How do I get my license back after it was suspended for not renewing my car inspection?

Was your license suspended right away or after a certain period? Anyway, you first need to get your car's inspection sorted out (have a mechanic do it and register it), then show up at the Prefecture or apply online through the motorist portal with the inspection documentation. Once you've done all that, your license gets returned to you, usually within a few days. It depends a bit on how the process went in your specific case, but basically it's just a matter of getting your car compliant.

An expired inspection is one of the most common reasons for suspension, unfortunately! The key thing is that you need to get it done right away by a mechanic and then register it in the system (you can do it directly online on the motorist portal or at a Motorizzazione office). Once your car is up to code, you submit everything to the Prefettura along with your license reinstatement request - they'll check that there aren't any other pending violations and they'll give it back to you.
