A curve hazard is a section of road which presents a risk to motorists due to a single curve. Curves present a hazard of obscured visibility of oncoming traffic as well as a short turning radius. This tagging is applied to roads that are signed for dangerous curves and should not be applied indiscriminately to roads merely because they have curves.
For extended curves, the curve=* tag can be added, indicating the specific type of curve:

How to map
Tagging can be applied to the curved section of road or the location of the signage:
- Place a node
at the location of the curve hazard traffic sign, tagged traffic_sign=hazard (or code) + hazard=curve. - Tag a node along a highway=* way
at the location of the sign - Tag the section of highway=* where the curve hazard is present.
