Step-by-step explanation:
The duration for which a Junior permit must be held before scheduling a road test varies by state. However, generally speaking, there is often a mandatory waiting period to ensure that the learner has sufficient time to practice driving skills. For example, some states require that the Junior permit be held for a minimum of six months, excluding any time period in which the permit is suspended or revoked. It is essential for the permit holder to be aware of the regulations in their specific state to understand the exact duration required and eligibility to take the road test.
