Is a speed of 180 km/h considered fast?

[ElainaMarie]

Speed of 180 km/h is considered fast. Here is some relevant information about vehicle speed: 1. Introduction: Running speed refers to the average speed at which a vehicle travels over a certain road section. It is calculated by dividing the length of the road section by the pure driving time (total trip time minus all stopping times), and is used to analyze the difficulty of driving and traffic capacity on that road section. It can be obtained through test vehicle surveys. To ensure the accuracy of test data, it is generally required that the test vehicle travels 12-16 times on the road section, and the speed value is obtained through statistical analysis. 2. Relevant regulations: According to the implementing regulations of relevant laws, motor vehicles must not exceed the speed indicated by speed limit signs when driving on roads. On roads without a center line, the maximum speed cannot exceed 40 km/h. The maximum speed on urban roads cannot exceed 30 km/h. On roads with only one motor vehicle lane in the same direction, the speed cannot exceed 70 km/h, and on urban roads, it cannot exceed 50 km/h. Driving at excessively high speeds can easily cause traffic accidents.
