What must you provide when applying for a CDL?

When applying for a Commercial Driver's License (CDL), it is essential to provide valid identification, along with a medical exam certificate and proof of residency. Valid identification ensures that the applicant’s identity is verified, which is crucial for any licensing process. The medical exam certificate confirms that the applicant meets the health standards required to operate commercial vehicles safely. Lastly, proof of residency is necessary to establish that the applicant is a resident of the state where they are applying for the CDL. Together, these documents help ensure that only qualified individuals receive a CDL, maintaining safety on the roads.

The other options do not encompass all necessary requirements. While prior driving experience and driving history may be relevant factors in assessing qualifications, they do not cover the basic identity verification and health requirements that are critical for the CDL application process. A criminal background check might be part of the screening process in some jurisdictions, but it is not universally required as part of the initial application for a CDL.
