Merge
warning sign · diamond · yellow
Two lanes of traffic will join ahead. Adjust speed and position to allow merging.
- Visual breakdown
- Yellow diamond with a vertical arrow joined by a curved arrow entering from the side.
- Shape recognition
- Diamond = warning; the joining arrows show the exact geometry of the merge.
- Color recognition
- Yellow = caution. You may need to change speed or lane position.
- Memory trick
- Two arrows becoming one = zipper. Merging works like a zipper: alternate teeth, smooth close.
- Real-world example
- On the highway, seeing this sign means traffic is entering from an on-ramp — move left a lane if safe, or adjust speed to open a gap.
- Common mistakes
- Thinking merging traffic must always stop for you. Courteous speed adjustment prevents most merge collisions.
- Quick recall method
- Joining arrows = zipper in; make space.
