The handler interface for requesting to activate the car’s signals.


@protocol INActivateCarSignalIntentHandling


Use the methods of the INActivateCarSignalIntentHandling protocol to resolve, confirm, and handle requests to activate signals on the user’s car. Adopt this protocol in an object of your Intents extension that is capable of activating the car’s signals.
