Turn Left Ahead Sign
The turn-left-ahead command compels a left turn. As a blue ‘must’ sign it is the opposite of the No Left Turn Sign. The blue-vs-red distinction is a core test theme — see Road Sign Colour Code.
Meaning
You must turn left ahead.
Required driver response
Turn left only; no other direction is permitted.
Question patterns
- “What does this sign mean?” — recognition of meaning.
- “What must you do when you see it?” — required response.
- Distractor trap: confusing the blue command with the red-ringed ‘no left turn’ prohibition (the opposite).
