The written and practical exams for a learner's permit are different in each state. Individual states can have specific road laws and the exams reflect this.
While the exams vary by state, they are relatively similar. Written exams include questions regarding safe driving and traffic signs, which are national standards. A practical exam generally consists of two parts: a basic maneuver course and an on-the-road evaluation, both designed to assess knowledge and safe driving capabilities.
The examiner also evaluates the vehicle in which the driver takes the practical exam, and the examiner usually asks the driver to show familiarity with the components of the car, such as turning the windshield wipers on and off.
