Hey Tyler! In my experience, truck drivers are generally on the road for 3 days straight (72 hours) per week, with the remaining 4 days being off days. This varies by company, so I'd recommend Googling some of the top trucking companies and searching their websites or contacting their hiring department for more information.
A lot depends on how many hours you want to drive yourself. You can max out or set your own/ follow your employer's schedule. Either way, there are laws governing how many hours a week you can drive here: https://www.fmcsa.dot.gov/regulations/hours-service/summary-hours-service-regulations.
