You are travelling on a main road. Which road sign ends your right of way?

You selected both the first and second signs, which is correct. The first traffic sign (an upside-down triangle with a red border) means "Yield" – when you see this, you must give way, and your right of way ends. The second sign (a yellow diamond crossed with black lines) indicates the end of a priority road. This also means your right of way on the main road ends. The third sign is just a warning about an upcoming intersection with priority to the right but does not end your current right of way. Remember: look for the "Yield" sign and the crossed-out yellow diamond as key indicators that your right of way is finished.
