# AddExcludedVehicleToSystem

### Description

Excluded vehicles are a special kind of vehicle marked as **Don't Instantiate** inside the Vehicle Pool. These vehicles will not be instantiated by the system unless the user specifies to be instantiated using this method. Read more about them [Vehicle Pool](/mobile-traffic-system/setup-guide/vehicle-pool.md#add-vehicles-to-the-pool)

The AddExcludedVehicleToSystem adds a previously excluded vehicle back to the Traffic System and the vehicle behaves normally.
