What does an advisory speed sign indicate?

An advisory speed sign indicates recommended speeds around a turn or along roadway conditions that may require slower speeds for safe navigation. These signs are typically used in areas where the road curves or where there are varying conditions like construction, adverse weather, or steep grades. The purpose of these signs is to enhance safety by advising drivers to reduce their speeds as necessary for the situation, rather than imposing a legal requirement as a mandatory speed limit would. This recommendation allows drivers to make informed decisions about their speed based on the specific circumstances of the road ahead. Understanding the role of advisory speed signs can help drivers navigate potentially hazardous areas more safely.
