Many jobs require you to have a commercial driver's license (CDL), such as school bus drivers or equipment operators. If you want to pursue these careers, it’s important to know how to study for a CDL test so you can pass the exam. Understanding various study methods can help you earn a passing score on the test so you can meet certain job requirements.
In this article, we explain what a CDL test is, describe how to study for a CDL test and list jobs that require you to have a CDL to help you explore your career options.
What is a CDL test?
A CDL test is an exam you take to earn your commercial driver’s license. This license allows you to operate large commercial vehicles and buses on public roadways. Most states require you to pass a written exam and a driving test to earn your CDL. There are different types of commercial driver’s licenses, which may require additional exams. For example, if you plan to transport hazardous materials, you may be required to take a specific exam for this endorsement.
How to study for a CDL test
As with any test, it's important to implement various study strategies to prepare effectively for a CDL exam. Use these tips to study for a CDL test:
1. Plan ahead
Set a day to take your CDL test and start studying in advance so you're fully prepared on the day of the exam. Some states require you to take a training course to help you prepare. If your state doesn't, you can still sign up for an online or in-person course to help you learn the material. Research different programs that offer this training course and select the one that works best for you. Beginning your CDL studies early can help you feel more confident about getting a passing score.
2. Know what to study
Before you study, determine the exact material you're expected to know for the CDL test. Review the Department of Motor Vehicles (DMV) CDL study guide for your state. The study guide separates the test into different sections based on the CDL manual. Take notes on key concepts in the guide to help you study. Some of the general elements covered in the CDL DMV handbooks include:
Transporting cargo and passengers
Transporting hazardous and flammable content
On-road driving exam
Applying for a CDL
Based on the CDL you're pursuing, you may also want to study specific topics, such as hazardous materials or school bus driving. Focus on your weak areas to help improve your confidence in those subjects.
3. Take a diagnostic test
Consider taking a diagnostic test to determine the information you already know. A diagnostic test can help you identify areas where you can improve to help you focus your study time more efficiently. Some websites let you take a free general knowledge practice exam for your state. Taking a diagnostic exam also provides insight into what to expect on the day of the CDL exam.
4. Gather your CDL study materials
Compile all the notes from your reading and graded practice tests for every study session. These materials may include your CDL manual, a study sheet and a CDL test prep book. Having all of your study materials together makes for a more efficient study session with plenty of resources and materials for you to use.
5. Use flashcards
Use flashcards to test your knowledge on specific subjects. You can make your own flashcards or find a website or app to download them. Consider making flashcards for subject areas where you want to improve your knowledge. If you make your own flashcards, you can test yourself on the material or have a friend or family member ask you the questions on the flashcards. The more time you spend practicing with your flashcards, the more prepared you may feel for your CDL exam.

6. Consult with others
Sharing knowledge and ideas with other students can help improve your skills and expertise. Join different study groups or forums with other prospective test takers, whether online or in person. Consulting with others can help you brainstorm and provide ideas on how best to answer specific types of CDL questions.
You can also consult with other people who've taken the test. Consider asking them what to expect and what study methods worked for them. Their firsthand experience provides additional insight that can help you prepare for your own test day. If you don't know anyone to ask, solicit advice from other commercial drivers through online forums and message boards.
