Do Not Enter
regulatory sign · rectangle v · white
The road ahead is closed to traffic in your direction. Do not drive past this sign.
- Visual breakdown
- Square white sign with a red circle and a horizontal white bar across the middle — like a blocked doorway.
- Shape recognition
- Square sign dominated by a red circle; the white horizontal bar is the visual 'barrier.'
- Color recognition
- Red circle = prohibition. The white bar across the center reads like a closed gate.
- Memory trick
- The white bar is a closed gate across a red porthole — the road is shut to you.
- Real-world example
- Posted at freeway off-ramps so drivers don't accidentally enter the highway against traffic.
- Common mistakes
- Confusing it with Wrong Way. Do Not Enter appears first, at the mouth of the road; Wrong Way confirms you've already made the error.
- Quick recall method
- Red circle + white bar = closed gate, stay out.
