What's the reasonable average speed for trucks in North America?

Interest data. Speed limits are higher over here but our real-world averages probably arent as different as you'd think. Most company trucks are governed around 65 mph, and on an absolutley perfect day a long-haul driver might average 55 mph

That drops off a cliff for regional and local work though. With all the city traffic and time spent waiting at docks, your numbers in the 25-35 mph range look familiar ... It's less about the speedometer and more about what the clock lets you do.
