Teenagers between the ages of 15 and 17 can take the DMV written test online under the supervision of a parent or legal guardian registered on the PID (Proctor Identification) App. Alternatively, it is possible to schedule an appointment for permit tests at a Tennessee driver services center. First-time applicants should complete the application before visiting the center.

You can make up to 6 mistakes on the Tennessee DMV written test. To pass, you need to answer at least 24 questions correctly, achieving an 80% accuracy rate. Take your time to read each question accurately.
If you have a learner permit:
  • You must drive with a licensed driver aged 21 or older seated in the front seat.
  • Driving between the hours of 10 p.m. and 6 a.m. is not permitted.

If you have an intermediate restricted license:
