How the test is scored
Online or in person: two ways to take the test
Both versions have the same 25 questions in English or Spanish and the same 80 percent passing score. The difference is where you sit, what you need, and what it costs.

Who has to take the written test
Anyone getting a first Nevada license or instruction permit takes it, along with some drivers moving here from another state and anyone whose license lapsed for more than a year.
Teens can take the test from 15½ as part of getting a permit, with extra forms from school and a parent. Our Nevada learners permit guide lists every document and fee.
If you’ve never held a U.S. license, or yours has been expired, suspended or revoked for more than a year, you’ll take the vision, knowledge and skills tests. Renewing an expired Nevada license instead? See the late-renewal rules.
Most drivers 21 and older with a valid U.S. license skip it. Our new to Nevada guide has a checker for when the test applies.
Written test fees, the vision test, and retakes
Vision test: everyone takes a free vision screening. You need 20/40 for full privileges. If you need glasses or contacts to get there, your license carries a corrective lens restriction.
If you don’t pass: you can retake the test the next day, or after 24 hours if you were disqualified. A passing result stays valid for one year.
The DMV’s $25 testing fee covers your first skills test too. Once you hold your permit, see our Las Vegas drive test guide for the road test.
How to study for the knowledge test
Study the Nevada Driver’s Handbook, which the DMV offers free to read or download.
The DMV posts an official practice quiz, so you can see the question style before the real thing.
Online, make sure your computer’s camera works and you have an hour free before you start.
Need an interpreter? For the written test you can bring an interpreter approved by a government agency, court, school or nonprofit advocacy group, with that group’s letter and form DLD 11 at each test. Family members can’t interpret, and you pay the interpreter’s cost.
