What should a driver do if they see a yellow arrow and are unsure about the action required?

When encountering a yellow arrow, it serves as a warning that the signal is about to change, indicating that drivers should prepare to yield or make a decision regarding their next move. If a driver feels uncertain about what action to take, stopping and assessing the situation is the most prudent choice. This allows the driver to evaluate their surroundings, take note of oncoming traffic, pedestrians, and any other obstacles before proceeding.

Stopping ensures safety by allowing enough time to make an informed decision rather than acting impulsively when unsure. In contrast, turning anyway without certainty may lead to a dangerous situation, as it could endanger the driver and others on the road. Proceeding with caution can also be risky if the driver is unsure, as it might lead to confusion or accidents. Looking to another driver for guidance may not be a reliable measure since they might also be unsure or make the wrong decision. Therefore, stopping to assess the situation is the appropriate response to ensure personal safety and that of others on the road.
