If you looked up a class b cdl practice test, a class b license test, a class b license exam, or simply the cdl class b test, this simulator prepares you for the written exam that comes first: 50 general knowledge questions with an 80 percent passing score.

A Class B license covers a single vehicle rated over 26,001 pounds, such as a straight truck, a large delivery vehicle, or a city bus, and it can tow a trailer under 10,000 pounds. Understanding the classes of cdl drivers license helps here: a Class A pulls a heavy trailer, while a Class C commercial driver's license handles smaller placarded-hazmat or 16-plus-passenger vehicles.

Idaho Class B drivers often move produce, dairy, and dump loads around the state's farm and construction hubs, so the Idaho Commercial Driver's License Manual stresses inspection and control. Work this Class B practice test until a passing score feels certain.
