Which ASVAB section tests understanding of automotive concepts?

The section that tests understanding of automotive concepts is Automotive and Shop Information. This specific section is designed to evaluate a candidate's familiarity with automotive systems, tools, and shop practices associated with vehicle maintenance and repair. It covers topics such as the operation of engines, electrical systems, and the various components involved in automotive work, providing a comprehensive assessment of one's knowledge in areas critical to automotive fields.

The other sections, while important for different skills, do not focus specifically on automotive concepts. Mathematics Knowledge assesses numerical problem-solving abilities, General Science evaluates understanding of basic scientific principles, and Paragraph Comprehension measures reading and interpretative skills, all of which are unrelated to automotive mechanics or shop information.
