What do speed limit signs indicate?

Speed limit signs indicate the maximum or minimum speed that vehicles are legally allowed to travel on a particular stretch of road. These signs serve as a crucial part of traffic regulation, promoting safety and ensuring a smooth flow of traffic. The maximum speed limit is the highest speed at which you may legally operate your vehicle under ideal conditions, while the minimum speed limit is intended to prevent slow-moving vehicles from disrupting traffic flow. Understanding speed limits is essential for all drivers, as adhering to these signs helps reduce the likelihood of accidents and enhances overall road safety.

While construction zone speed, normal driving speed, and school zone speed do play significant roles in specific driving scenarios, they are not the primary purpose of general speed limit signs, which universally indicate the basic maximum or minimum speeds for all drivers.
