What action should a driver take when approaching a traffic signal that is yellow and flashing?

Answer: B — Prepare to stop and proceed with caution

When a driver encounters a traffic signal that is yellow and flashing, the appropriate action is to prepare to stop and proceed with caution. A yellow flashing light is an indication that drivers should be alert and ready to navigate the intersection carefully. It serves as a warning that there may be potential hazards or that cross traffic might have the right of way. In this situation, approaching the intersection cautiously allows the driver to assess the conditions, ensuring they can respond appropriately if other vehicles or pedestrians are present. While it is advisable to proceed with caution, the key aspect of the yellow flashing signal is to be prepared to stop if necessary, as the signal does not grant the same level of clearance as a green light. The other options, such as speeding up to clear the intersection, ignoring the signal, or turning around, would not be safe actions. Speeding can increase the risk of accidents, ignoring the signal puts the driver and others at risk, and turning around is generally not practical and could also create hazardous situations in traffic. It is essential to follow traffic signals and markings to maintain safety and order on the roads.
