One of the fastest ways to find out whether you’re actually ready for Cambodia’s driving theory test isn’t reading a list of rules - it’s trying to answer questions about them. Working through sample driving test questions Cambodia learners are likely to face helps you spot gaps in your knowledge, get used to the multiple-choice format, and build the kind of confidence that makes exam day feel routine instead of stressful.

Below are 12 original Cambodia driving test practice questions with answers, grouped by the five categories used throughout this site: Road Signs, Traffic Rules, Speed & Alcohol Limits, License & Documents, and Motorbike Rules. Each question comes with a short explanation so you understand why the correct answer is correct - not just which letter to pick.

A quick note before you start: these are original practice questions written for this guide, not leaked or official exam questions. They’re designed to cover the same kinds of topics you’ll see on the real test, so they’re a useful warm-up - but they’re not a substitute for working through the full question bank in the app.

Road Signs

Road signs are one of the largest topics on the test, and this short Cambodia road sign quiz questions set is a good way to check whether the shape-and-color system has clicked yet.

1. What does a circular sign with a red border generally mean?

• A. Information for drivers
• B. A prohibition - something you must not do (Correct answer)
• C. A warning about a hazard ahead
• D. A direction to a nearby town

Explanation: In Cambodia’s road sign system, red circular signs are prohibition signs - they tell you something is not allowed, such as “no entry” or “no overtaking.” Recognizing the red circle shape instantly is one of the quickest wins available, because the meaning stays the same no matter what’s pictured inside.

2. A yellow triangular sign with a red border is used to:

• A. Warn drivers of a hazard or change in road conditions ahead (Correct answer)
• B. Show the maximum speed limit
• C. Confirm that a maneuver is mandatory
• D. Mark the entrance to a expressway

Explanation: Yellow (or red-bordered triangular) signs are warning signs - think sharp bends, pedestrian crossings, or uneven roads ahead. They don’t forbid or require anything; they simply tell you to slow down and pay extra attention to what’s coming.

3. A blue circular sign showing an arrow pointing straight ahead means:

• A. You may go straight or turn, at your choice
• B. Straight ahead is forbidden
• C. You must proceed in the direction shown - it’s a mandatory instruction (Correct answer)
• D. The road ahead is for pedestrians only

Explanation: Blue circular signs are mandatory signs - unlike the “must not” red circles, blue circles tell you what you must do, such as following a specific direction, using a particular lane, or maintaining a minimum speed. Mixing up red and blue circles is a common mistake, so it’s worth drilling this distinction specifically.

Traffic Rules

These questions cover the everyday rules of who goes first, how to behave at junctions, and general road conduct.

4. At an intersection with no traffic signs or signals, who generally has the right of way?

• A. Whichever vehicle is larger
• B. The vehicle traveling fastest
• C. Traffic coming from the right, in the absence of other rules (Correct answer)
• D. Whoever arrives at the intersection first, regardless of direction

Explanation: When there’s no sign, signal, or marking to clarify priority, the general default is to give way to traffic approaching from the right. This kind of unmarked-intersection question often trips people up because the “obvious” answer (first to arrive) isn’t always the legally correct one.

5. When you want to change lanes on a multi-lane road, you should:

• A. Change lanes quickly so other drivers don’t have time to react
• B. Signal in advance, check mirrors and blind spots, and move only when it’s safe (Correct answer)
• C. Only signal after you’ve already moved into the new lane
• D. Sound your horn instead of signaling

Explanation: Lane changes should always be signaled in advance and only completed once you’ve confirmed it’s safe by checking mirrors and blind spots. This is both a road-safety basics question and a reminder that signaling is meant to communicate your intention before you act, not after.

6. If you’re approaching a pedestrian crossing and people are waiting to cross, you should:

• A. Speed up slightly to clear the crossing before they step out
• B. Slow down and be prepared to stop to let pedestrians cross safely (Correct answer)
• C. Only stop if a police officer is directing traffic
• D. Sound your horn to warn pedestrians not to cross

Explanation: Pedestrians waiting at a crossing have priority, and drivers are expected to slow down and stop if needed. This kind of question tests whether you understand that traffic rules exist to protect the most vulnerable road users, not just to keep vehicles moving.

