I don't know how many pocketnow readers are in the trucking industry, if you are, raise your hand. Great! ALK has released a Truck version of their CoPilot Live software for Android.
I've told you about CoPilot Live before, but for those of you who've forgotten, it's a GPS app that gives you spoken turn-by-turn directions from maps that are local to your sdcard, no data connection required. This comes in very handy when you're out in the middle of nowhere, with little to no data connection available. Take my word for it.
CoPilot Live Truck, as its name implies, is written to help truck drivers get to their destinations, taking into consideration all the limitations and restrictions big-rigs have that normal vehicles don't. According to the developer, using the software will help truck drivers "reduce fuel costs and out-of-route mileage, increase efficiency and avoid costly fines and vehicle damage" and "takes into account truck-restricted and prohibited roads to provide safe and reliable routes on truck-legal roads".
The app calculates optimal routes based on the height, length, and width of the truck and type of cargo, and routes you around restricted routes.
