A motor vehicle weighing under 4000 lbs (unladen) may not tow any vehicle weighing 6000 lbs or more gross under:

• A. Class C DL rules
• B. Class A DL rules
• C. Class B DL rules
• D. Motorcycle license rules

Answer: (A)

The key idea here is which license class governs towing based on weight. In California, a Class C license covers regular passenger vehicles and light trucks, and it allows you to tow a trailer with a gross vehicle weight rating (GVWR) up to 10,000 pounds. So when the towing vehicle weighs less than 4,000 pounds and you’re pulling a trailer with a gross weight around 6,000 pounds, you’re still within the Class C towing limit. That means the towing situation falls under Class C rules rather than requiring the heavier CDL classifications. You’d only move to Class A or B if the towed vehicle’s weight exceeded 10,000 pounds or the combined weight exceeded certain CDL thresholds (like a 26,001 pound GCWR or more). The motorcycle license rules are not applicable here.
