Step-by-step explanation:
Commercial Driver's License (CDL) tests are used to assess the knowledge and skills of individuals who want to become commercial truck drivers or bus drivers. These tests consist of both written and road tests.
The written test evaluates the knowledge of various topics related to commercial driving, such as traffic laws, vehicle inspection, and safe driving practices. It may require multiple-choice, true/false, or fill-in-the-blank answers.
The road test assesses the driving skills of the applicant, including maneuvers like backing up, turning, and parking. The examiner evaluates the applicant's ability to handle the vehicle safely and efficiently.
