A flashing red light at an intersection means what?

A flashing red light at an intersection indicates that drivers must come to a complete stop, just as they would at a stop sign. This rule requires the driver to assess the situation and proceed only when it is safe to do so, ensuring that they yield to any oncoming traffic or pedestrians before moving forward. The emphasis here is on stopping fully to ensure that all safety measures are taken.

The other choices misinterpret the instructions associated with a flashing red light. While proceeding with caution is important in driving, it does not capture the necessity to stop fully before proceeding. Similarly, yielding to pedestrians, while a crucial part of driving, does not encompass the requirement to stop at a flashing red light. Preparing to make a turn is also irrelevant in the context of a flashing red light, as the primary action required is to stop first.
