Practical to get into the industry at all at 18?

***TL;DR,*** **Is it at all practical (probably not, but I want to work it out) to potentially buy and drive at 18, considering all the insurance and other unforeseen things?** I understand the burden of owning a semi and the high maintenance costs and fuel, this is more of a genuine passion for me due to the influence transportation has had on my life, I 100% will eventually try it out at some point in my life, *I'm just wondering if it's even worth it to attempt getting into it this early or just waiting until later 20's*. If owning a semi is def a bad choice then any alternatives? I've thought about driving dumps or cement since I've heard people can be hired younger for that Funding to go to CDL school isn't a concern for me since I have money saved, it's just the question on practicality at all so I figured it'd be best to ask actual drivers. I understand many companies won't hire this young, but my father has a transportation business and I can for sure try through that. *I'm not looking for comments on all the cons* like how bad the industry is, far from home (Don't care about home time, not married and can't leave state anyway) or stuff like that. I know what I'd be getting into and how hostile everything is. Grandad has drove and been an owner-op himself for years so I have a little bit of insight. Again, this is more about a genuine passion instead of worrying about making 6 figures. Thanks
