The TomTom Trucker 600 is a dashboard-mounted GPS system optimized for the needs of the trucking industry. Most notably, unlike a standard GPS, it includes and tracks critical information regarding road height, overpass height, and commercial carrying restrictions. This enables truckers to not only plan their route, but to do so without being unintentionally directed through areas where their vehicle is not allowed, does not fit, or which otherwise presents a suboptimal route for a large commercial vehicle.
