Who needs the Mississippi CDL Combination Vehicles test?

Drivers seeking Mississippi Class A privileges for qualifying combination vehicles need the Combination Vehicles knowledge test unless an official transfer, waiver, or exemption rule applies.

What score do I need to pass?

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

What topics are on the Mississippi combination test?

Study combination inspection, fifth wheel and kingpin coupling, trailer height, tug and visual checks, air and electrical lines, landing gear, trailer brake controls, off-tracking, rollover, safe turns, backing, trailer skids, jackknife recovery, and speed/space management.

How much does the Mississippi CDL combination test cost?

Mississippi publishes CLP/CDL transaction fees rather than a separate Combination Vehicles-only fee. The Driver Service Bureau fee page lists a $16 CDL Learners Permit valid 6 months and a $55 CDL 5 year License.

Where do I study official Mississippi material?

Use the Mississippi Driver Service Bureau CDL Manual PDF, especially Section 6 Combination Vehicles, and confirm current licensing logistics on the Driver Service Bureau CDL pages.

Mississippi Class A CDL applicants who want to drive combination vehicles must pass the Combination Vehicles knowledge material along with any other required CDL tests. Study Mississippi CDL Manual Section 6: fifth wheel and kingpin coupling, tug and visual checks, air/electric lines, landing gear, trailer brakes, off-tracking, rollover, backing, trailer skids, jackknife recovery, and safe speed and space management. Federal CDL rules require at least 80% correct on each knowledge test, and failing the combination portion blocks Group A CLP/CDL issuance.
