Final answer:
The suspension period for a Junior Operator's learner's permit after driving without required adult supervision will vary according to state law, so the specific number of days for a first offense must be checked with the local DMV.
Step-by-step explanation:
A Junior Operator who holds a learner's permit must indeed be accompanied by a licensed driver at least 21 years of age at all times when driving. If he or she is convicted of driving without adult supervision, the suspension period for the permit will vary by state law. Since the information provided does not include the specific days for the suspension, and to remain factually accurate, I am unable to provide the exact period of suspension for the first offense. It's important to check with your local department of motor vehicles (DMV) for the most current and accurate information regarding penalties for traffic violations for junior operators.
