What should you do when you see a flashing yellow light at an intersection?

When you see a flashing yellow light at an intersection, the appropriate action is to slow down and cross the intersection carefully. A flashing yellow light indicates that drivers should proceed with caution, as it alerts them that there may be other vehicles or pedestrians present or that the intersection requires careful navigation.

By slowing down, you allow yourself enough time to assess the situation at the intersection and make safer driving decisions, which is crucial for preventing accidents. It's important to remain vigilant and be prepared to yield to any other roadway users that may not be as visible.

The other options involve actions that could lead to unsafe conditions. Speeding up could put you at risk of missing important visual cues about traffic or pedestrians. Coming to a complete stop is unnecessary unless there is a sign indicating to do so, and changing lanes might not be safe or legal, especially if other vehicles are present. Therefore, the best practice is to approach the intersection slowly and carefully, ensuring safety for yourself and others.
