What type of adult is NOT permitted to accompany a learner driver?

A learner driver must be accompanied by a qualified adult to ensure safety and legal compliance while operating a vehicle. The type of adult that is not allowed to accompany a learner driver is an individual who does not possess a valid driver's license. This is critical because a licensed adult is necessary not only to guide the learner in road rules and safe driving practices but also to take control of the vehicle if needed.

Without a valid license, an adult cannot effectively fulfill this role, and allowing an unlicensed person to accompany a learner could lead to unsafe situations and legal ramifications. Other options, such as legal guardians, approved driving instructors, and responsible adults with signed financial responsibility, are all recognized and authorized types of supervisors for learner drivers, providing guidance and maintaining safety during the driving process.
