Narrow Bridge Sign
The narrow-bridge warning shows two parapet bars pinching the road, marking a bridge where the carriageway narrows. It is distinct from the general Road Narrows Sign because the constriction is the bridge structure itself, which often cannot take two vehicles abreast.
Meaning
A narrow bridge is ahead where the road width is reduced.
Required driver response
Slow down and, if the bridge is too narrow for two vehicles, do not cross at the same time as an oncoming vehicle — yield as needed.
Question patterns
- “What does this sign mean?” — recognition of meaning.
