科目一 · Subject 1 · China
The real exam is set in Chinese: 100 questions, 45 minutes, 90% to pass. Kemu One gives you the whole question bank in English and explains the rule behind every answer — so you walk into the 车管所 knowing the material, not just translating it in your head.
Free tier: first 10 questions of every topic + one timed mock exam. No account. Nothing to install.
What does this sign mean?
Explanation. A tunnel mouth drawn on a yellow triangle warns of a tunnel ahead — poor lighting, two-way traffic. Slow down before you enter. GB 5768-2022
What's inside
The test rewards people who understand the rule, not people who memorise 1,955 answer keys. Every screen here is built around that difference.
1,955 multiple-choice and true/false questions covering traffic laws, road signs, vehicle basics, violations and penalties, and accident handling.
Each answer tells you which regulation applies and why the other three options are wrong — including the pairs people confuse most.
A full 100-question mock under the real 45-minute limit, with the same 90% pass mark you need on exam day.
Work through one official category at a time, with per-topic progress so you can see which of the five needs another pass.
Reference guides for sign meanings and the 12 / 9 / 6 / 3 / 1-point violation table — the two areas people fail on most.
Phone, tablet or desktop, light or dark. Your progress stays in the browser and the app opens in one click.
How it works
Most learners are done in one to two weeks of daily practice.
Start with Road Traffic Rules, then signs, vehicle basics, penalties and accident handling. Answer every question, even when you're guessing.
The explanation names the rule — a red fork light closes the lane, a green arrow releases it. Rules repeat across questions; the reasoning transfers.
Take full 45-minute simulations until you score 95% or better several times running, then book the real appointment.
