About these questions
We wrote these practice questions from the facts in the South Carolina Driver's Manual (Edition linked from SCDMV's Beginner's Permit page; no revision date is printed (the cover page of the 06/2024 edition is gone) and the file was last modified 2026-04-01 (server date), read 2026-11-09. Compared with the 06/2024 edition it adds the South Carolina Hands-Free and Distracted Driving Act (pp. 3-4 to 3-5), a 30-day permit holding period for applicants 18 or older (p. 1-5) and shorter route-restricted license lists; the rest of the text is the same, with some pages shifted. Pages are cited as printed (section-page, e.g. 1-4) with the PDF page. Where the manual gives no value, the South Carolina Code of Laws, Title 56, Chapter 5 (scstatehouse.gov, read 2026-11-09) and SCDMV web pages are the source. edition) and from official sources on road signs. Every answer links to its source, so you can check it and read more.
