What it means
A blue disc with a white arrow is an order, not advice. The arrow may point left or right, depending on the road layout ahead.
What to do
You must go the way the arrow points. No other direction is allowed here.
How to read mandatory signs
Mandatory signs are blue circles, and they tell you what you must do. If you see a blue disc, it's an order rather than a suggestion.
