How do I reinstate my license after a DUI?

The sequence matters, because the steps have dependencies.

First the revocation or suspension period has to run, or you have to reach the point where you're eligible for reinstatement or hardship. Then DUI school has to be complete, including any evaluation and any treatment it recommended. Then proof of insurance — Florida requires a specific filing for drivers reinstating after a DUI, held for a period of years, and it's more expensive than ordinary coverage.

Then the fees, paid at a tax collector's office or service center.

Where an interlock is required, it has to be installed before reinstatement, not after.

The common failure isn't any single step. It's discovering months in that the evaluation recommended treatment nobody completed, or that the insurance filing was never made. Getting the list at the beginning is worth more than working through it in order.
