Under what circumstance would a driver in Massachusetts be required to wear corrective lenses while driving?

Answer: B — If their license has a restriction code for corrective lenses

A driver in Massachusetts is required to wear corrective lenses while driving if their license has a restriction code for corrective lenses. This means that during the licensing process, if it has been determined that they cannot see adequately without corrective lenses, the state will impose a restriction that mandates the use of those lenses when operating a vehicle. This rule is in place to ensure the safety of the driver and others on the road. Drivers who require corrective lenses must adhere to this restriction to maintain optimal vision while driving, which is crucial for activities such as reading road signs, recognizing the speed of other vehicles, and detecting pedestrians. The other choices do not reflect the legal requirements for driving in Massachusetts regarding corrective lenses. Simply wanting to wear them, only wearing them during night driving, or an age-based criterion does not establish a legal mandate or a necessary condition for safe driving.
