What is the speed limit at uncontrolled intersections without traffic signals?

[AugustLee]

When passing through an uncontrolled intersection without traffic signals or speed limit signs, the maximum driving speed shall not exceed 30 kilometers per hour. Below is detailed information about vehicle speed: 1. Overview: Vehicle speed refers to the distance a vehicle travels per unit time, abbreviated as speed, commonly measured in kilometers/hour or meters/second. Vehicle speed is one of the three key parameters describing traffic flow and holds significant importance in traffic flow theory research. 2. Others: Vehicle speed can also generally refer to motor vehicle speed. To accommodate different purposes, vehicle speeds are mainly categorized into spot speed, segment speed, and design speed. Spot speed refers to the instantaneous speed when a vehicle passes a specific point on the road. Design speed is the predetermined speed used to establish design indicators for various geometric elements of the road and ensure their coordination.
