Why Does the Main Road Vehicle Have the Right of Way Over the Side Road Vehicle?
3 Answers
The main road is designated as such due to its high traffic volume, serving as the arterial route, while the side road functions as the feeder route. Feeder road vehicles must yield to arterial road vehicles. Typically, main roads have more lanes and higher speed limits, hence side road vehicles are required to give way to main road traffic. When traffic pressure on the main road becomes excessive, some vehicles may temporarily use the side roads to alleviate congestion. Interchanges. Relevant information about traffic signals is as follows: 1. Introduction: Traffic signals are devices that regulate traffic flow, generally consisting of red, green, and yellow lights. A red light indicates prohibition of passage, a green light permits passage, and a yellow light serves as a warning. 2. Control Methods: The most basic control method is fixed-time control at individual intersections. Line control and area control can also employ fixed-time methods, referred to as static line control systems and static area control systems respectively.
I have over a decade of driving experience and often encounter road paving vehicles during construction. The main reason for giving priority to main road traffic is efficiency. Main roads have high traffic volume and faster speeds. If paving vehicles were allowed to proceed slowly first, the entire road would become completely congested. I remember last week on the highway when a paving vehicle pulled over to yield, allowing hundreds of main road vehicles to pass smoothly within minutes. Moreover, traffic regulations clearly state that special operation vehicles must yield to normally moving traffic during construction. Paving vehicles themselves move slowly and occupy significant space during operation, so letting them go first would actually create more traffic chaos. Some road sections even require advance warning signs to direct main road traffic to pass through construction zones first. Simply put, this is about regulating traffic flow based on demand—whoever has greater volume and faster speed gets priority, which is the most reasonable approach.
From the perspective of overall traffic planning, prioritizing main road vehicles helps maintain dynamic road balance. Think about it: road paving vehicles operate in fixed locations, move slowly, and can only pave a few meters per hour at most; whereas main road traffic flows quickly, with dozens of vehicles potentially passing by every minute. If the order were forcibly reversed, the economic losses caused by congestion would be significant. I've participated in road coordination meetings where dispatchers explicitly require construction vehicles to avoid interrupting traffic flow unless absolutely necessary. In practice, paving vehicles often work late at night or divert traffic in advance to specifically avoid competing with main road vehicles. Essentially, this is about optimizing resource allocation, allowing fewer but critical tasks to yield to high-frequency demands. Just like hospitals prioritize emergency cases for critical patients, the road network must also prioritize serving the majority of road users.
