What does a flashing yellow traffic signal indicate?

A flashing yellow traffic signal indicates that drivers should proceed with caution. This means that while the signal does not require them to stop, they should be alert and prepared to react to any potential hazards or other vehicles in the intersection. It is a warning that conditions may require slowing down or being extra careful.

In contrast, a solid red light would require a complete stop, while a green light indicates that it is safe to proceed without hesitation. Other signals, like a yield sign, require yielding to pedestrians or other traffic but may not involve taking caution in the same way that a flashing yellow does. Understanding the meaning of traffic signals is crucial for safe driving and navigation on the road.
