Average National Pay. According to the Bureau of Labor Statistics, long-haul truck drivers reported an average wage of $19.40 an hour as of 2012. The average long-haul truck driver reportedly earned an average annual salary of $40,360. However, pay fluctuates by location, by industry, and according to how much freight a long-haul trucker delivers per year, leading to a range of possible salaries.
However, if we assume an average weighted driver wage of $21.90 per hour, which factors in just a fraction of driver expenses, and assume drivers work 30 hours a week (again, not necessarily typical, but a middle range of the hours worked by the eight drivers we spoke to), we can assume a rough projected yearly driver salary of $34,164.
