What is the correct action when turning at an intersection?

Answer: B — Always signal before turning

When turning at an intersection, always signaling before making the turn is crucial for safety and effective communication with other road users. Signaling informs other drivers, cyclists, and pedestrians of your intended actions, allowing them to anticipate your movements and adjust accordingly. This practice helps prevent accidents by promoting clarity and understanding on the road. Signaling not only provides an indication of your next move but also is a legal requirement in many jurisdictions, reflecting good driving etiquette and responsibility. It enhances overall road safety by reducing the likelihood of misunderstandings between road users. In the context of the other options, yielding to oncoming traffic from the left is important but primarily applies in specific scenarios, such as when making a left turn at an intersection, and isn't the primary action to take. Waiting for a clear signal usually pertains to traffic lights rather than the general action of turning, while turning without signaling can lead to confusion and potential accidents. Thus, signaling stands out as the most critical and responsible action when turning at an intersection.
