Follow the Greens in MSFS

Review your MSFS settings before using these controls.

Follow the Greens

Green taxiway centerline lights a controller switches on to lead you along your cleared route (figure below).

Controller-driven and VATSIM-only - there is nothing to switch on in the app.
Needs a controller who offers it and a published taxi network for the scenery you fly. Check the main website for supported airports.
A controller starts FTG. A consent popup (first figure below) names them, with Accept / Reject. (Turn on Auto-accept in Settings - the popup offers the same checkbox.)
Accept, and an always-on-top mini card (second figure below) shows the session is live. Hide it with Do not show FTG card and cancel from the status-card banner instead.
Greens trace your route on your installed scenery. Follow them. The lit stretch rolls forward with you as ATC advances the route.
The greens stop at your hold-short bar - where the line ends is where you hold. They extend past it once you are cleared, and never light green past a red bar.
