What is the primary function of yield signs in traffic control?

Yield signs are a crucial component of traffic control systems designed to manage the flow of vehicles at intersections and other roadways. The primary function of yield signs is to instruct drivers to yield the right-of-way to other vehicles or pedestrians. This means that when a driver approaches a yield sign, they must slow down and be prepared to stop if necessary, allowing other road users to proceed safely.

This traffic control mechanism helps prevent collisions by ensuring that vehicles do not enter an intersection or merge into traffic without first checking whether it is safe to do so. The yield sign communicates an important rule: when in doubt, give way to others, which promotes safety and smooth traffic flow. Understanding this function is critical for drivers to navigate intersections and meet the needs of other road users effectively.
