Bit short for the price point.

Definitely not a replacement for reading/studying the handbook but questions tend to be rather relevant. Although, there's a section on road signs that seems rather ridiculous(if you don't know what a red light means, driving commercially probably isn't your best idea).

Would like to see a practice section and an actual test section rather than showing right or wrong as soon as the answer is clicked on.

All in all I think this could be a good buy but it's a bit pricey for what you're getting at the moment.

Not reliable

This app is very useful but isn’t a great source. I actually have the official NYC CDL cheat sheets. The question and answer are not the same. This app wouldn’t be reliable if you were studying for the NYC exams. I wouldn’t say this app is a waste of money but it’s not worth $10. There are free apps available. Good luck.
