Having never played a trucking game, I have to say that this is a pretty decent game.
The gist of this game is: you get some cargo contract, you drive to your destination, you get paid. Rinse, lather repeat. No, it isn't super exciting - mostly I just enjoy the long drives and occasional road challenges like heavy traffic or navigating tight roads with large loads. There's a very simple cb radio system that is fun to break the monotony. It's a chill game overall.
The map covers parts of the USA, Canada and Mexico. The world feels appropriately large, but it is "compacted" and cities are made of just a few major streets and points of interest.
There is no real "point" to the game though: it's a "sandbox" where you do what you want. There is some progression to it: you start with a single truck and a bit of money and once you get more money eventually you start buying more trucks and hiring drivers that work for you.
There are a few downsides. The game feels "cheap". Graphics aren't amazing (they are serviceable). Audio is kinda bad. It crashes a bit (always save before interacting with notebook!). The game also has no tutorial and only a short manual. It is confusing for a newcomer. It lacks a the polish that you expect in modern games.
The police system is also under-developed. You gain "wanted" level for doing illegal things, which is fine, but sometimes it isn't obvious what is going on - for example: driving after 6pm with your headlights off gives you wanted level but you might not notice this and you will rack up a huge amount and possibly a fine.
Visibility is also terrible which you will feel while you struggle to get a good angle to be able to see what you are doing while backing up with your trailer.
That said, overall, the game is a chill experience despite the flaws and I am happy with it. The price even discounted is a bit steep for what you are getting IMHO. If you are bored and want something different you can consider this game.
