GPS

Truck GPS devices do not limit you to only truck routes. Truck routes do not mean that you can't use other routes, at least in the US. Truck routes are informational and indicate that a truck would find the route more suitable. Trucks are only restricted by specific truck restricted road designations (as well as weight and height restrictions). A GPS may favor truck routes but, if it has a robust traffic source or historical traffic data, it's likely because it's actually the quicker way to go.

Perhaps it varies by which model of GPS you have, but with the Garmin Trucker's version that we had, we were never routed via a road/street that was not marked as a truck route. The tipping point for us to replace it was when we were routed a couple of miles out of our way when headed for a campground in New York. Found out from the campground staff the next morning that there was a much shorter path back to the interstate, but used roads that the local municipality had not designated as truck routes. This was three or four years ago, though, so perhaps things have changed since then.
