2. A Vermont CDL holder is not operating a commercial vehicle at present but wants to keep the license. Which category may this driver certify under, and what exception does the manual note?
Correct answer: Excepted Interstate (EI); it does not apply to the School Bus Endorsement
A driver who is not currently operating a CMV may certify as Excepted Interstate (EI), but a footnote says this does not apply to the School Bus Endorsement. On returning to commercial driving, the driver must update the certification and supply a valid DOT Medical Card.

4. A Vermont driver self-certifies as Non-Excepted Intrastate (NA). Which medical document does the manual say this driver must provide?
Correct answer: A "Vermont Only" Medical Examiner's Certificate that is current

6. A Vermont permit holder is training in a bus designed to carry more than 15 passengers. Where does the manual say the accompanying CDL holder may sit?
Correct answer: Right behind the driver, or in the first row back from the driver's seat
In most vehicles the CDL holder sits beside the permit holder. In a vehicle built for more than 15 passengers, a seat straight behind the driver or in the first row back is acceptable.

7. A driver moves to Vermont with an out-of-state CDL that carries a hazardous materials endorsement. When is the written HazMat test NOT required for the transfer?
Correct answer: When there is written proof the test was passed in the two years before the transfer
A written test is required for the endorsement unless the driver supplies written proof that the test was taken and passed during the two years before the transfer. The DMV must also be able to verify the current TSA background check and fingerprinting.

8. Vermont issues a temporary license when you apply for an Enhanced Driver's License (EDL). What does the manual say about that temporary license?
Correct answer: It cannot be used for border crossing
The EDL itself takes at least two weeks to arrive. The temporary license issued in the meantime cannot be used to cross the border, so the manual advises planning ahead.

9. What does Vermont's manual say about a customer who arrives for a CDL test without having scheduled an appointment?
Correct answer: They cannot be tested
Tests are scheduled through the DMV's online system, and the manual notes that a customer with no advance appointment cannot be tested.

10. A Vermont Commercial Learner's Permit runs out before its holder has passed the skills test. What does getting another permit involve?
Correct answer: Retaking the knowledge tests, because the permit cannot be renewed

11. Most CDL drivers working in Vermont are Non-Excepted Intrastate and need a medical certificate. Which of these is NOT one of the three groups the manual lists as included?
Correct answer: Drivers of any vehicle equipped with air brakes
The list covers drivers whose vehicles are over 26,000 pounds (rating or actual weight), drivers carrying placarded hazardous materials, and drivers of vehicles designed for 16 or more passengers, counting the driver. Air brakes are not part of it.

12. A Vermont applicant wants to be licensed for vehicles with air brakes. Besides passing the air brake knowledge test, what must the applicant do for the skills test?
Correct answer: Bring an air-brake-equipped commercial vehicle to the skills test
The air brake knowledge test is one half of it. The other half is bringing an air-braked commercial vehicle (one with air over hydraulic brakes also qualifies) to the skills test. Testing in a vehicle without air brakes puts an L restriction on the license.
