Final answer:
A person with sight in one eye must read 20/40 on a Snellen chart to get a driver's license, although standards can vary by region.
Explanation:
The question concerns the visual acuity requirements for obtaining a driver's license for a person with sight in only one eye. In many regions, to compensate for the loss of vision in one eye, individuals must meet a stricter standard compared to those with vision in both eyes. While the standards can vary by jurisdiction, a common requirement for people with vision in only one eye to obtain a driver's license is reading at least 20/40 on a Snellen chart. This means that what a person with one eye can see at 20 feet, a person with typical vision can see at 40 feet. It's important to verify with local regulations, as these can vary.
