Truck Navigation Basics: How Truck-Safe GPS Works and How to Choose

A car map app plans the fastest route for a car. A truck navigation app plans a route your truck can legally and physically take, using its height, weight, length and load. That one difference explains most of what's in this section.

If you're new to this, read the guides in order: first the difference between truck and regular GPS, then how a truck route is actually built from the truck profile and restriction data, then what consumer apps like Google Maps can and can't do. The last two cover the practical choice: a dedicated GPS unit or an app on a phone or tablet, and what changes for box trucks, which often get treated like cars when they shouldn't be.
