What is one way to enhance safety during lane changes for large vehicles?

Enhancing safety during lane changes for large vehicles is crucial due to their size and limited visibility. The correct approach involves carefully checking all mirrors and blind spots. This method helps to ensure that the driver is aware of their surroundings, including any vehicles that may be in adjoining lanes or in the blind spots that are not visible through mirrors alone. Since large vehicles have larger blind spots, this comprehensive check reduces the risk of collisions during lane changes.

Choosing only one mirror, making lane changes without signaling, or speeding up before changing lanes would compromise safety. These actions may overlook critical information about nearby vehicles and fail to communicate intentions to other drivers, thereby increasing the likelihood of accidents.
