Which action can help improve visibility around large vehicles?

Keeping mirrors cleared and positioned properly is essential for improving visibility around large vehicles. Properly adjusted mirrors allow drivers to have a clear view of the blind spots that are often present with larger vehicles like trucks and buses. These types of vehicles have substantial blind areas, making it difficult for drivers to see other road users, especially smaller vehicles, bicycles, and pedestrians.

By ensuring that mirrors are not obstructed by dirt, snow, or ice and that they are positioned to give the best possible view of surrounding traffic, drivers can significantly enhance their awareness of their environment. This proactive approach helps in effectively navigating around large vehicles; for instance, it aids in safe lane changes or merging, ultimately leading to a decrease in the likelihood of accidents.

In contrast, using high beam headlights at all times can create visibility issues for other drivers and may not necessarily improve one’s own visibility around large vehicles. Maintaining less than 10 feet of distance can be unsafe, as large vehicles require more space for maneuvering and stopping. Driving alongside a truck can also put a driver in a risky situation due to potential blind spots and limited visibility into the truck's intentions. Thus, the best practice for improving visibility is through the proper maintenance and adjustment of mirrors.
