What is the maximum speed limit for motor vehicles when descending a steep slope?

[RafaelDella]

Motor vehicles must not exceed 30km/h when descending a steep slope. According to the "Highway Speed Limit Standards" and Article 42 of the "Road Traffic Safety Law", it is clearly stipulated that motor vehicles driving on the road must not exceed the maximum speed indicated by speed limit signs. The maximum speed limit for specific road sections should be determined according to the following standards: On highways without a center line, the speed limit is 40 kilometers per hour; On highways with only one motor vehicle lane in the same direction, the speed limit is 70 kilometers per hour; When entering or exiting non-motorized lanes, passing railway crossings, sharp curves, narrow roads, narrow bridges, or making U-turns, turns, or descending steep slopes, the speed limit is 30 kilometers per hour; The maximum speed limit on expressways is 120 kilometers per hour.
