Final answer:
Drivers are often required to yield to public transit buses when they are signaling to re-enter traffic with a yield sign on the back; this improves pedestrian safety and helps public transportation move efficiently. Local traffic laws provide specific guidelines.
Step-by-step explanation:
The question of when you are required to yield to a public transit bus that has a yield sign on the back and is signaling to enter traffic is related to traffic laws, which can vary depending on the location. Typically, laws require drivers to yield to transit buses in certain situations to improve pedestrian safety and transit efficiency. While the specific rules can differ, a common regulation is that if the transit bus is re-entering traffic from a designated stop and has the yield sign illuminated, you must yield to the bus. This policy aids in reducing the potential for accidents and ensures the timely movement of public transportation. It is essential to check your local traffic laws to understand the exact requirements for yielding to buses.
