At what age can an individual with a Learner's Permit drive alone?

Answer: B — 16

A Learner's Permit typically allows an individual to start learning how to drive, as long as they are accompanied by an adult who has a valid driver's license. At age 16, depending on the state, an individual may be eligible to drive alone with a Learner's Permit. Option A is incorrect because 15 is generally too young to receive a Learner's Permit. Option C is incorrect because while some states allow individuals to obtain their Learner's Permit at age 17, they may still require supervision while driving. Option D is incorrect because 18 is the age at which an individual can typically obtain a regular driver's license without any restrictions.