Speed & Alcohol Limits

This category covers how fast you’re allowed to go in different settings, and the rules around driving after drinking.

7. Compared to rural or open roads, speed limits in urban or built-up areas are generally:

• A. The same, since speed limits don’t depend on location
• B. Lower, to account for pedestrians, intersections, and heavier traffic (Correct answer)
• C. Higher, to help traffic move through busy areas faster
• D. Not regulated at all

Explanation: Built-up areas have more pedestrians, cyclists, parked vehicles, and intersections, so speed limits are set lower than on open roads to give drivers more time to react. Questions in this category often ask you to compare limits across different road types rather than recall an exact number, so understanding the reasoning helps even if a specific figure slips your mind.

8. What is the safest amount of alcohol to consume before driving?

• A. One small beer is fine for most drivers
• B. It depends on your body weight, so there’s no fixed answer
• C. None - the safest approach is not to drink any alcohol before driving (Correct answer)
• D. Alcohol only affects driving ability after several drinks

Explanation: Even small amounts of alcohol can affect reaction time, judgment, and coordination, and driving under the influence is both illegal and dangerous. While legal limits exist, the safest and simplest rule - and the one theory tests reward - is that the best amount to drink before driving is none at all.

9. If you’re driving a heavily loaded vehicle or towing something, your stopping distance will:

• A. Stay exactly the same as an unloaded vehicle
• B. Increase, so you should leave extra following distance and reduce speed (Correct answer)
• C. Decrease, because the extra weight helps the brakes grip
• D. Only matter on wet roads

Explanation: More weight means more momentum, which means longer stopping distances. This question connects the “speed limits” topic to real-world driving: knowing the limit isn’t enough if you don’t also adjust your speed and following distance for the conditions and load you’re carrying.

License & Documents

This section covers what you’re required to carry and how Cambodia’s licensing system works - often an underrated topic compared to road signs.

10. Which of the following should a driver normally carry while driving?

• A. Only their national ID card
• B. A valid driving license for the vehicle category they’re operating (Correct answer)
• C. Nothing, as long as the vehicle is registered
• D. A copy of the vehicle’s purchase receipt only

Explanation: Drivers are expected to hold and carry a valid license that matches the type of vehicle they’re operating - for example, a motorbike-specific license for riding a motorbike. This is a good reminder that the theory test isn’t only about driving behavior; it also checks that you understand basic legal requirements for being on the road at all.

11. If your driving license has expired, you should:

• A. Continue driving as normal until you’re stopped by police
• B. Renew it before driving again, since driving on an expired license is not permitted (Correct answer)
• C. Only worry about it if you’re involved in an accident
• D. Use your old license plus a printed copy of your ID

Explanation: An expired license is treated as not having a valid license at all, so it needs to be renewed before you drive again. License & Documents questions like this are easy to overlook if you’ve been focused entirely on road signs and traffic rules, but they’re a regular part of the question bank.

Motorbike Rules

Motorbikes make up the majority of vehicles on Cambodian roads, and this Cambodia motorbike theory test sample questions group covers rules that apply specifically to riders - and often to passengers too.

12. When riding a motorbike, who is required to wear a helmet?

• A. Only the rider, not any passengers
• B. Only passengers, since the rider has more control
• C. Both the rider and any passengers (Correct answer)
• D. Helmets are optional for short trips

Explanation: Helmet requirements generally apply to both the rider and passengers, not just the person controlling the motorbike. This is one of the most commonly tested motorbike-specific rules, and it’s also one of the simplest real-world habits to get right every single time you ride.

Keep practicing: mock exams and category drills

Twelve questions are a useful gut-check, but the real question bank is much larger - and the real test mixes questions from all five categories together under a 20-minute timer. Once you’ve worked through the sample questions above, here’s how to keep building:

• Take a full mock exam to see how you handle 25 mixed questions under timed conditions, just like the real test.
• Drill weak categories with category practice - if you found the Speed & Alcohol Limits or License & Documents questions above tougher than the road sign ones, that’s exactly the kind of pattern category practice is designed to fix.
• Review the road sign system with the flashcards if questions 1-3 felt shaky - shapes and colors are some of the easiest points to lock in once they’re familiar.
