Knowledge Test Class B
This license is required for driving a single vehicle with a GVWR of more than 26,001 pounds, and a trailer not to exceed 10,000 pounds gross vehicle weight rating, or a vehicle designed to transport 24 or more people (including the driver). To receive this license, applicants must pass a 50-question test. To pass, applicants must answer 40 questions correctly. Each question has two, three or four possible answer choices. Test questions come from the Minnesota Commercial Driver’s Manual. Questions come from chapters covering: Introduction, Driving Safely, Transporting Cargo Safely, Air Brakes (if applicable), Pre-Trip Vehicle Inspection Test, Basic Vehicle Control Skills Test and On-Road Driving.. Endorsements that may be used with a Class B CDL are: Hazardous materials, Tank, Passenger, HazMat and Tank, Air Brakes and School bus.
1. Placards should be used:
Placards must be placed on the outside of vehicles carrying hazardous materials. They identify the specific class or classes of materials being carried and warn others of relevant hazards.
2. Drivers often tailgate trucks in bad weather.
It is common for automobile drivers to follow too closely behind large trucks in bad weather, especially when it is difficult to see down the road. Safely respond to the tailgater instead of reacting by increasing your speed.
3. Which part of the truck is the air compressor connected to?
In an air brake system, the air compressor is connected to the engine through gears or a v-belt.
4. If driving so slowly that you could impede other drivers, you should:
If you must drive so slowly that you will impede the flow of traffic, you should turn on your four-way flashers to alert drivers behind you (as long as local laws allow the use of flashers).
5. Air brakes use ____ to function.
The brakes in an air brake system use compressed air to function properly.
6. Which of the following can help you determine when to upshift?
There are two indicators that determine when you need to shift into a higher gear. One indicator is the engine speed (rpm). You should read your vehicle's manual to learn its rpm range and shift up when you reach the top of that range. The other indicator is road speed (mph). You should learn which speeds each gear can accommodate, then keep an eye on the speedometer and shift up as needed.
7. Convex mirrors:
Many large vehicles have curved, convex mirrors. Convex mirrors allow drivers to see a wider area than flat mirrors. However, they also make objects seem smaller and farther away than they really are.

To request a non-English version of the Class B CDL written test, you must contact the DPS Driver and Vehicle Services Division and indicate your language preference. The DPS will then provide you with study materials and schedule a test appointment at a location where your preferred language is available.
It's important to note that while the written test may be available in a non-English language, all other aspects of the CDL testing process (such as the skills test) will be conducted in English. Additionally, you may be required to demonstrate your ability to read and understand English road signs and other important information during the testing process.
To request accommodations, you will need to complete and submit a Request for Accommodation of Disability form, which is available on the DPS website. The form requires you to provide information about your disability, the type of accommodation you are requesting, and any supporting documentation that may be necessary.
Some examples of accommodations that may be available include extended time to complete the test, a separate testing room with reduced distractions, or the use of assistive technology such as a screen reader or magnifier.
Once your request is received, the DPS will review it and determine if the requested accommodations are appropriate and reasonable. You will be notified of the decision and provided with instructions on how to schedule your test with the approved accommodations.
It's important to note that requests for accommodations must be made in advance of the scheduled test date to provide sufficient time for review and approval.
