Why Should Vehicles on the Auxiliary Road Yield to Those on the Main Road?

[Elizabeth]

Main roads typically have higher traffic volume and faster-moving vehicles. The specific reasons are as follows: 1. Mainline: The main road serves as the primary route, while the auxiliary road functions as a secondary route, requiring vehicles on the auxiliary road to yield to those on the main road. 2. Road Surface: Main roads are wider and accommodate more traffic, whereas auxiliary roads are narrower and generally have slower speeds, necessitating yielding. Additional Information: Auxiliary roads in ground-level expressways should be located on one or both sides of the main road. For elevated roads, auxiliary roads should be situated at ground level beneath the elevated structure. In urban areas, auxiliary roads should preferably be continuous. In suburban expressways, auxiliary roads may be continuous or intermittent. Auxiliary roads on both sides of the main road should adopt one-way traffic, while those on a single side may allow two-way traffic.
