Two-way traffic’ sign Sometimes you’ll see a red triangular sign with two black arrows pointing in opposite directions. These are used to make you aware that you’re about to leave a separated one-way street and enter a two-way road. If the arrows are positioned vertically, it means two-way traffic straight ahead. You should keep to the left-hand side of the road and be aware of oncoming traffic. If they’re horizontal, it indicates that you’ll have to turn either left or right to join the two-way road ahead.
