What does a flashing yellow light mean for a motorcycle rider?

A flashing yellow light indicates to a motorcycle rider to proceed with caution. This means that while the light does not require the rider to stop, it serves as a warning to be alert and careful about potential hazards. Motorcyclists should scan the area for other vehicles, pedestrians, or unexpected obstacles that may not be immediately visible. It encourages a more vigilant and defensive approach to riding, ensuring safety in situations where there may be cross traffic or changes in road conditions.

The other options do not accurately reflect the meaning of a flashing yellow light. Stopping immediately would be inappropriate, as this light signifies a warning rather than a requirement to halt. Speeding up to clear the intersection could lead to dangerous situations, particularly if other vehicles might be crossing or if conditions are not safe. Yielding to other vehicles, while sometimes necessary, is not a directive given by a flashing yellow light itself; it emphasizes caution but doesn't instruct riders to give way to oncoming traffic.
