Maryland Class A CDL applicants should study Maryland CDL Manual Section 6 for combination-vehicle knowledge: coupling and uncoupling, fifth wheel and kingpin checks, landing gear, air and electrical lines, glad hands, trailer brakes, trailer ABS, inspection, off-tracking, rollover risk, safe turns, backing, trailer skids, jackknife recovery, speed, and space management. Federal rules require at least 80% correct on each knowledge test, and failing the combination portion prevents Group A CLP/CDL issuance.

Maryland CDL Combination Study Tips from Top Performers

1Start with Maryland CDL Manual Section 6 and make a checklist from each subsection: safe driving, trailer air brakes, ABS, coupling, uncoupling, and inspection.
2Practice the coupling sequence until you can explain trailer height, fifth-wheel position, backing under, tug test, visual lock check, line connection, trailer air charging, brake testing, landing gear, and chocks in order.
3Memorize the difference between the emergency/supply line and service line, then drill glad hand seal, crossed-line, trailer air supply, and tractor protection valve scenarios.
4Study control risks as cause and effect: high or off-center cargo increases rollover risk, quick steering causes rearward amplification, off-tracking cuts trailer wheels inside, and locked trailer wheels can jackknife.
5Before testing, verify current Maryland MVA fees, documents, medical certification, ELDT status, and branch procedures on official MVA and FMCSA pages.

Frequently Asked Questions

Who needs the Maryland CDL Combination Vehicles test?

Drivers seeking Maryland Class A privileges for qualifying combination vehicles generally need the Combination Vehicles knowledge test, along with General Knowledge and any applicable Air Brake or endorsement tests. Federal Group A rules cover combinations with GCWR of 26,001 pounds or more when the towed unit is over 10,000 pounds GVWR.

What score do I need to pass?

49 CFR §383.135 requires at least 80% correct on each CDL knowledge test. The same rule says a driver who fails the combination-vehicle portion must not be issued a Group A CLP or CDL.

What topics are on the Maryland combination test?

Study Maryland CDL Manual Section 6: rollover risk, rearward amplification, off-tracking, wide turns, backing, trailer skids, jackknife recovery, trailer hand valve, tractor protection valve, service and emergency lines, glad hands, fifth wheel, kingpin, landing gear, coupling and uncoupling, and combination inspection.

How much does Maryland CDL testing cost?

Maryland MVA publishes CDL transaction fees rather than a separate Combination Vehicles-only test fee. The MVA fee page lists a $106 CDL learner’s permit, $64 CDL renewal or out-of-state conversion, and $20 CDL skills retest.

Does ELDT apply to Maryland Class A applicants?

FMCSA ELDT applies before skills testing for first-time Class A or Class B CDL applicants and Class B-to-Class A upgrades, unless an exception applies. Combination Vehicles is a knowledge test, but most first-time Class A applicants should verify ELDT completion before scheduling skills testing.
