No Entry Sign
No Entry is a prohibition sign placed at the wrong-way end of one-way streets and restricted roads. Going past it means driving against legal traffic flow.
Meaning
Solid red circle with a single white horizontal bar.
Required driver response
Do not enter beyond this sign; find an alternative route.
Question patterns
- “What does this sign mean?” — recognition of meaning.
- “What must you do when you see this sign?” — required response.
- Distractor trap: confusing it with a one-way sign (no-entry forbids entry; one-way shows the permitted direction of flow).
