Final answer:
A yield sign is similar to a stop sign but allows a driver to proceed without a full stop if safe to do so, promoting both traffic flow and safety.
Step-by-step explanation:
The traffic control device that means the same as stop signs except you may proceed without coming to a full stop if it is safe to do so is known as a yield sign. Unlike a stop sign where vehicles must come to a complete stop, the yield sign indicates that the driver must slow down and only stop if necessary to let other traffic pass before proceeding when safe.
The purpose of these signs is to keep traffic flowing smoothly while still ensuring safety at intersections particularly considering the risks to pedestrians and the propensity for vehicles to exceed speed limits.
