At what age can you apply for a renewal of a provisional license?

Answer: C — 17 years old

To apply for a renewal of a provisional license in California, the applicant must be at least 17 years old. This aligns with state regulations that stipulate the transition from a provisional license to a full, unrestricted license usually occurs at age 18. The purpose of the provisional license is to allow new drivers to gain experience while still under certain restrictions, which are removed once they reach the required age and meet the necessary conditions for renewal. Thus, being 17 signifies that the driver is close to reaching that full licensing age.
