What does a flashing yellow light mean at an intersection for commercial vehicles?

A flashing yellow light at an intersection serves as a warning signal that indicates drivers, including those operating commercial vehicles, should proceed with caution. It alerts drivers to potential hazards or the need to be aware of other vehicles or pedestrians. Instead of stopping, the flashing yellow light suggests that it is safe to continue, but the driver must be vigilant and ready to react to any unforeseen circumstances.

In the context of commercial driving, which often involves larger vehicles with longer stopping distances, being cautious means assessing the intersection thoroughly, checking for other traffic, and ensuring it is safe to proceed before doing so. This understanding is crucial, as commercial drivers have a higher responsibility due to the size and weight of their vehicles. The other options do not accurately reflect the appropriate action for a flashing yellow light, as a complete stop is not required, nor is it advisable to increase speed or wait for a green light in this situation.
