The Minnesota Combination Vehicles Knowledge Test includes 20 multiple-choice questions, covering critical topics such as safe operation of combination vehicles, air brakes and their use in tractor-trailers, preventing trailer skids and jackknives, coupling and uncoupling procedures, and inspection and maintenance requirements.
Passing this test, with its substantial amount of material, is one of several steps required to obtain a Class A Commercial Driver’s License (CDL). This particular class allows you to operate tractor-trailers or other large combination vehicles with a Gross Combination Weight Rating (GCWR) over 26,001 pounds, where the towed unit exceeds 10,000 pounds (Minnesota CDL Manual, Part A).
In addition to passing the CDL Combination Vehicles Test, you must also complete Entry-Level Driver Training (ELDT) through an FMCSA-approved training provider listed on the Training Provider Registry (TPR), pass the General CDL Knowledge Test, obtain a Commercial Learner’s Permit (CLP) and hold it for a minimum of 14 days, then pass the DVS Skills Test.
