CDL Prep

doubtful rating

A solid general-knowledge trainer, people really pass CDL on it. But the answer key has recurring errors: questions about stopping distance of empty versus loaded trucks are keyed wrong, and the app marks the correct answer as incorrect. Hazmat coverage is weak, and ads every two questions in practice mode seriously get in the way of studying.

About the rating

The general-knowledge bank is good and many pass, but the answer key has a recurring error: the classic empty truck versus bobtail and loaded-stops-longer items are keyed wrong, and the app marks the correct answer as a mistake. Over half the hazmat exam questions are missing. Ads every 2 questions in practice mode make studying unbearable.

Strengths

What users love

  • Prepares you well for general knowledge
  • Many pass the next day after cramming. The exam mode and question repetition land well
  • And the GK content is called among the best.
Weak spots

What users hate

  • The answer key has recurring errors (stopping distance of empty versus loaded truck and bobtail)
  • And the correct answer is marked wrong. Over half the hazmat exam questions are missing. Ads every 2 questions in practice mode
  • An accidental left swipe wipes all progress
  • And the screen freezes.

Who it is for

People prepping for CDL general knowledge who can tolerate ads or stay in exam mode. For hazmat and disputed braking questions, cross-check with another source.
