What are the two types of speed signs?

The two types of speed signs are speed limit signs and advisory speed signs. Speed limit signs are regulatory signs that indicate the maximum speed at which vehicles can legally travel on a particular stretch of road. These signs are enforced by law, meaning that drivers can be penalized for exceeding the speed limit.

Advisory speed signs, on the other hand, provide guidance to drivers about recommended speeds for safe operation under certain conditions. These signs are typically used in conjunction with curves, intersections, or other road features where a lower speed is advisable for safety, but not mandatory. They are meant to enhance safety by suggesting an appropriate speed rather than enforcing a strict limit.

Choosing this answer reflects an understanding of how different types of speed signs function in regulating and guiding driver behavior on the road.
