Match each vehicle operation scenario on the left with the minimum driver license class or required endorsement on the right.

Operating a single vehicle with a Gross Vehicle Weight Rating (GVWR) of $28,000$ pounds that is towing a small trailer with a GVWR of $6,000$ poundsClass B Commercial Driver License (CDL)
Operating a combination of vehicles with a Gross Combination Weight Rating (GCWR) of $32,000$ pounds where the towed unit has a GVWR of $12,000$ poundsClass A Commercial Driver License (CDL)
Operating a single-unit vehicle designed to transport $18$ passengers that is fitted with a permanent tank holding $1,500$ gallons of liquidCommercial Driver License with both Passenger (P) and Tank Vehicle (N) Endorsements
Operating a two-wheeled motorcycle on public roadwaysClass M Driver License (or Motorcycle Endorsement)

Answer

1. Single vehicle with GVWR of 28,000 lbs towing a 6,000 lbs trailer matches Class B CDL.
2. Combination vehicle with GCWR of 32,000 lbs towing a 12,000 lbs trailer matches Class A CDL.
3. Passenger vehicle (18 seats) carrying a 1,500-gallon liquid tank matches CDL with Passenger (P) and Tank (N) Endorsements.
4. Two-wheeled motorcycle matches Class M License (or Motorcycle Endorsement).

Each scenario correctly pairs with its legal minimum license class or endorsement based on standard regulations:
- Combination vehicles with a total GCWR of

26,001

+ lbs towing a unit over

10,000

lbs require a Class A CDL.
- Single vehicles with a GVWR of

26,001

+ lbs towing

10,000

lbs or less require a Class B CDL.
- Passenger capacity of 16+ requires a Passenger (P) endorsement, and tanks exceeding 1,000 gallons require a Tank (N) endorsement.
- Motorcycles on public roads require Class M authorization.

Step-by-Step Solution

Analyze the vehicle weight ratings for combination versus single unit vehicles

Towing a trailer over

10,000

lbs GVWR in a combination weighing over

26,000

lbs GCWR requires Class A. Towing a trailer under

10,000

lbs GVWR with a single unit over

26,000

lbs GVWR requires Class B.

Federal and state regulations set

26,001

lbs GCWR/GVWR and

10,000

lbs towed weight as the primary boundaries distinguishing Class A from Class B CDLs.

Evaluate passenger capacity and liquid tank capacity requirements

18 passengers exceeds the 16-passenger threshold for a Passenger (P) endorsement. A 1,500-gallon liquid tank exceeds the 1,000-gallon aggregate threshold for a Tank Vehicle (N) endorsement.

Endorsements must be added to a CDL when specialized vehicle characteristics (such as passenger transportation or bulk liquid haulage) are present.

Determine licensing for two-wheeled vehicles

Two-wheeled motorcycles require a Class M license or specific motorcycle endorsement.

Class M is designated specifically for two-wheeled or three-wheeled motor-driven vehicles.
