I gave 5 stars just so my review would be at the top. If you plan on passing the hazmat test don’t download this app. I studied this app until I could answer all 110 questions right and then I went and took the test and most of the questions on the app weren’t even on the test. Just don’t waste your time on this app and go study something else.

Hi, our app is best used as a supplement to other study resources. It’s designed to reinforce key concepts and provide practice, but pairing it with other materials—like official study guides and additional resources—can give a more well-rounded preparation for the exam.
Great App but

They do need to clean up langue a bit. For example when given the choice of Both A & B it would be nice o actually have the choices lettered. My state Illinois is not compliant with shipping paper order. It would be nice if he test questions actually followed what Illinois uses. Not a big deal just annoying.I like the format and the way the practice questions are broken down into manageable info with CDL book references provided when you get a question wrongTaking test tomorrow 🤞🏾

I have been using this app for only a few days & I can already tell that this is going to be my tool from now on to stay ready.If you stay reedy, you don’t have to get ready.Use this app anytime you have downtime as a tool to keep perishable knowledge from perishing.The issue I always have had with apps in the past was my belief that knowing something isn’t enough. I want to know this material like Billy Graham knew the Bible. That way I can not only quote facts, I can reference where they are in the book.Great tool! I highly recommend it.
I passed!

Went to the dmv today and passed! Studied the heck outta this app, the questions at dmv are not exactly worded the same as on the app, but definitely led me to the right answers . I got 4 wrong that asked about what the hazmat agencies purpose and duty was when notifying them of an emergency. But thanks! Great app

Thank you for your feedback.
New in this version:
• A brand new app icon.
• ERG Lookup now sits in Quick Reference, right beside ERG Basics — the fastest route to a guide number. It's still on the Field Tools screen too, so the path you already know keeps working.
• Clearer naming: the reference category is now "ERG Basics" and the searchable guidebook is "ERG Lookup", each with its own icon so they're easy to tell apart.
• Spanish wording refreshed across the ERG screens and in-app help.
