Three Year Junior Fishing License [Does it expire when I become an adult?]

If I were to purchase a three year junior fishing license at the age of seventeen, would I have to buy an adult license when I turn eighteen even though the three years are not up?
Answer: 
Not for fishing. If you purchase a 3 year fishing license at the age of 17, the license allows you to fish until the license expires on December 31 of the third year. Please contact our license section at 208-334-2592 if you have additional questions.
