Final answer:
A speeding conviction will result in a 90-day suspension for a Massachusetts driver with a Junior Operator License.
Step-by-step explanation:
The question concerns traffic regulations for junior operators in Massachusetts (MA), specifically relating to the consequences of a speeding conviction for someone holding a Junior Operator License. The answer to the question, "One conviction of speeding will result in suspension for a period of ___ days for a MA driver who holds a Junior Operator License," is 90 days. If a junior operator is convicted of speeding, their license will be suspended for this period of time.
