Take our free South Australia Driver Knowledge Test! Each free car practice test contains randomized rule and sign driving test questions taken from a comprehensive database of SA test-specific questions. These questions are based on the official driver handbook, so that the questions most closely mirror the actual driving test, administered by the South Australia Transport SA. To pass the official test, you need to score at least 40 out of 50. Please note that each time you take a test on our website, you will get a different set of randomized questions, creating an excellent learning experience so we can prepare you to pass your test. Good luck and please let us know if you come across any questions on the actual test that stump you! Happy driving!
