Which checklist do the lessons follow?

The 2022 AAMVA vehicle inspection test, in checklist order: 32 items for Class A and 26 for Class B, which has no coupling or trailer items. The app knows which test version your state runs and whether your truck has air or hydraulic brakes, and shows a notice in the states still on the older test.

What is free and what is in Pro?

With a free account you get two full lessons of your choice. Pro unlocks every lesson, the timed mock inspection with the AI examiner, and offline lesson downloads.

Can I practice in Spanish?

You can read every script with a Spanish explanation, and the app itself runs in English or Spanish. You practice saying the script in English, because the skills test is taken in English.

CDL skills test, part one

Pass the pre-trip with Mr. Egg

The vehicle inspection is where most people fail the skills test. Mr. Egg walks you around the truck one checklist item at a time and tells you exactly what the examiner wants to hear.

How a lesson works

Every lesson runs the same three steps, so the walk-around becomes habit.

1
Where to stand
A map of the rig shows where you walk to, so you inspect in the same order as the examiner’s checklist.
2
What to look at
Mr. Egg walks up, points, and the camera moves in on the part.
3
What to say
Each line of the script lights up the part it names, in the words the examiner listens for.

The examiner script in English with the Spanish explanation underneath

Explained in Spanish, practiced in English

Every script has a Spanish explanation underneath, so you know what each line means. The skills test is taken in English, so the words you practice are the ones you will say.

Mock inspection results quoting the words that earned each point

A mock inspection with an AI examiner

Run a quick five-item mock or the full walk-around against the clock, answer out loud, and take one hint per item if you need it. Each item is scored as you go, and the result quotes which of your own words earned each point and what to add next time. Mock inspections are part of Pro.

Every item on the checklist

32 lessons in checklist order, from the air brake check in the cab to the lights on the back of the trailer. Class B drivers get the 26 that apply to a straight truck. After each lesson you say the script back and compare it line by line.

Start with the air brakes. Miss a step and you're done.

The full pre-trip inspection checklist, with the script for the air brake check

Pre-trip questions

It is the first part of the CDL skills test. You walk the vehicle and, for each item on the checklist, name it, point to it and say what you are checking it for. You only get credit for what you say out loud, and a mistake on the air brake check fails the whole inspection.
