Which of the following is NOT a class of driver's licenses available in Manitoba?

In Manitoba, the various classes of driver's licenses are categorized based on the type of vehicles a driver is permitted to operate. Class 1 licenses allow the operation of a semi-trailer vehicle, which is essential for commercial trucking. Class 4 licenses are designated for drivers operating vehicles such as buses or taxis, which have specific passenger limits. Class 6 licenses are for motorcycles and enable individuals to legally ride motorbikes and scooters.

Class 7, on the other hand, is specifically a part of the graduated licensing system for novices, primarily aimed at providing new drivers with an opportunity to gain experience while adhering to certain restrictions. However, Class 7 is not classified as a standalone class of driver's license like the others mentioned. In the context of the question, it is not recognized as a full operating license for regular vehicles, making it the correct answer for what is NOT a class of license available for general vehicular operation in Manitoba.
