ZTL Helper is the tool to help you understand when you are getting close to an active Limited Traffic Zone in Italy and avoid it.
A monitoring system based on geofencing can send you notifications when getting close to working gates.
To help you while driving, you can use vocal commands to reposition the map and activate or deactivate monitoring.
Consult the list on LTZ of your city to discover days and timetables of the gates.
You can add permissions of access to a LTZ for your vehicles authorised to navigate through it so to not receiving alerts for that particular LTZ.
Currently the list of LTZ supported includes the ones in Campania. In future updates the support will be extended to other Italian cities.
