Review summary

CDL Prep is widely praised for helping users pass CDL written tests and for questions that align with real exams, plus strong endorsement coverage and free access. The main downsides are intrusive ads and occasional content issues (inaccuracies and outdated state content) with gaps in some endorsements. Overall, it's an effective, value-focused study tool for many, but users notice room for content updates and ad relief.

Pros

Helps users pass CDL tests, with many reporting first-time pass results.
Practice questions closely mirror real exams, including General Knowledge, Air Brakes, and other areas.
Covers multiple endorsements (hazmat, tanker, doubles/triples, passenger) aiding in earning endorsements.
Free, ad-supported access provides good value and reduces need for paid alternatives.

Cons

Ads are intrusive and can disrupt practice sessions; multiple reviews mention the need to remove or block ads.
Occasional content inaccuracies and outdated material, including hazmat question errors and state-specific updates (Florida GK, New York endorsements).
Gaps in state-specific coverage and endorsement content that some users want updated or expanded.
