A solid red traffic light indicates that drivers must come to a complete stop and are not allowed to proceed until the light turns green. This rule is crucial for maintaining safety on the road, as it clearly communicates to all road users that they must halt their movement to prevent accidents at intersections.

When the traffic light is red, it helps manage the flow of traffic by ensuring that vehicles and pedestrians wait their turn to proceed. This clear directive helps prevent collisions that can occur if vehicles attempt to move while the light is red. In addition, stopping at a red light gives drivers the opportunity to observe their surroundings and ensure it is safe to continue once the light changes.

The other options suggest actions like slowing down, proceeding if clear, or yielding, which do not align with the explicit requirement to stop at a solid red light, thereby compromising the safety protocols designed to regulate traffic at intersections. Understanding these signals and their meanings is vital for any bus driver, as bus safety significantly impacts not only the passengers on board but also other road users.
