What can drivers who have limited ability to turn their heads use for assistance?

Drivers who have limited ability to turn their heads can benefit significantly from the use of extra large mirrors. These mirrors are designed to provide a wider field of view, which helps in covering blind spots that might not be visible through standard mirrors. This is particularly important for drivers with limited mobility in their necks, as it reduces the need to turn the head to check for vehicles or obstacles in adjacent lanes.

Having larger mirrors can enhance safety by allowing drivers to maintain situational awareness without the need for extensive head movement, thus enabling them to drive more confidently and safely. The other options, while potentially helpful in various scenarios, do not specifically address the limitation of head turning the same way that extra large mirrors do.
