GPS systems that include ZTL areas

I would not trust it if there were. All you have to do is look for the sign, a red circle--sometimes there are even lights.
Will you have a companion? I navigate while husband drives, which can help, so as we get close to an old town, we start looking for parking. It is really not the horror show some make it out to be.

I have tried both Waze and Google Maps directions and I can tell you they don't even burp when you fly past the ZTL signs. There are Italian language websites which try to provide maps of the ZTLs of the different cities but the zones change w/o fanfare, and it's hard to utilize map info real time while driving. One such is https://www.accessibilitacentristorici.it/Default.cfm It promotes apps called Warning ZTL and ZTL Warning, but i haven't tried them. Your best bet is looking at websites with examples of the signage. I agree with valadelphia, it's not as hard as it sounds - you handle the equivalents of ZTLs while driving in your own country without even noticing.

That's what I thought. Just thinking the way technology works today, you never know unless you ask.

Thanks.
