Are the white numbers indicating the maximum speed limit or the minimum speed limit?

Numbers within the red circle represent the maximum speed limit (white numbers on a red circle with black background), while numbers within the blue circle indicate the minimum speed limit (white numbers on a blue background). Below is a detailed introduction about vehicle speed: Overview: Vehicle speed refers to the distance a vehicle travels per unit of time, commonly referred to as speed, with the usual units being kilometers per hour or meters per second. Vehicle speed is one of the three parameters used to describe traffic flow and holds significant importance in the study of traffic flow theory. Others: Vehicle speed can also broadly refer to the speed of motor vehicles. To suit different purposes, vehicle speed is mainly categorized into spot speed, segment speed, and design speed. Spot speed is the instantaneous speed of a vehicle passing a specified point on the road. Design speed is the speed set to determine the design indicators of various geometric elements of the road and to ensure their mutual coordination.
I've been driving for several years now, and I remember when I first started learning at driving school, I always had trouble distinguishing the color meanings of speed limit signs. Later, my instructor pointed to those roadside signs with white numbers and said, these are definitely maximum speed limits—for example, 60 means you must not exceed 60 kilometers per hour. The large numbers on highways also indicate maximum speed limits, reminding everyone not to speed to avoid accidents or fines. Actually, minimum speed limits are rarely used and are usually displayed with blue signs in tunnels or on bridges. It's a good habit to develop while driving: when you see white numbers, automatically slow down—it's safer, saves money, and prevents penalty points. Be extra cautious in rainy or foggy conditions; the maximum speed limit isn't the target speed, and adjusting flexibly makes for a steadier drive.
