Trailers are considered additional equipment (goods, tools, utility trailers etc.) that are attached to the main vehicle and doesn’t have its own tracker or controller. Monitoring trailers is similar to tracking drivers in many ways. Add-on asset beacons are required to tracking trailers. Trailer tracking is only available in Fleet Advanced and Premium Packages.
To work with trailers, click on the Trailers tab in the top panel or select Trailers in the main menu customizer.
