Which of the following is a common distraction that can affect driving?

Talking to passengers is a common distraction that can significantly impact a driver's focus on the road. Engaging in conversation might lead to divided attention, especially if the discussion becomes animated or if the passengers are expressing strong emotions. This can prevent the driver from being fully attentive to their surroundings, including other vehicles, pedestrians, and traffic signals.

In contrast, adjusting mirrors is generally considered a routine action that most drivers perform before or at the beginning of a trip, making it less of a distraction if done safely. Wearing sunglasses can enhance visibility and reduce glare, contributing positively to safe driving rather than distracting from it. Checking tire pressure is a maintenance task that is usually performed before driving, rather than while on the road, thus avoiding any distraction during the act of driving itself.
