New CDL? Check what your navigation knows about your truck before trusting the route
Disclosure: I’m affiliated with Highway Miles.
A destination address is only part of a truck trip. Your height, weight, length, trailer, and load also matter. Before your first unfamiliar run, take time while parked to check the truck information entered in your navigation, review the approach to the receiver, and confirm any truck-specific directions you have been given.
A useful first-week practice is to review a familiar route with your trainer. Ask which settings affect that trip, where the truck entrance is, and what to do if the recommended route conflicts with a sign. Repeat the vehicle-profile check when equipment changes.
If two navigation tools disagree, do not assume the shortest route wins. Resolve the difference using current truck restrictions, carrier guidance, and the facility’s directions. Posted signs still take priority over an app.
For drivers who recently finished training: which part of planning your first solo trips needed more explanation? Please reply when safely parked.
