Help with this riddle?

You are travelling down a road when the road suddenly branches out in three directions. There is a person at the split to whom you can ask a single yes/no question. What is the ONE yes/no question you can ask that will allow you to determine which direction to take?

......... and, one always lies, the other always tells the truth.
U ask either one, "which would Ur friend say is the right path?" and go the other.
If he's the liar - he would quote his friend wrongly, and show U the wrong way
If he's the truth-teller, again, he'd quote his friend wrongly, and show U the wrong way.

This reminds me of the infamous bottle riddle. I'm going to say that it has the same answer: you keep asking "is this the right road" several times until you get the right road. You said you can only ask one yes or no question, not only one question.
