All students must pass the State Knowledge Test on traffic laws, rules and regulations by scoring at least an 80% on a 50-question test. Hickory Driving School’s Practice Knowledge Test is used in conjunction with the NJMVC Driver’s Manual. Do not bring any copies into a NJDMV or into Hickory Driving School’s office. The database consists of 140 different questions and allows the student to choose as many as they would like to complete at a time. The score and answers will be shown at the end of the test.
