What is the primary purpose of a learner's permit?

The primary purpose of a learner's permit is to allow new drivers to practice driving under supervision. This permit is specifically designed for individuals who are just beginning to learn how to operate a vehicle safely. With a learner's permit, new drivers are required to drive with a licensed adult in the vehicle, which provides a structured and safe environment to gain practical experience and learn road rules.

While the other options mention aspects related to driving and testing, they do not capture the essence of what a learner's permit is intended for. Driving without restrictions is applicable to individuals with a full license, not a learner's permit, which is intended to be a transitional stage in the licensing process. Taking the written test is usually a prerequisite to obtaining a learner’s permit, but it is not the main purpose of having one. Similarly, while a learner's permit may serve as an identification tool, its primary function is to facilitate supervised driving practice for new drivers, ensuring they build the necessary skills and knowledge before obtaining a full driver's license.
