About the Pennsylvania CDL Combination Exam
The Pennsylvania CDL Combination Vehicles Test is the knowledge test area for drivers seeking Class A commercial privileges for qualifying tractor-trailer and other combination vehicles. PennDOT directs applicants to the Pennsylvania Commercial Driver Manual, where Section 6 covers driving combinations safely, combination vehicle air brakes, coupling, uncoupling, and inspecting combination vehicles. FMCSA Part 383 supplies the federal Group A vehicle definition and the 80% minimum knowledge-test passing standard. The tested knowledge centers on fifth wheel and kingpin coupling, trailer height, high coupling, tug and visual checks, air and electrical lines, landing gear, trailer brakes, off-tracking, rollover prevention, safe turns, backing, trailer skids, jackknife recovery, speed, and space management.
Assessment
PennDOT-administered multiple-choice CDL knowledge testing for Class A combination applicants; Pennsylvania issues Knowledge Test Authorizations for requested CDL classes, endorsements, and restriction removals, and applicants study PennDOT Commercial Driver Manual Section 6 for combination-vehicle material.
Time Limit
PennDOT does not publish a separate time limit for the Combination Vehicles knowledge test.
