Tennessee Permit Practice Test

A traffic signal with a yellow left arrow indicates that the protected left turn is about to end and the driver should prepare to yield to oncoming traffic. This means that the driver should be cautious and ready to stop if necessary, or proceed with their turn if there is no oncoming traffic. Option D is incorrect as it does not relate to traffic signals or driving. Option A is not the complete answer as it only mentions one aspect of the purpose of a yellow left arrow signal. Option B is incorrect as it is not the full answer and only mentions what is about to happen, not what the driver should do in response. Therefore, the correct answer is C, as it contains both aspects of the purpose of the yellow left arrow signal.
