What mirrors should a driver particularly concentrate on when making a left-hand turn?

When making a left-hand turn, it is crucial for a driver to primarily focus on the interior mirror and the left exterior mirror. The interior mirror provides a view of the traffic behind the vehicle, which helps the driver assess the overall situation before initiating the turn. The left exterior mirror is particularly important as it gives visibility to the left side of the vehicle, including cyclists, pedestrians, and any obstacles that may be present in that lane or intersection.

This focus is essential for ensuring safety; it allows the driver to check for any oncoming traffic or hazards that might come from the left side while completing the turn. By using these mirrors together, the driver can get a comprehensive understanding of their surroundings, which is critical for safe maneuvering during a left turn.

Depending on the other combinations given, they may not adequately cover the necessary checks required for safely executing a left-hand turn, making the selected mirrors the most effective choice for this driving maneuver.
