What types of vehicles can be driven with a Class 4 Commercial Driver's Licence?

A Class 4 Commercial Driver's Licence allows the holder to operate specific types of vehicles designed for passenger transport. This includes taxis, shuttles, and buses that can carry up to 24 passengers. This license is tailored to ensure that drivers are trained to safely transport people, which involves different skills and responsibilities compared to operating larger commercial trucks or specialized vehicles.

The other options do not align with the scope of the Class 4 license. For example, while option A suggests that only cars can be driven, this limits the scope of the license which encompasses larger passenger vehicles. Option B includes all commercial trucks, which fall under different licensing categories that require a Class 3 or higher. Option D incorrectly suggests that motorcycles and heavy trucks, which also require specialized licenses, can be managed under a Class 4. Therefore, the emphasis on the capability to operate passenger vehicles within the specified limit of the Class 4 license makes the correct answer relevant and precise.
