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

When making a left-hand turn, a driver should particularly concentrate on the interior and left exterior mirrors to ensure a safe maneuver. The interior mirror provides a view of what is happening directly behind the vehicle, allowing the driver to monitor the traffic flow and any potential hazards that may be approaching from behind. The left exterior mirror, specifically, offers a critical perspective of the area to the driver's left, which is especially important when turning left, as this is where pedestrians, cyclists, or other vehicles may be present in a blind spot.

By focusing on these two mirrors, the driver can be more aware of any obstacles that could pose a risk during the turn. This practice enhances situational awareness and is crucial for making informed decisions, helping to prevent accidents during the maneuver. Other mirror combinations would not provide the same level of visibility regarding the immediate surroundings on the left side, where potential hazards are greatest during a left-hand turn.
