The written knowledge test for a CLP primarily assesses the applicant’s understanding of traffic laws, road signs, vehicle operation, and safety regulations that are essential for commercial vehicle operation.
Each type of endorsement (air brake, passenger transport, tanker, etc.) requires a separate written test in addition to the general knowledge test. These tests focus on the specific operations, safety procedures, and regulations related to each endorsement.
Many states offer the written knowledge test for the CLP in various languages to accommodate applicants who are not fluent in English. The specific languages offered may vary by state.
If you plan to drive a vehicle equipped with air brakes, you are required to take and pass the air brake knowledge test. This test covers the operation and safety protocols related to air brake systems, which are common in many commercial vehicles.
The CLP written knowledge test focuses on vehicle operation, safety regulations, and federal laws rather than basic driving skills. Basic driving skills are assessed during the road test once you hold the CLP and are ready for practical training.
