Maintaining good driving visibility is crucial for safe driving, and regularly checking and cleaning mirrors and windows plays a vital role in this. When mirrors and windows are clean and properly adjusted, they provide clearer and unobstructed views of the surrounding environment, which helps in detecting other vehicles, pedestrians, and possible hazards. Dirty or improperly positioned mirrors can lead to blind spots or missed signals, increasing the risk of accidents.

Regular cleaning helps to remove dirt, grime, and other obstructions that can impair visibility. Furthermore, checking the mirrors to ensure they are correctly aligned allows drivers to see a broader view of the road and what is behind them, which is especially important for maneuvers such as changing lanes or merging.

The other options, while addressing aspects of driving safety, do not directly relate to visibility in the same essential way. For example, using high-beam headlights at all times can create glare for other drivers and is not advisable in every situation. Driving without distractions is crucial for focus, but it does not specifically address visibility. Lastly, keeping window tint within legal limits is important for safety and compliance but is not a direct factor in maintaining visibility compared to cleaning and adjusting mirrors and windows.
