Answer :
Final answer:
The sign on a transit bus signaling to enter traffic means other drivers should yield. This is part of traffic safety measures optimized by engineers, such as the yellow time at traffic lights.
Explanation:
When a transit bus is signaling to enter traffic, the sign means that other drivers should yield. This means you should slow down or stop if necessary to let the bus merge into traffic. It's critical for safety on roads, especially in scenarios where traffic engineers have optimized signals, such as the yellow time at intersections, to minimize what is known as the "no-win" zone. Paying attention to such signals and yielding to buses ensures smoother traffic flow and enhances safety for all road users, including drivers, transit users, and pedestrians.
