Narrow Bridge
warning sign · diamond · yellow
The bridge ahead is narrower than the road — reduced clearance on both sides, possibly without shoulders.
- Visual breakdown
- Yellow diamond showing the road's edge lines pinching inward where the bridge begins.
- Shape recognition
- The pinched edge lines are the message: your margins shrink at the structure.
- Color recognition
- Yellow physical-hazard warning, cousin of low-clearance — the structure won't flex.
- Memory trick
- Lines squeeze in = mirrors squeeze in. Center yourself, meet no one on the span if you can.
- Real-world example
- On a one-and-a-half-lane country bridge, the courteous move is to let an oncoming truck clear the span before you enter.
- Common mistakes
- Hugging the edge line onto a bridge with no shoulder — the rail is closer than it looks; hold your lane center.
- Quick recall method
- Pinched lines = tight bridge; center up, slow down.
