Ontario MTO Truck Knowledge Practice Test

An applicant for a class A or D driver's license must?

1. Be at least 21

2. Be at least 18

3. Hold a motorcycle license

4. Complete a medical exam

The correct answer is: Be at least 18

The requirement for an applicant for a class A or D driver's license to be at least 18 years old is rooted in the necessity for young drivers to have adequate maturity and responsibility when operating large vehicles. At 18, individuals are legally considered adults and can better understand and adhere to the driving regulations and practices that are critical when managing heavy equipment or vehicles. While there are other relevant requirements, such as passing a series of tests and, for some classes of licenses, undergoing medical exams, these do not impact the minimum age requirement directly. For instance, not all applicants need to hold a motorcycle license in order to pursue a class A or D license; this is a separate category of driving that has its own specific requirements. The age requirement helps ensure that drivers in these categories have the necessary life experience and judgment to drive safely and responsibly.
