Final answer:
A Class C license is typically required for operating personal automobiles and small trucks, whereas Class A and B are for larger or specialized vehicles.
Step-by-step explanation:
Most drivers only need a Class C license to operate a personal automobile and small trucks. While the classifications can vary by state, a Class C license is typically the standard driver's license that allows individuals to operate most passenger vehicles and small trucks. The other classes of driver's licenses, which are Class A and Class B, are generally required for heavier and larger vehicles, such as semi-trucks, buses, or vehicles that carry hazardous materials or more than 15 passengers.
