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.

As a daily commuter, I'm highly sensitive to road signs. Those white numerical signs without exception indicate the maximum speed limit, specifying the highest permitted speed for that road section. Minimum speed limits are extremely rare, only appearing in specific areas like highway entrances with blue signs or additional text reminders. Adhering to this rule is crucial - speeding not only invites tickets but also increases collision risks. I recommend novices develop the habit of scanning signs; whether it's 30 or 50 in urban areas, never exceed the limit, and use cruise control assistance when necessary. Driving requires prioritizing safety, and understanding basic rules can save considerable trouble.

During driving lessons, the instructor repeatedly emphasized that all circular white signs with black numbers on the roadside indicate maximum speed limits. For example, a 50 km/h sign means the speed must not exceed 50 km/h, and exceeding it is a violation. This standard is universally applied worldwide, aiming to control speed and prevent accidents. Minimum speed limits are indicated by separate signs. I always drive slightly below the speed limit, especially being more cautious on curves or at night. Knowing these basics can make the journey safer.

When I first got my driver's license, I was confused about speed limits. Now I understand that white numbers indicate only the maximum speed limit, not the minimum. On city streets with a 40 mph limit, you should never exceed 50 mph. Minimum speed limits are usually marked with blue signs or have additional indicators. Adhering to the maximum speed limit helps reduce the risk of rear-end collisions, and I always make sure to maintain a safe distance from the car in front on highways. Simple rules, once understood, are easy to follow.

When driving on mountain roads and encountering heavy fog, I immediately slow down upon seeing the white speed limit sign indicating 30. The maximum speed limit is to prevent loss of control, while the minimum speed limit is only marked in special sections. I make it a habit to reduce speed in advance, especially during rain or snow, maintaining the speed within the posted limits has ensured my safety on multiple long-distance trips. These signs are fundamental safeguards, and understanding their meanings helps avoid mistakes.
