What is the main function of a yield sign?

The main function of a yield sign is to indicate to drivers that they should slow down and yield to oncoming traffic or pedestrians. When approaching a yield sign, a driver must be prepared to stop if necessary and give the right of way to any vehicles or individuals that have priority on the road. This is a crucial aspect of road safety, ensuring that traffic can flow smoothly and safely at intersections or when merging with moving traffic. The yield sign serves to alert drivers to be vigilant and attentive to their surroundings, preventing potential collisions and maintaining order on the road.
