Some drivers are legally required to wear what while driving?

The correct answer highlights a significant safety requirement for certain drivers. Individuals who have vision impairments or were issued a restriction on their driver’s license are mandated to wear corrective lenses, such as contacts or glasses, while operating a vehicle. This requirement ensures that the driver has the necessary vision to safely navigate the roads, thus reducing the risk of accidents.

While the other options may touch upon various personal choices or preferences for driving, they do not carry legal significance in the same way that the requirement for corrective lenses does. Hats, fragrance, and sunglasses do not influence driving safety directly; instead, they are either optional for personal comfort or style and do not serve a critical role in ensuring the driver's ability to see clearly while driving.
