Memory tips

How to study them (our advice, not official rules):

  • Learn the number with its unit and its place. “15 feet from a hydrant” sticks; “15” on its own gets mixed up with 15 mph.
  • Say the answer before you look. Recalling the number yourself is harder than spotting it among four options, and it is what makes it stick.
  • Come back to the ones you miss. The quiz above brings missed questions back more often. Short rounds over several days beat one long session.

Questions about the numbers

What numbers do I need to know for the Tennessee permit test?

Mostly distances (how close you may park to a hydrant or crosswalk, when to signal, when to dim your high beams), speed limits, blood-alcohol limits, and the ages, hours and deadlines for your permit and license. This page lists 76 of them for Tennessee, each with its source.

Why focus on numbers?

A California DMV study of its own knowledge test found that many of the hardest questions “are numerical and have correct answers that must be learned by rote memorization.” Numbers are easy to mix up under pressure, so they are worth drilling on their own.

Where do these numbers come from?

Each one is quoted from the Tennessee Comprehensive Driver License Manual, Tennessee statutes or TDOSHS pages. Our build checks that every number on this page appears word for word in the quote it cites.

Is the numbers drill free?

Yes. The table and the numbers quiz are free and unlimited, and so are the first 20 flashcards.
