What is different in Maryland

Maryland in particular

Maryland keeps the entire CDL exam process in house rather than farming the skills test out to private testers, and bundles the permit fee, the CDLIS check and the first road test attempt into one $90 charge instead of billing them apart.

The written exams themselves are federal

Maryland 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.
