Florida CDL Exam Prep

Florida Department of Highway Safety and Motor Vehicles (FLHSMV) is the state agency responsible for issuing Commercial Driver's Licenses (CDL) in Florida. A CDL is required to legally operate commercial motor vehicles covered by 49 CFR Part 383, including large trucks, buses, and other vehicles above the federal weight and passenger thresholds. FLHSMV administers the knowledge and skills testing process, working within the framework set by the Federal Motor Carrier Safety Administration (FMCSA), while applying its own state-specific fees, scheduling, and administrative rules.

Every CDL applicant must first hold a Commercial Learner's Permit (CLP), pass the applicable knowledge test or tests, and wait at least the federal minimum 14 days after CLP issuance before attempting the skills test. Anyone applying for a first-time Class A or Class B CDL, upgrading from Class B to Class A, or applying for the P, S, or H endorsement for the first time must also complete Entry-Level Driver Training (ELDT) through a provider listed on the FMCSA Training Provider Registry before testing, a federal requirement in effect since February 7, 2022. Medical self-certification for all four federal categories is completed online through the MyDMV Portal. Two proofs of Florida residential address are required, and CDL cards carry a distinguishing header design tied to REAL ID rules.

Florida issues the three federal CDL classes defined in 49 CFR 383.91:

• Class A - Any combination of vehicles with a combined gross vehicle weight rating of 26,001 pounds or more, provided the vehicle(s) being towed have a gross vehicle weight rating of more than 10,000 pounds.
• Class B - A single vehicle with a gross vehicle weight rating of 26,001 pounds or more, or such a vehicle towing a unit with a gross vehicle weight rating of 10,000 pounds or less.
• Class C - A vehicle that does not meet the Class A or B definition but is designed to transport 16 or more passengers including the driver, or is used to transport hazardous materials requiring placards under 49 CFR 383.5.

Endorsements can be added to any class as needed: H (hazardous materials), N (tank vehicle), P (passenger), S (school bus), T (doubles/triples), and X (combined tank vehicle and hazmat). Florida offers endorsements H, N, P, S, T, and X, but does not permit triples combinations on Florida roads.

Florida's skills test is administered by state-certified Third Party Administrators and Testers rather than by FLHSMV staff directly; FLHSMV's role is regulatory oversight under 49 CFR 383 and Florida Statutes Chapter 322. Florida offers Classes A, B, and C with endorsements H, N, P, S, T, and X (triples combinations are not permitted on Florida roads). The exact question count for the general knowledge test was not independently confirmed from the current handbook text for this guide, so confirm the current format against the official CDL handbook before your test date.

FLHSMV does not clearly state the passing percentage on the page and manual text reviewed for this guide. The federal minimum passing score for CDL knowledge tests under 49 CFR 383.135(a)(1) is 80 percent, which is the standard most states apply. Confirm the current passing standard directly with FLHSMV or in the current manual before your test date.

Typical requirements to obtain a CDL in Florida include:

• Minimum age 18 for intrastate-only driving; minimum age 21 for interstate operation, hazmat (H or X endorsement), or passenger and school-bus (P or S) transport.
• A valid DOT medical certificate from an examiner listed on FMCSA's National Registry of Certified Medical Examiners.
• Entry-Level Driver Training (ELDT) through a provider on the FMCSA Training Provider Registry, required since February 7, 2022, for first-time Class A or B applicants, Class B-to-A upgraders, and first-time P, S, or H endorsement applicants (anyone who already held the relevant credential before that date is grandfathered).
• A Commercial Learner's Permit (CLP), held for a federal minimum of 14 days before the skills test may be scheduled.
• Passing the applicable knowledge test (general knowledge, plus air brakes and combination vehicles if applicable) and the skills test (vehicle inspection, basic controls, and road test).
• For the H or X hazmat endorsement, a TSA Security Threat Assessment (fingerprint-based background check) under 49 CFR Part 1572, in addition to the age-21 minimum.

Requirements can change. Always confirm current licensing rules with FLHSMV before applying.

FLHSMV publishes these CDL fees: an original or renewal CDL is a flat $75 (the fee does not vary by Class A, B, or C). Adding an endorsement is $7 flat. A knowledge retest is $10 and a skills retest is $20. A $6.25 tax-collector service fee may also apply. FLHSMV does not publish a separate CLP fee apart from the $75 CDL fee. Always confirm current fee amounts on the official FLHSMV fee page before paying.

A focused 6 to 8 week study plan works well for most Florida CDL candidates:

• Week 1-2: Learn the CDL class definitions (A, B, C), the endorsement letter codes (H, N, P, S, T, X), and the restriction codes (E, L, Z, K, O, M, N, V) from 49 CFR 383.153.
• Week 3-4: Study general knowledge topics: vehicle inspection, basic control, safe driving practices, and air brakes.
• Week 5: Focus on the combination vehicles section (coupling and uncoupling, doubles and triples basics) if you are pursuing a Class A license.
• Week 6: Review any endorsement-specific content you need (hazmat, tank vehicle, passenger, school bus) and confirm ELDT training provider requirements if this is your first Class A or B CDL.
• Week 7-8: Take full-length practice tests, review missed questions, and confirm the current knowledge and skills test format with FLHSMV before your test date.
