About the South Carolina Class B CDL exam simulator
The South Carolina Class B CDL practice test targets drivers headed for straight trucks, buses, and delivery rigs, and this 2026 simulator is a thorough class b cdl practice test. Whether you call it a class b license test, a class b license exam, or a cdl class b test, the written portion is the general knowledge exam every commercial applicant must pass.
A Class B license covers a single vehicle with a gross weight over 26,001 pounds, or such a vehicle towing a trailer under 10,000 pounds. Think dump trucks, box trucks, large buses, and garbage trucks. It differs from a Class A, which pulls heavy trailers, and a Class C, meant for smaller hazmat or 16-plus-passenger vehicles. All classes share the same 50-question test with an 80 percent passing score.
Class B work keeps South Carolina moving, from delivery fleets serving Greenville and Columbia to the buses and service trucks on local routes. The South Carolina Commercial Driver License Manual is the authority behind every question, so keep it handy. Drill this cdl class b test until you pass with room to spare, then set your exam date.
Every question traces back to the South Carolina CDL Manual - skim the right-of-way and signs chapters before your retake.
