What is the rule when exiting a private property, courtyard, or petrol station to join a public road?

1. You must yield right-of-way to all vehicles, pedestrians, and cyclists circulating on the public road
2. You have priority over vehicles coming from your left under standard priority-to-the-right
3. You have priority if you sound your horn before crossing the property line
4. Public road traffic must stop to allow vehicles to exit private properties
