Arkansas Commercial Driver License (CDL) Practice Test

What is meant by Gross Combination Mass (GCM)?

Powered unit plus trailer plus cargo Trailer only Engine weight Single vehicle plus load

Correct Answer:

Powered unit plus trailer plus cargo

Explanation:

The Gross Combination Mass (GCM) refers to the maximum permissible weight of a powered unit, trailer, and cargo combined. This weight is important as it ensures that the vehicle is capable of safely operating with the added weight of a trailer and cargo. Option B is incorrect because it only refers to the weight of the trailer, not the entire combination. Option C is incorrect because it only refers to the weight of the engine, which is not necessarily the same as the powered unit. Option D is incorrect because it only refers to a single vehicle and its load, not the combination of a powered unit, trailer, and cargo. Therefore, the correct answer is A.
