I would think he said 14 because he felt at that age they could be off fishing on their own and at that age they should be adult enough to take a test, I would think seniors would need to take the test too..just because they don't need a licence to fish, doesn't mean they don't need to know the rules to fish...they must obey the rules just like a licenced person, so why not make them take a test....
not that I agree with testing in general
