What is different in Florida
Florida in particular
Florida hands most of its CDL skills testing to a network of state certified private Third Party Administrators and Testers, a structure the department's own oversight unit exists specifically to keep honest and consistent statewide.
The written exams themselves are federal
Florida decides the permit rules, the fees and who runs the skills test, but the knowledge you are tested on comes from 49 CFR Part 383 and is the same in every state, which is why the 145 questions here work wherever you apply.
What changes in this state
Fees
$75.00 for an original or renewal commercial driver license, per the state fee schedule; a knowledge retest costs $10.00 and a skill retest costs $20.00
