Take our free Northern Territory Heavy Rigid Knowledge Test! Each free heavy rigid vehicle practice test contains randomized rule and sign driving test questions taken from a comprehensive database of NT 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 Northern Territory Motor Vehicle Registry. To pass the official test, you need to score at least 26 out of 30. 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!
