A danger sign is generally what shape?

A danger sign is typically triangular in shape. This design is widely recognized and used to alert drivers to potential hazards or unsafe conditions on the road. The triangular shape allows these signs to stand out effectively from other types of signs, drawing attention and conveying the need for caution. In many instances, the point of the triangle is oriented upwards, which helps make the sign easily identifiable from a distance.

The other shapes mentioned have different purposes: square signs usually convey regulatory information or guidance, circular signs are typically used for transportation-related signals like speed limits, and hexagonal shapes are commonly found in stop signs. Each shape is designed for specific categories of signs, which helps drivers quickly understand and react to the information being presented.
