What does the yellow speed sign mean?

[StPresley]

The yellow speed sign indicates the maximum speed limit. Speed limits typically refer to the upper limit and are generally implemented to prevent drivers from creating safety hazards due to speeding. On highways, there are also minimum speed limits. Since the speed of ordinary vehicles on highways and expressways is very high, if certain vehicles travel too slowly, they can become obstacles on the road, easily leading to rear-end collisions. Below is additional information about highway signs: 1. Destination information: The distances to key cities and regions along the route are periodically reminded and marked at intervals. These prompts allow drivers to gauge the distance to their destination and make advance plans for arrival time, rest stops, refueling, etc. 2. Lane and speed limit information: Above the driving lanes, lane information is displayed at intervals, including speed limit reminders, lane names, or vehicle restrictions. It's important to note that speed limits vary for each lane. For example, driving at 120 km/h in a lane with a 100 km/h limit may result in a traffic violation being recorded by surveillance cameras.
