Persons who successfully complete a driver's education course can receive their class A license at ______________.

Successfully completing a driver's education course typically allows individuals to apply for their Class A license at 18 years old. This age is significant because it aligns with various state laws that regulate the minimum age requirements for different classes of driver's licenses. At 18, individuals are considered adults with more responsibilities, allowing them to progress to a Class A license, which permits them to drive larger and more complex vehicles.

It's important to note that the ages mentioned in the other options correspond to different levels of driving privileges or restrictions in many jurisdictions. For example, while those younger than 18 might be eligible for a learner's permit or a Class G (graduated) license, they would not meet the age requirement for a Class A license until they reach 18 years old.
