How should a driver react upon encountering a flashing yellow light?

When a driver encounters a flashing yellow light, the appropriate reaction is to slow down and prepare to stop. The flashing yellow light serves as a caution signal, indicating that the driver should be alert and ready for potential hazards ahead.

This warning could suggest various situations, such as upcoming intersections with cross traffic, pedestrian crossings, or potential road work zones. By slowing down, the driver can assess the conditions more carefully and make informed decisions about their next actions.

In contrast, proceeding without any change in speed would be unsafe, as it could lead to missed hazards that require a more cautious approach. Stopping completely is unnecessary and could disrupt the flow of traffic unless a clear stop signal is presented. Finally, changing lanes immediately can create confusion and increase the risk of collisions, especially if other vehicles are approaching or if the lane change is not warranted. Thus, reducing speed and preparing to stop is the safest and most responsible reaction to a flashing yellow light.
