Compulsory Direction Sign
Compulsory-direction signs force a movement (e.g. turn left only). As blue command signs they state what you must do, unlike a red-bordered prohibition.
Meaning
Blue circle with a white arrow (turn left, right or proceed ahead).
Required driver response
Travel only in the direction the arrow indicates.
Question patterns
- “What does this sign mean?” — recognition of meaning.
- “What must you do when you see this sign?” — required response.
- Distractor trap: confusing the blue command arrow with a blue one-way information arrow.
