What does the term "ZTL" signify on a road sign?

The term "ZTL" stands for "Zona a Traffico Limitato," which translates to "Limited Traffic Zone." This designation is commonly used in urban areas, particularly in Italy, to indicate regions where vehicle access is restricted or limited to reduce congestion and pollution, enhance pedestrian safety, and promote a better quality of life in busy city centers.

Vehicles may be restricted from entering these zones during certain hours or may require special permits for access. Understanding the significance of ZTL helps drivers comply with local traffic regulations and avoid potential fines or penalties associated with unauthorized entry into these restricted areas.

While other choices mention concepts like tolls or parking permits, they do not encapsulate the specific regulation meant by the ZTL designation, which primarily concerns the restriction of vehicle traffic in designated urban areas.
