Take our free Ontario A Driving Test! Each free semi-trailer truck (4.600kg < x < 11.000kg) practice test contains randomized rule and sign driving test questions taken from a comprehensive database of ON 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 Ontario Ministry of Transportation. To pass the official test, you need to score at least 20 out of 25. 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!
