Pass China's 科目一 theory test in English

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.

Road traffic conditions & regulations 45:00
Yellow triangular warning sign showing a tunnel entrance

What does this sign mean?

  • A Culvert

  • D Tunnel

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

Everything the exam asks, and the reason behind it

The test rewards people who understand the rule, not people who memorise 1,955 answer keys. Every screen here is built around that difference.

Full question bank

1,955 multiple-choice and true/false questions covering traffic laws, road signs, vehicle basics, violations and penalties, and accident handling.

Answer explanations

Each answer tells you which regulation applies and why the other three options are wrong — including the pairs people confuse most.

Timed mock exams

A full 100-question mock under the real 45-minute limit, with the same 90% pass mark you need on exam day.

Study by topic

Work through one official category at a time, with per-topic progress so you can see which of the five needs another pass.

Signs & demerit sheets

Reference guides for sign meanings and the 12 / 9 / 6 / 3 / 1-point violation table — the two areas people fail on most.

Any device, no install

Phone, tablet or desktop, light or dark. Your progress stays in the browser and the app opens in one click.

How it works

Three passes and you're ready

Most learners are done in one to two weeks of daily practice.

  1. Work through each topic once

    Start with Road Traffic Rules, then signs, vehicle basics, penalties and accident handling. Answer every question, even when you're guessing.

  2. Read the explanation for everything you got wrong

    The explanation names the rule — a red fork light closes the lane, a green arrow releases it. Rules repeat across questions; the reasoning transfers.

  3. Sit timed mocks until you're consistent

    Take full 45-minute simulations until you score 95% or better several times running, then book the real appointment.
