When making a turn, especially in larger vehicles that have a significant tail-swing, it is important to be aware of the space occupied by the rear of the vehicle. The opposite mirror gives insight into how much clearance there is on that side, informing the driver whether it is safe to proceed with the turn.

Checking the blind spot is also important, but it may not offer as comprehensive a view as the opposite mirror when it comes to rear clearance during a turn. The side window provides visibility but does not replace the need for utilizing the mirrors, which are designed specifically for situ
