What does a flashing yellow light typically indicate to drivers?

A flashing yellow light serves as an important signal to drivers, indicating that they should proceed with caution. This warning alerts drivers to be aware of their surroundings and to be prepared to encounter potential hazards or changes in traffic conditions. It conveys that while they may continue driving, they should reduce their speed and be vigilant, as there may be pedestrians crossing or other vehicles that could pose a danger.

The other options suggest actions that would be inappropriate or unsafe in the presence of a flashing yellow light. For example, stopping immediately could lead to confusion and possibly create an unsafe situation for the driver and others on the road. Making a U-turn is not advisable under these circumstances, as it may disrupt the flow of traffic. Speeding up is also dangerous, as it goes against the cautionary intent of the signal that encourages drivers to be more aware and careful.
