Is there a CDL practice test for people who are still learning English?

Yes, you can practice with any plain-English test if you use the W and K method: mark each miss as a word you did not know or a rule you did not know. Fix the words first, then the rules.

How many questions can I miss on the CDL written test?

The federal rule requires at least 80 percent correct on each knowledge test, so multiply your test's question count by 0.20 and round down. For a 50-question test, that is 10 (example only). Use your own state's question count.

Why do some answers look right but get marked wrong?

Often one answer is more complete than the other. Look for words like all, only, always, never and except, and pick the answer that is true every time.

How many new words should I learn each day?

Ten a day is a workable pace with the manual open: 30 words in 3 days and 70 in 7 days. Study in blocks of 20 to 30 minutes so you do not miss small words when you are tired.

Is 80 percent on a practice test enough to book?

Not by itself. A score right on the line leaves no room for a tired day, so wait until your last two tests are above 80 percent and your word misses are going down.

CDL Practice Test for Non-Native English Speakers

Q: Can I take the CDL test in another language?

It depends on your state. Ask your state licensing office or read your state's CDL manual before you book.

To practice for the CDL permit test in English, take short timed tests, find the key word in each question, say the question again in your own simple words, and check every miss in your state's CDL manual. By the end of this page you will have a miss log that shows whether you need more words or more rules, and a passing-math note that tells you when to book.

Mark every miss as W or K before you do anything else

Not every wrong answer means the same thing. Some mean you did not know a word. Others mean you knew the words but not the rule. Treat them differently.

After each practice test, write one letter next to every miss:

Letter	What happened	What to do
W	You did not know a word in the question or the answers	Add the word to your word list. Do not count it as a topic you failed.
K	You understood every word but picked the wrong answer	Open the manual to that section. Re-drill it in 1, 3 and 7 days.

Here is the rule: if 3 or more of every 10 misses are W, spend your next session on words, not on more tests. If K is the bigger group, go back to the manual. This is a study rule of thumb, not a published standard, but it stops you from re-reading rules you already know.

Read each question in five steps

Slow reading beats fast guessing. Use the same five steps every time, even on questions that look short.

Read the question once with the answers covered.
Underline the key word: all, only, except, not, first, most, never, always.
Say the question in your own short words.
Read every answer before you pick. Cross out any answer that is clearly wrong.
After the test, read the manual section for every miss, not only the right letter.

Example of step 3: the question says, "Which of the following is NOT a reason to check your brakes?" In your own words: "Three are reasons. One is not. Find that one." Now you know what you are looking for before you read the answers.

Learn the words that repeat before you take more tests

The same trucking words come back again and again. If you do not know them, you will miss questions you could have answered. A 2026 U.S. Department of Labor advisory points to trucking and transportation vocabulary, including safety and regulatory terms, as the base for English-language training for drivers. Start there.

Keep your manual open and add 10 words a day. Example: at 10 words a day, you have 30 words after 3 days and 70 after 7 days. Use this three-column list:

Word	Plain meaning	Where in the manual
gross weight (example row)	total weight of the truck and the load	General Knowledge section

Start with the topics that show up in General Knowledge. One legal aid overview lists following distance, space management, braking and cargo safety as core topics. The exact content differs by state, so use your state's manual as the final word.

Study in blocks of 20 to 30 minutes. Tired readers miss small words, and small words decide these questions.

Two answers look right? Pick the more complete one

This is the most common trap. Two answers both sound correct. One of them leaves something out.

Look for these words in the question and in the answers:

all, always, never, only: check that the answer is true every time, not most of the time.
except, not: you are looking for the one wrong choice. Read each answer as if it starts with "This is true:" and pick the one that is false.
first, most: more than one answer may be true. Pick the one that comes first or matters most.

When a word in an answer is new to you, do not skip it. Write it in your list. Skipping words is how right-looking but incomplete answers get picked.

Do your passing math before you book

The federal rule says a driver applicant must correctly answer at least 80 percent of the questions on each knowledge test. Your state's manual tells you how many questions your test has, so do the math with your own number. Our guide on how many questions are on the CDL test is a good place to start looking.

Two formulas:

Wrong answers you can afford = total questions x 0.20, rounded down.
Right answers you need = total questions x 0.80, rounded up.

Example: say your test has 50 questions. 50 x 0.20 = 10, so you can miss 10 and need 40 right. Say another test has 30 questions. 30 x 0.20 = 6, so you can miss 6 and need 24 right. These counts are examples only. Use the number from your state.

Copy this note into your phone and fill in the blanks:

My passing math (example note) My test: General Knowledge. Questions on my test (from my state manual): ___. Wrong answers I can afford: ___ x 0.20 = ___. Right answers I need: ___ x 0.80 = ___. After each practice test: Score ___ percent. W misses ___. K misses ___.

To check a practice score, divide right answers by total questions and multiply by 100. Getting 8 right on a 10-question test is 80 percent.

Book when your last two tests are above 80 and your W count is going down

Do not judge yourself on one test. Ten questions is a small sample, and one lucky or unlucky day can fool you. Look at several tests across several days.

If this is true	Do this
Practice scores are below 80 percent	Fix your W and K misses, then test again in a few days.
Scores sit right at 80 percent	One tired day could put you under. Do one more review round before you book.
Scores are above 80 for two tests in a row, and W misses are dropping	Check your state's rules, then book.
You do not know your state's question count	Look it up first. Do not guess.

Here is a ready-to-book note you can say to yourself: "My last two practice tests were at or above 80 percent, my W count is going down, and I re-drilled every K miss. Now I check my state's rules and book."

The 9-point readiness checklist works well next to this note. If you want to check whether your practice source is any good, read how to check a CDL practice test.

Four mistakes that cost you the most

Memorizing answer letters. The order changes. You can miss the same idea when the words are different.
Skipping words you do not know. You may pick an answer that looks right but is incomplete.
Treating 80 percent as a safe target. A score right on the line leaves no room for a tired day or a misread word. Aim for a margin above it.
Reading the whole manual in one sitting. Use short blocks and review your misses.

Which language your test is offered in depends on your state. Ask your state licensing office or read your state's CDL manual before you book. Do not rely on an app or a forum for that answer.

Do this in the next ten minutes

Open your state's CDL manual and find the number of questions on your test.
Write your passing math note with that number.
Start your word list with 10 words from the General Knowledge section.
