Final answer:
A learners permit must be validated at a Department of Motor Vehicles (DMV) or equivalent state agency after completing a driver training course before it can be used for practice driving.
Step-by-step explanation:
Upon completion of the approved driver training course and before practice driving, the permit holder must have the permit validated at any Department of Motor Vehicles (DMV) or equivalent state agency responsible for driver licensing. It is essential for permit holders to ensure that their permits are legally authorized for use on public roads, and the validation process is a critical step in this. Often, this entails presenting the requisite documentation to prove completion of a driver's education course, passing a vision test, and potentially other requirements set by the state’s laws.
