Truck driving is not something I would recommend anyone shoot for who is that young, especially considering we're going to have AI driven vehicles soon.
It's not a bad fall-back, but it's tough on the body, and on a family life, from what I hear. If someone is drawn to it, that's different, and they can make decent pay.
I think everyone should get a higher education, even if it's just for fun while they learn a trade. Community colleges are often absurdly cheap, easily afforded paying out of pocket even. You don't have to go in debt necessarily to afford college. If you go to a local college and do really well, you might also get scholarships or justify taking out a loan to go to a more prestigious school, all sorts of ways you can play it.
Trades often grown into sole proprietorships, and having a little background knowledge in finance, some good math skills, exposure to other subjects that get you thinking outside your comfort zone...I think it's a good thing to do even if you're gonna do a trade.
Or just part-time college/night classes, maybe a 1 or 2-year certificate, that's cool too. Anything is better than nothing in many cases, even if your grades are poor, the environment is pretty good with teachers, counselors, and other students looking to start careers, etc, often in your own age group. I think it's something to take advantage of personally. Everyone should aim for a well-rounded education in the liberal arts on top of their chosen career or field of study.
You only get exposure to some tiny fraction of career choices and disciplines without college/university. I use to hire right out of 3 local community colleges into a trade-like technical job. Not a one of them would have ever had the opportunity had they not been there.
We've invested lots of money into those institutions, avail yourself of that investment! And if you flunk out, who cares, take classes that interest you and forget the grade. But if you go that route, do it at local colleges that are cheap
