What makes it different

Every wrong answer is explained on its own terms

Not one generic explanation, but why the option you picked is wrong. Then the correct answer, then each remaining option with its own separate reason — and the handbook passage the rule comes from. Here is a real question, taken apart.

Which lane is known as the Number 1 Lane?

The far left lane
The far right lane
CThe centre lane
DThe HOV lane, whichever side it is on

1
The answer you picked
BThe far right lane
2
Why that answer is wrong
Why this is wrong
Numbering starts from the left, so the far right lane has the highest number
3
What was actually right
AThe far left lane
4
The rule behind it
The left, or fast, lane is called the Number 1 Lane. The lane to its right is the Number 2 Lane, followed by the Number 3 Lane, and so on.
5
The other options, each on its own terms
- CThe centre lane's number depends on how many lanes there are
- DThe numbering is positional and does not depend on lane type

Where it comes from
Handbook · Choosing a Lane

This is not a sample. All 500 questions are built this way, and every one of them names the handbook passage it comes from.

The handbook

Armenian and English, side by side

The DMV publishes the Driver Handbook in Armenian, and the app carries both versions — not a translation of the English, the real thing, with the English beside it when a term matters. Below is an extract from one section.

Signs

Լիովին կանգ առեք՝ նախքան հետիոտնային անցում մտնելը կամ կանգառի գծից առաջ։ Եթե կանգառի գիծ կամ հետիոտնային անցում չկա, կանգ առեք նախքան խաչմերուկ մտնելը։ Շարունակելուց առաջ ստուգեք երթևեկությունը բոլոր ուղղություններով։
Make a full stop before entering the crosswalk or at the limit line. If there is no limit line or crosswalk, stop before entering the intersection. Check traffic in all directions before proceeding.
Դանդաղեցրեք արագությունը և պատրաստ եղեք կանգ առնելու՝ ճանապարհը զիջելու ցանկացած տրանսպորտային միջոցի, հեծանվորդի կամ հետիոտնի, նախքան շարունակելը։
Slow down and be ready to stop to let any vehicle, bicyclist, or pedestrian pass before you proceed.

Topics

What you study

Questions are grouped by topic, and the groups are not the same size. Each card is as large as the part of the bank it holds, so you can see where the weight is before you start — and work on the topic that is actually giving you trouble.
