If you fail the HI Driving Exam, you will not receive your HI Driver's License. You will be able to retake the exam after a week has passed, however, you should not rush retaking the HI Driving Exam after you have failed. You should pay attention to what your examiner indicates as your weaknesses, and you should work upon improving your driving skills before you retake the HI Driving Exam.
