Configures for which materials you want to get a notification in case the trucks assigned here cannot get rid of them. Example case is where you run out of dumping designations and mining trucks can't get rid of dirt.
Accept cargo import only via the assigned routes (this is set by default). If this is disabled, cargo can be delivered from anywhere (meaning that import routes are ignored).
Trucks assigned to a fuel station will automatically refuel excavators and tree harvesters at their working site so they don't waste their time going for fuel on their own.
Assigned trucks will follow this harvester which will load them with wood. Trucks will deliver the wood to the factory and return back to the harvester.
