What test must be passed to obtain a learner’s permit in Indiana?

Answer: B — The written knowledge test

To obtain a learner’s permit in Indiana, one must pass the written knowledge test. This test assesses an individual's understanding of traffic laws, road signs, and safe driving practices, which are crucial for operating a vehicle safely. The knowledge gained from this test serves as a foundation for responsible driving behavior while the learner is operating the vehicle under supervision, preparing them for the next steps toward obtaining a full driver's license. The other options, while related to the overall process of becoming a licensed driver, do not pertain specifically to the initial requirement for obtaining a learner's permit. The driving skills test and practical driving test are required to gain a full driver’s license after the learner's permit phase is finished. The vision test is typically a standard procedure to ensure all drivers meet basic sight requirements but is not the primary assessment for obtaining a learner's permit.
