However, it's important to note that the skills test and the pre-trip inspection test must be taken in English. This is because the CDL skills test requires clear communication between the examiner and the driver, and the pre-trip inspection test involves identifying and describing various components of a commercial vehicle using standard English terminology.
If you choose to take the CDL written test in a language other than English, you will need to bring a qualified interpreter with you to the testing site. The interpreter must be fluent in both English and your chosen language, and they must not have any interest in the outcome of your test. The interpreter will translate the questions for you and your answers for the examiner.
It is important to note that passing a written test in a language other than English does not exempt you from meeting all other CDL requirements, including passing the skills test and meeting all medical requirements.
To request accommodations, you will need to submit a request form and documentation of your disability to ODOT. The request form is available on the ODOT website and must be submitted at least 30 days before your scheduled test date.
Examples of accommodations that may be provided include:
- Extended testing time
- Use of a reader or sign language interpreter
- Use of a computer or other assistive technology
- Large-print or Braille test materials
ODOT will review your request and documentation and determine what accommodations are reasonable and appropriate based on your individual needs.
It's important to note that the accommodation process can take some time, so it's recommended that you submit your request as early as possible. If you have any questions or concerns about the accommodation process, you can contact ODOT for assistance.
If you fail the written test, you will be required to wait at least one day before retaking the test. If you fail the test again, you will need to wait at least seven days before taking it again. After the third failed attempt, you will need to wait at least 30 days before retaking the test.
It's important to note that each time you retake the written test, you will need to pay the testing fee again. The fee for the Class A CDL written test in Oregon is currently $75.
Before retaking the test, it's recommended that you review the study materials and identify areas where you may need additional preparation. You may also want to consider taking a commercial driver's license course or practice tests to improve your knowledge and skills.
Remember that passing the written test is just one step in obtaining a Class A CDL in Oregon. You will also need to pass a skills test and meet all other requirements for obtaining a CDL.
