Are you generally in the same place at around the same time each Saturday and Sunday? IOW, do you have a regular route or are your trips always different?
If you are generally at about the same place at the same time, you could maybe find a nearby church. As the previous poster said, a lot of churches asociated with colleges have Mass at odd times, that could help. At regular churches, Mass times are usually about these times: Saturday evening 5:00 or 6, sometimes a 7:30 Mass; Sunday morning: early Mass around 8, another at 9:30 or 10; and sometimes also a noon Mass.
I was surprised when I checked for Mass for a trip I was on at how many were fairly near the highway.
The number of Masses depends on the number of Catholics in the area, and in areas with a lot of Latin Americans, some of the Masses are bilingual or in Spanish (these “count”, btw). The same is true in areas with a lot of people who speak other languages, such as Chinese or ASL. The church will usually have a biblingual missal or one jn each language so you csn follow along, but you might want to get one for yourself for the times when the church doesn’t have missals.
Also, there may be other truck-drivers in your position. If y’all got together, you could take a taxi or an uber car to Mass together, and then it would be less expensive. If it’s just you, you could call the church and ask if someone could give you a ride: you’d have to set this up ahead of time.
If your routes are unpredictable, you can use Masstimes to see if there is a Mass nearby and maybe take an Uber if there is one around there. Otherwise… talk to your own priest and ask what some good practices are instead. There have been many people in this situation over the 20 centuries os the Church’s existence, the obligation is lifted altogether for serious reasons, but for your spiritual life to grow, you will want to receive the Eucharist when you are able (like at a weekday Mass), and to do something special on Sunday insofar as you can, if only to read the Bible or pray more than you usually do.
You will also want to make sure you get to Confession. Many recommend once a month, but when I was able to go once a week, my spiritual life was in so much better shape
I think it’s really great you are considering Catholicism! Welcome to CAF, and I hope we’ll all be able to welcome you to the Church!
