A flashing yellow arrow traffic signal is an indication that you may proceed with caution in the direction indicated by the arrow. It means that the turn is permitted, but you must be alert for oncoming traffic and pedestrians. Drivers should slow down and assess the situation before making the turn; this ensures safety for everyone involved.

While it is essential to be cautious, you do not need to stop unless it's necessary for safety reasons or if there are vehicles or pedestrians in your path. The signal suggests that it's okay to continue, but maintaining awareness is crucial. The option to accelerate through the intersection is inappropriate, as doing so may lead to dangerous situations if other vehicles or pedestrians have not cleared the area. Yielding to oncoming traffic is also important, but the flashing yellow arrow is mainly an indication to proceed with caution rather than to yield, unless it's required by the circumstances.
