In California, what is the minimum age to be issued an unrestricted driver license?

Answer: B — 16

In California, the minimum age requirement for an unrestricted driver's license is 16. This is because at age 16, a person can obtain a provisional driver's license which allows them to drive unsupervised with certain restrictions. Option A (age 15) is incorrect because at this age, a person can only obtain a learner's permit, which requires a licensed adult to be present in the car at all times. Option C (age 17) and D (age 18) are incorrect because at these ages, a person can also get a provisional driver's license but without any restrictions. Therefore, the minimum age for an unrestricted driver's license in California is 16 years old.
