I can't say I know the law in every state so I typically don't say absolutes like that. If that's true, thanks for clarifying/correcting.

Also, it looks like you're right for at least the states I normally deal with. Looking back the first job I had started when I was still 15, I must have just blended those shift schedule restrictions during the rest of my time working as 16-17 as well. So yeah, I guess that's probably true.
