Who we are
Yield & Go is independently operated. We publish free practice tests and study pages for the car permit, motorcycle and commercial driver's license (CDL) knowledge tests in every state. We aren't a government agency or a DMV, and our questions aren't the official test: they're practice material written to help you learn your state's handbook.
The sources we use
Every page names its source, and every handbook page we cite links to the official file.
- Your state's official handbook. Every question comes from the state's driver handbook, motorcycle manual or CDL manual, and records the chapter, section and printed page it comes from. We link to the official file and never host a copy.
- Official state agency pages. Where a handbook leaves something out or is out of date (how to apply for a permit, what to bring, the size of the test), our state FAQs and permit guides use the licensing agency's own website and link to the page used.
- National standards, for what's the same everywhere. When a state's handbook doesn't show a road sign, the sign's meaning comes from the federal Manual on Uniform Traffic Control Devices (MUTCD), which every state follows. General riding skills a state's motorcycle manual leaves out come from the Motorcycle Safety Foundation's Motorcycle Operator Manual. Federal CDL rules come from the Code of Federal Regulations and the FMCSA, as set out on our federal CDL rules page. Those questions say which source they use.
We never add a state law, fee, age limit or number that its official sources don't give. Fees change often, so we say when a fee applies and link to the agency instead of quoting a price.
How a question is written
- One rule, in our own words. Each question tests one rule from the handbook, written in plain English. States don't publish their real test questions, and we don't claim to have them.
- Asked in more than one way. A rule is asked a few different ways, including as a real situation on the road, so learning it means understanding it, not remembering one wording.
- Four answers, all believable. Wrong answers are mistakes a learner could really make, never jokes, and we don't use "all of the above" or "none of the above".
- Every answer explained. The explanation gives the rule, why it matters and how it applies to a related case, then the handbook page to read.
- Pictures drawn for the question. Road signs follow the federal sign designs, and road scenes show the situation without giving the answer away.
- One question per situation in a test. When two rules describe the same situation, a single test asks only one of them, so no test repeats itself.
How every question is checked
Before a question reaches the site, it goes through the same five steps in every state.
Written from the official handbook
We write each rule in our own words and record the chapter, section and printed page it comes from, with the handbook's exact wording kept for checking.
Checked against the page
A second check compares every rule with the wording on its handbook page. Anything the page doesn't say goes back to be rewritten or is left out.
Approved before it goes live
Only approved questions reach the site. Drafts and questions waiting for review are never shown.
In our own words
An automatic check stops any question, answer or explanation that repeats 10 or more words in a row from the handbook.
Kept up to date
Every week we check whether each state has published a new handbook. When one appears, every rule is compared with the new edition, and the ones that changed are reviewed again.
Keeping up with new handbooks
When the weekly check in step 5 finds a new edition, rules whose text didn't change stay on the site with the new edition's page numbers. Rules that changed go back through steps 2 and 3, and only return once they match the new text. The edition each state's questions are written from is named on that state's page. New editions we've checked and other changes are listed on our What's new page.
This takes time; what that means for your answers is on our Disclaimer.
Reporting and correcting mistakes
Every answer has a "Report a problem with this question" link, after you check it in practice and in the answer review after a test. Pick what's wrong and add a note if you like: we know which question it was without you having to describe it. For anything else, or to get a reply, use our contact form.
We check every report against the handbook page the question cites. If we were wrong, we correct the question or take it off the site. If the answer is right but the question was confusing, we make the wording or the explanation clearer.
Independence and advertising
What we write depends only on the official sources above. No one pays to be included or to change a question. If you see ads on the site, they're marked "Advertisement" and kept apart from questions, answers and buttons, so an ad can't be mistaken for part of a test.
