Idaho CDL Resources

Here are more resources related to getting your CDL in Idaho:

CDL Permit Test in Idaho

Before getting your CDL, you must obtain your Commercial Learner's Permit. The process for obtaining this permit is simple, and this is a complete outline for what you need to know to be on your way to get your CDL.

Your Idaho Commercial Learner's Permit will be valid for 180 days. During those 180 days, you will be able to practice driving a commercial truck on public roads only and with a licensed commercial driver. The federal law states that you must have your CLP for at least 14 days before you test for your CDL.

Before you begin this process, it is very important that you read and study the Idaho CDL Manual because it contains all of the information you will need to successfully pass the permit and license exams.

You can take the actual permit test as many times as necessary, but keep in mind that you will need to pay the permit fee every time. Additionally, by the time that you retake the permit test it is possible that your medical examination might need to be updated.. Therefore, prepare for success the first time with all of the tools at your disposal.

While it is not required by Idaho or the Federal Motor Carrier Safety Administration, it is recommended that you take a CDL education class before beginning this process. This class serves a similar process to the driver's education courses available to teenagers before they get their driver's license.

Testing Fees

Much like getting your CDL, there are a list of fees that you must pay before getting your CLP. Here is a complete list of the fees you will need to pay during the permit process.

  • Commercial Learner's Permit: $29
  • Written tests: $12 (each)*

    *It does depend on what endorsements you are testing for. The price could vary, so expect to pay an average of $12 for your written tests. However, it could be more or less.

  • Skills test: MAX. $200

Testing Locations and Hours

All Idaho CLPs are obtained at your local DMV. You can check to see where your local DMV is by entering your zip code on the DMV website. Once you know your DMV, you can go directly to the location or schedule an appointment online to take your permit test.

Permit Knowledge Test

To obtain your CLP, you must pass the written knowledge test. The test has 50 multiple-choice questions, and to pass you must answer 40 correctly. This means you must score 80% or higher in order to obtain your CLP.

The knowledge test covers a variety of topics such as understanding the pre-trip inspection and knowing how to drive on black ice. This test is similar to the general knowledge test that you took when you first obtained your civilian driver's license. Because of this portion of the CDL process, it is very important that you read the Idaho CDL manual (linked above) so you can pass the knowledge test.

There are several free CLP Practice Tests available online where you can see questions similar to the ones that you will see on the exam. You can take these tests multiple times, and often they will explain if or why your answer was incorrect. This will help you as you prepare to take the actual test.

You will need to take similar knowledge tests for additional endorsements or skills that you want to use when you are a licensed driver. For example, if you want to be qualified to drive hazardous materials, you must pass the HAZMAT knowledge test before receiving this endorsement. Knowledge tests for endorsements are also found on these practice sites.

Requirements for Taking the Test

The requirements for getting your CLP are the same as the requirements you must meet to get your CDL. It is possible that these will have additional fees, but because the vary from person to person, they are not listed above. Before you get your CLP you must meet the following requirements:

  • Be at least 18 years old (must be 21 to obtain certain endorsements or drive out of the state)
  • Have a civilian Idaho Driver's License
  • Prove that you are a resident of Idaho
  • Have a U.S. Social Security Card
  • Self-certify that you are physically fit to drive, which you can do in person at the DMV or with this online portal

    The Idaho government has also put together this chart that you can use to understand the self-certification process more.

  • Obtain a Medical Examiner's Certificate

    This is a certified statement from a doctor approved by the Federal Motor Carrier Safety Administration that says you are fit to drive. Visit the FMCSA website for more information about where you can find a doctor.
