Step-by-step explanation:
In New Jersey, a person holding a valid driver permit is required to be accompanied by an adult supervising driver. This supervising driver must be seated in the front passenger seat, be at least 21 years old, and possess a valid New Jersey driver's license. Furthermore, the supervising driver should have a minimum of three years of driving experience. These regulations are put in place to ensure the safety of the new driver and others on the road by providing guidance and supervision during the permit phase of learning to drive.
