Google Maps doesn't have a built-in truck route function, but third-party software applications can work in conjunction with Google Maps to create a truck route. For example, download the Sygic Truck & RV GPS Navigation app from the Google Play Store to your Android device, then install the Sygic Truck Route Sender extension on the Chrome or Firefox browser on your desktop. Add a driver, create a map on the Google Maps web page, then use the browser extension to send the route to a driver or mobile device.
