ADI stands for Advanced Driver Improvement. In Florida, your driver's license can be revoked or suspended if you accumulate too many points on your driving record. In order to have your driver's license reinstated, a Florida Court System may require an infringing driver to complete a Florida state approved ADI course. IDriveSafely is the most popular online ADI provider in the state. You can find more information on IDriveSafely and their 12 Hour Online Course here.
