CDL Fundamentals, Licensing, and Federal Regulations flashcards for Commercial Driver's License (CDL)

18 of 50 cards from the CDL Fundamentals, Licensing, and Federal Regulations deck — real questions with worked answers.

1. What are the three CDL license classes and the GVWR/GCWR thresholds that define each?

   Class A: combination with GCWR of 26,001+ lbs, where the towed unit is over 10,000 lbs GVWR. Class B: a single vehicle with GVWR of 26,001+ lbs, or such a vehicle towing a unit not over 10,000 lbs. Class C: a vehicle under the Class A/B thresholds that either carries 16+ passengers (including driver) or transports placardable hazardous materials.

2. What is the difference between GVWR and GCWR?

   GVWR (Gross Vehicle Weight Rating) is the maximum loaded weight of a single vehicle as specified by the manufacturer. GCWR (Gross Combination Weight Rating) is the maximum loaded weight of a power unit plus its towed unit(s) combined.

3. A driver with only a Class B CDL may legally operate which vehicles?

   Any single vehicle rated 26,001+ lbs GVWR (and that vehicle towing a trailer of 10,000 lbs GVWR or less), plus any Class C vehicle. A Class B holder may NOT drive a Class A combination (towing a unit over 10,000 lbs).

4. Name the six federal CDL endorsements and the privilege each grants.

   H – Hazardous materials; N – Tank vehicles; T – Double/triple trailers; P – Passenger vehicles; S – School bus; X – Combination of tank (N) and hazmat (H).

5. What additional federal requirement applies to obtaining the H (HazMat) endorsement that does not apply to other endorsements?

   The applicant must pass a TSA security threat assessment, which includes fingerprinting and a background check, in addition to passing the hazardous materials knowledge test.

6. What does CDL restriction code E mean?

   E = No manual transmission. The driver took the skills test in a vehicle with an automatic transmission and is restricted from operating a CDL vehicle equipped with a manual transmission.

7. What does CDL restriction code L mean?

   L = No air brakes. The driver either did not pass the air brake knowledge portion or took the skills test in a vehicle not equipped with full air brakes; they may not operate a CMV equipped with air brakes.

8. What does CDL restriction code Z mean?

   Z = No full air brake equipped CMV. The driver tested in a vehicle with air-over-hydraulic brakes, so they are prohibited from operating a vehicle equipped with full air brakes.

9. What do CDL restriction codes O, M, and N mean?

   O = No tractor-trailer (Class A) — tested in a Class A combination connected by a non-fifth-wheel device. M = No Class A passenger vehicle (passenger/school bus tested in Class B or C). N = No Class A and B passenger vehicle (passenger/school bus tested in a Class C vehicle).

10. What does CDL restriction code V indicate?

    V = Medical variance. It indicates there is information about a medical variance (such as a federal exemption or skill performance evaluation) on the driver's record.

11. A vehicle has a GVWR of 24,000 lbs and tows a trailer rated 12,000 lbs. What CDL class is required and why?

    Class A. The combination GCWR is 36,000 lbs (over 26,001) AND the towed unit exceeds 10,000 lbs GVWR, which defines a Class A combination.

12. A straight truck has a GVWR of 30,000 lbs and tows a 6,000 lb trailer. What CDL class is required?

    Class B. The power unit alone is 26,001+ lbs and the towed unit is 10,000 lbs or less, so the combination falls under Class B (not Class A).

13. What is the minimum age to obtain a CDL for intrastate driving, and for interstate driving or transporting hazardous materials?

    18 years old for intrastate (within one state) operation; 21 years old for interstate operation and for transporting placardable hazardous materials in any operation.

14. Why can an 18-year-old not legally drive a CMV across state lines?

    Federal regulations (FMCSA) set the minimum age for interstate CMV operation at 21. An 18- to 20-year-old may only operate a CMV intrastate, subject to state law.

15. What is a Commercial Learner's Permit (CLP) and what does it authorize?

    A CLP authorizes a permit holder to practice driving a CMV on public roads while accompanied by a person who holds a valid CDL for that class/endorsement and is seated in the front seat next to the CLP holder.

16. What test(s) must be passed to obtain a CLP?

    The applicant must pass the required knowledge (written) test(s) for the class of CDL and any endorsements sought; no skills test is required to get the CLP itself.

17. What is the mandatory 14-day holding period associated with the CLP?

    A CLP holder must wait at least 14 days after the CLP is issued before being permitted to take the CDL skills (road) test.

18. How long is a CLP valid and can it be renewed?

    A CLP is valid for 180 days. States may allow one renewal for an additional 180 days without retaking the general knowledge test.
