Can A blind curve can hide an obstacle in the road so that the driver may not have time to stop for it by the time he can see it?

Yes, a blind curve can indeed hide an obstacle on the road, posing a significant risk to drivers. When approaching such a curve, visibility is limited, making it difficult for drivers to see any hazards until they are very close. This lack of sight can reduce reaction time, potentially preventing the driver from stopping in time to avoid a collision. It is crucial for drivers to exercise caution and reduce speed when navigating blind curves to ensure safety.
