# Turn-by-turn navigation

Turn-by-turn navigation, also referred to as active guidance, is likely what comes to mind when you think about a typical navigation experience: a user receives turn-by-turn instructions as they progress along the route. If a trip session is running and a route is selected, the Navigation SDK goes into an internal `active guidance` state.
