# Trip

A **trip** is a navigation session in one of two modes: Free Drive or Active Guidance.

-   A **Free Drive trip** is a navigation session that does not have turn-by-turn instructions to a specific destination, but still map-matches the user to a specific location and shows relevant information along their path.
-   An **Active Guidance trip** is a navigation session that has turn-by-turn instructions to a specific destination.

Usage of the Navigation SDKs for Android and iOS v2.0.0+ can be billed by trip.
