What are the requirements of a supervising driver?

A supervising driver must typically hold a valid driver's license for the type of vehicle being driven and have a clean driving record. They should be at least 21 years old, although this age requirement may vary by jurisdiction. Additionally, the supervising driver must have a certain amount of driving experience, often at least three years, and be present in the front passenger seat during the learner's driving practice. It's also important for them to provide guidance, support, and ensure safety throughout the driving session.
