Google plans to expand the alerts to over 1,000 zones across Europe by 2025.
The LEZs typically restrict or charge vehicles that do not meet emission standards. For example, Amsterdam’s LEZ may ban certain diesel cars or require a specific emissions sticker. Google Maps provides a link to the city’s official page for drivers to check if their vehicle qualifies. However, the app does not know the emissions class of the car, drivers must verify this themselves.
If the Z icon appears, drivers should plan ahead. They can check alternative routes, park outside the LEZ and use public transit, or confirm with rental companies if driving a rental car. Ignoring the alert could result in fines, so paying attention to this warning is crucial for avoiding penalties while navigating European cities.
