What does it mean that the display screen of Sanqiaotou in Ankang City exceeds the standard?

What do you mean by exceeding the standard on the way? Personally, I think it should be that the vehicle exceeds the speed specified in the sign or the weight of the goods. For example, the road sign says that the speed limit is 60 mph, and your speed reaches 80 mph, then you exceed the speed of 20 mph, which is called speeding. If the cutting weight of 10 ton is subtracted from 15 ton, it will exceed the standard by 5 tons. Therefore, exceeding the standard during driving is speeding or overweight.
