Road signs/Two-Way Traffic Sign
Two-Way Traffic Sign: what it means and what to do
A two-way traffic sign means a one-way street or roadway ends ahead and you will then share the road with oncoming traffic. Keep to the right of the centre line.
What it looks like
A yellow diamond with two black arrows, one pointing up and one pointing down.
What to do
- Stay in your lane to the right of the centre line.
- Expect oncoming vehicles; the road no longer separates the two directions.
- Do not pass until you can see far enough ahead, and remember the sign may repeat along the road.
On the permit test
Tests show the two arrows and ask what has changed; the answer is two-way traffic ahead.
