This indicates a highway sign for 'minimum speed limit of 50 km/h'. Below is relevant information about minimum speed limits: 1. Meaning and Examples: Road traffic signs are facilities that convey specific information through graphic symbols, colors, and text to manage traffic. They play a role in ensuring smooth road traffic and driving safety, so drivers and all road users must comply. Traffic safety slogans can enhance drivers' and road users' awareness of voluntarily obeying traffic laws, which is significant for building a safe and smooth traffic environment. 2. Laws and Regulations: According to Article 78 of the 'Regulations for the Implementation of the Road Traffic Safety Law' (hereinafter referred to as the 'Regulations'), highways must indicate the driving speed of lanes, with the maximum speed not exceeding 120 km/h and the minimum speed not less than 60 km/h. For roads with two lanes in the same direction, the minimum speed of the left lane is 100 km/h.

The blue background with white number 50 is the minimum speed limit sign in road traffic signs, indicating that you must not drive below 50 kilometers per hour on this road. This type of sign is commonly seen on highways or multi-lane roads, reminding you not to drive too slowly and affect the vehicles behind. I’ve seen many of them while driving, such as on suburban expressways. If your speed drops below 40, it may be considered a safety risk, potentially resulting in a ticket for ultra-low speed or a warning from traffic police. Remember to obey it because driving too slowly can actually lead to accidents, such as rear-end collisions caused by sudden braking. It’s best to maintain a steady speed, especially in rainy or foggy weather, paying extra attention to the minimum speed limit to ensure safe driving for yourself and others.

As a long-distance driver, I'm all too familiar with the blue background and white numbers '50'—it signifies the minimum speed limit of 50 kilometers per hour, reminding you not to drive too slowly. Roads are designed this way to ensure smooth traffic flow and prevent vehicles traveling at 40 km/h from obstructing the stream, which could lead to congestion or accidents. I've seen many novice drivers on highways overlook this, only to be flashed by following vehicles. Make it a habit to glance at your speedometer, especially in sections like tunnels or bridges where such signs are posted. Maintaining a balanced speed is key—too fast is unacceptable, but driving too slow also violates regulations and could result in a ticket. By consistently practicing safe driving techniques, you can easily handle these situations.

A blue background with white numbers '50' indicates the minimum speed limit, requiring vehicles not to drive below 50 kilometers per hour. It is part of traffic regulations designed to control road speeds and prevent congestion or accidents caused by excessively slow driving. I always pay extra attention to such signs, especially on urban main roads. Complying with them ensures smooth traffic flow and avoids potential hazards from slow driving. The law clearly defines the function of these signs, and failure to comply may result in penalties or fines.
