About this exam

The Cambodia Category B licence is the ordinary car licence issued by the Ministry of Public Works and Transport (MPWT) through its General Department of Land Transport. It authorises you to drive a private passenger car or light vehicle on Cambodian roads, and it is the credential most learners pursue first before later adding categories for heavier vehicles. The assessment has two parts: a theory test of multiple-choice questions on Cambodian traffic law, road signs and markings, safe and defensive driving, vehicle control, right-of-way, driver fitness, emergency response, basic maintenance and licensing rules; and a practical driving test in which an examiner observes your control of the vehicle in real traffic conditions. Preparation works best in layers. Learn the sign and marking vocabulary until recognition is instant, then study the legal rules that decide who goes first, then practise the physical skills - clutch control, smooth braking, mirror checks, signalling - until they are automatic. Reading the official MPWT materials and driving supervised on Cambodian roads, including roundabouts and busy urban junctions, closes the gap between knowing and doing.

What you'll study

Common questions

About Cambodia Category B Driving Test preparation

What does the Category B licence actually let me drive?

It covers private cars and light vehicles for personal use. If you later want to drive lorries, buses or larger passenger vehicles, you need a different category and usually additional experience requirements. Confirm the exact vehicle definitions with the MPWT, since categories and thresholds are set by regulation.

What is the theory test format?

It is a multiple-choice test delivered in Khmer, covering traffic law, signs and markings, safe driving, vehicle handling, right-of-way, driver fitness, emergencies, maintenance and documentation. The current number of questions and the time allowed are published by the MPWT, so check its official site before your test date.

How hard is the exam overall?

Most candidates find the theory test manageable if they study systematically, but the practical test is where people lose points. Examiners watch for smooth control, correct observation and confidence rather than speed. Candidates who have only practised in quiet areas often struggle with busy junctions and roundabouts.

What happens if I fail - can I retake it?

Retakes are permitted, but the waiting period, any additional fee and the number of attempts allowed are set by the MPWT and can change. Ask at the licensing office or check the Ministry's official information for the current rules rather than relying on what other learners tell you.

How long is my licence valid?

Cambodian licences are issued for a fixed validity period and must be renewed before expiry; driving on an expired licence is an offence. The current validity period and renewal requirements are published by the MPWT, so confirm them when you collect your licence so you know your renewal date.

In what order should I study the theory material?

Start with signs, signals and road markings, because they appear inside almost every other question. Then learn right-of-way and intersection rules, which are the most commonly missed. After that, work through safe driving, vehicle control, driver fitness and emergency response, and finish with documentation and penalties.

What are the most common reasons candidates fail?

Typical failures are rolling through a stop line, missing a mirror or shoulder check before changing direction, poor clutch and brake control when starting on a slope, and hesitation at roundabouts or uncontrolled junctions. Failing to give way correctly and ignoring pedestrians at crossings also cost marks.

Do I need to bring my own car to the practical test?

Requirements vary by testing centre, and some centres provide a vehicle while others expect you to bring a roadworthy one with valid documents. Confirm this with the office where you book, and if you bring your own car, check that its brakes, lights, tyres and horn all work before the day.

Is the test available in English?

The theory test is normally administered in Khmer, and the practical instructions are given verbally by the examiner. If your Khmer is limited, arrange to study the terminology in Khmer anyway, because sign names and legal terms are tested in that language. Ask the licensing office about any language provision.

How should I prepare for the practical driving test?

Get supervised practice on the kinds of roads you will be tested on - busy urban streets, roundabouts and narrow side roads - and rehearse starting on a slope, parallel parking and smooth gear changes. Practise narrating your observations aloud so mirror and shoulder checks become habitual before the examiner is watching.
