Which class of license is required to drive any tractor-trailer combination?

B
C
G
A class A license

The correct answer is: A class A license

A class B license is incorrect because it is specifically for heavy straight vehicles, not tractor-trailers which have both a tractor and a trailer. Class C is incorrect because it is a basic license, usually for small passenger vehicles. Class G is incorrect because it is a specific type of motorcycle license. The correct answer is a class A license because it is specifically for operating any combination of vehicles with a total weight of more than 26,000 pounds, including tractor-trailer combinations.
