Essential Khmer Driving and Traffic Vocabulary (With English Translations)

By Testdrive KH team · June 21, 2026

If you’re preparing for Cambodia’s driving theory test, there’s a good chance you’ll run into Khmer somewhere along the way - whether that’s the test itself, a sign at the licensing office, or instructions from traffic police. Even if you’re testing in English, a basic vocabulary of Khmer driving and traffic terms makes the whole process less stressful, and it’s genuinely useful for everyday driving in Cambodia afterward.

This post is a practical glossary, not a grammar lesson. It’s organized into a few simple reference tables you can scan before your test or come back to whenever a word looks unfamiliar.

A quick note on pronunciation: the romanization used here is a simple, approximate guide for English speakers - not a formal linguistic transliteration. Khmer pronunciation has sounds that don’t map perfectly onto English letters, so think of these as “close enough to be understood,” not exact spelling rules.

Why vocabulary matters for the theory test

If you’re taking the Cambodia driving theory test in Khmer, the obvious reason to learn this vocabulary is that you need to understand the questions. But even if you’re testing in English, there are a few situations where knowing key Khmer terms in Khmer helps:

• Switching between languages while studying. A lot of learners practice mostly in one language but want to double-check their understanding in the other - especially for traffic-law terms where precise wording matters.
• Real-world signage and paperwork. Road signs, license application forms, and notices at testing centers are often in Khmer (sometimes with English alongside, sometimes not).
• Talking to traffic police or office staff. Even a few recognizable words - “license,” “helmet,” “speed” - can make an interaction much smoother, especially if your Khmer is otherwise limited.
• Recognizing terms even if you can’t read every sign. Knowing that ច is the start of “ចរាចរណ៍” (traffic) helps you spot traffic-related signage even before you can read the whole word.

The good news is that the vocabulary itself is fairly compact. A few dozen words and phrases cover almost everything you’ll encounter on the test and on the road.

Basic road and traffic vocabulary

Here’s a core set of terms that come up constantly - on signs, in test questions, and in everyday conversation about driving. These are useful traffic terms in Khmer and English to know before you go any further.

This isn’t an exhaustive dictionary - it’s the set of words that show up most often when you’re talking about roads, vehicles, and rules. If you only memorize one table from this post, this is the one to focus on.

Road sign category vocabulary

The theory test groups road signs into a few broad categories, and each category has its own Khmer name. Knowing these category names helps you recognize what kind of instruction a sign is giving, even before you work out the exact meaning.

These category names are about recognizing the type of sign you’re looking at - they won’t tell you exactly what an individual sign means. For that, shapes and colors are still your fastest guide. If you want a refresher on how the shape-and-color system works (and which colors map to which categories), see our guide to understanding Cambodian road signs explained.

Useful phrases for traffic police and the licensing office

You’re unlikely to need a long conversation in Khmer, but a handful of short, polite phrases can go a long way - whether you’re stopped at a checkpoint or filling out paperwork at a licensing office. These are framed as simple, respectful phrases rather than full sentences, since tone and context matter more than grammar here.

A practical tip: even if you can’t form a full sentence, saying the word for “license” or “fine” while pointing at the relevant document or sign is often enough to be understood. Staying calm, polite, and patient matters more than perfect pronunciation.

How to practice with both languages using the app

The easiest way to turn this glossary into something that actually sticks is to see these words in context, repeatedly, alongside their English equivalents. Cambodia Test Drive makes that straightforward:

1. Switch the app to Khmer. Use the language toggle in the header to display the entire app - questions, answers, and explanations - in Khmer (ភាសាខ្មែរ).
2. Practice a category you already know well in English. Try the category practice mode, starting with Road Signs or Traffic Rules. Because you already understand the rules, you can focus on matching the Khmer wording to concepts you recognize.
3. Use the road sign flashcards. The flashcards pair each sign with its meaning, which is a quick way to connect a sign’s Khmer name (prohibition, warning, mandatory, information) with what it actually looks like.
4. Try a full mock exam in Khmer. Once individual terms feel familiar, take a mock exam in Khmer to see how they come together in full questions under timed conditions.

Final thoughts

You don’t need to be fluent in Khmer to pass the theory test or drive confidently in Cambodia - but knowing this core set of Khmer driving vocabulary removes a lot of unnecessary friction, whether that’s reading a sign, filling out a form, or having a short, polite exchange with traffic police. Bookmark this glossary, switch the app to Khmer for a session or two, and these terms will start to feel familiar faster than you might expect.
