Cambodia Category A Motorcycle Test common mistakes
Cambodia Category A Motorcycle Test · Understand the traps and how to avoid them.
Choosing 'stop and wait' at every junction instead of applying the Cambodian right-of-way rule that the vehicle on the right has priority at unmarked intersections, and then guessing at roundabouts and T-junctions.
Candidates carry over the priority rules of their home country or assume the bigger vehicle always goes first, so they answer by instinct rather than by the rule written in the Road Traffic Law.
What to do instead
Learn the specific hierarchy as a list: at an unmarked intersection the vehicle approaching from the right has priority; at a T-junction the through road has priority; at a roundabout traffic already circulating has priority. For each practice question, first name the junction type, then apply the matching rule, and write down the rule you used so you can spot which one you keep confusing.
Treating a helmet as optional for short trips, for pillion passengers, or in hot weather, and answering 'only the driver must wear one' or 'only on national roads'.
Everyday observation in Cambodia shows many riders without helmets, so candidates assume the law is advisory or applies only to the driver, and comfort on hot days is used to justify exceptions.
What to do instead
Memorise that the law requires a helmet for both the rider and any passenger, on all roads and for all trip lengths, and that the helmet must be properly fastened. Build a firm answer pattern: if a question mentions a passenger or a short trip, the helmet requirement does not change. Also learn the enforcement consequence, since penalty questions often test the same point from the other direction.
Reading a warning sign as a prohibition sign, or confusing the meaning of a triangular sign, a circular red-bordered sign and a blue circular sign, and then answering by the picture's shape rather than its meaning.
Candidates learn sign images by memory without learning the shape and colour coding, so under exam pressure they recognise the picture but not the rule it carries.
What to do instead
Study the coding system first: triangles warn, red-bordered circles prohibit, blue circles instruct, rectangles inform. Then practise by describing each sign in words before choosing an answer, for example 'red circle with a white bar means no entry'. This lets you answer even when the sign is unfamiliar, because the shape tells you the category.
Answering road-marking questions as if markings are only decorative, for example treating a solid centre line as crossable, treating a broken line as a no-overtaking zone, or ignoring yellow kerb markings and stop lines.
Markings are faded or partly worn on many Cambodian roads, so riders learn to ignore them and never build a clear rule about solid versus broken lines.
What to do instead
Fix the rule in one sentence: a solid line must not be crossed, a broken line may be crossed when it is safe and legal, and a stop line requires a full stop before proceeding. For each marking question, identify the line type first and then the permitted action. Review the marking section together with overtaking rules so the two reinforce each other.
Braking hard with only the front brake in an emergency, or grabbing the brake mid-corner, instead of applying both brakes progressively before the bend and using the rear brake for low-speed control.
New riders fear the front brake locking and rely on the rear, or they panic and snatch the lever, which is exactly the behaviour that causes a skid or a fall in the test scenario questions.
What to do instead
Practise the sequence until it is automatic: roll off the throttle, apply both brakes together with progressive pressure, more front than rear on dry tarmac, and finish braking before turning in. Slow-speed manoeuvres use the rear brake with light throttle. When answering, ask what the question rewards: stopping distance, stability, or control in a turn, and match the braking method to it.
Treating the following distance as a fixed number of metres regardless of speed, weather or road surface, and choosing the shortest option because it 'keeps traffic moving'.
Candidates memorise a single figure without understanding that stopping distance grows with speed and shrinks grip, so they cannot adapt when a question adds rain, gravel or a loaded motorcycle.
What to do instead
Learn the two-second rule as the baseline and know that it must be doubled in rain or on loose surfaces, and extended at night or when carrying a passenger. Work through stopping-distance questions by adding reaction distance plus braking distance, and note that wet roads and worn tyres increase the braking part. If an option offers a shorter gap because traffic is slow, check whether the question has already told you the surface is wet.
Answering that the rider should first move an injured motorcyclist out of the road, remove their helmet, or give them water, before checking breathing and calling for help.
Candidates act on instinct to 'clear the scene' or to make the casualty comfortable, without knowing that moving a suspected spinal injury or removing a helmet can cause serious harm.
What to do instead
Learn the fixed order: secure the scene and warn other traffic, check responsiveness and breathing, call emergency services, control severe bleeding, and only then consider movement, which should be avoided unless there is immediate danger such as fire. Learn that a helmet is removed only by trained rescuers or when the airway is blocked. Answer first-aid questions by choosing the step that comes first in this order, not the one that looks most helpful.
Leaving the scene of a collision because the damage was minor, or agreeing to a private cash settlement without exchanging details, and answering that a rider may ride away if no one was hurt.
Riders believe a small scrape does not count as an accident, or they fear penalties and official involvement, so they do not learn the legal duty that applies regardless of damage size.
What to do instead
Memorise the duties that apply after any collision involving injury or property damage: stop, make the scene safe, give assistance to the injured, exchange names, addresses, plate numbers and insurance details, and report to the police. Learn that failing to stop and assist is a separate and more serious offence than the collision itself. For scenario questions, pick the option that includes stopping and reporting, not the one that resolves things privately.
Riding without a valid licence for the motorcycle's engine size, without registration documents carried, or without compulsory insurance, and answering that a licence for a small motorcycle covers any motorcycle.
Candidates treat licence categories and paperwork as bureaucracy unrelated to riding skill, and they assume one motorcycle licence covers all capacities.
What to do instead
Learn the licence categories and the engine-capacity thresholds that separate them, plus what must be carried: licence, registration and compulsory insurance. Build a checklist answer for any documents question: valid licence matching the vehicle, registration, insurance, and identity documents. When a question changes the engine capacity or the rider's age, re-check the category instead of assuming the same licence applies.
Guessing penalty amounts and points by picking the middle or largest number, rather than knowing which penalties are fixed fines, which involve licence suspension, and which lead to court.
Penalty figures are easy to confuse and candidates never group them, so they rely on the size of the number and on the assumption that the harshest option is the correct one.
What to do instead
Group penalties by type instead of memorising isolated numbers: helmet and licence offences, speeding and red-light offences, drink-riding, and offences that lead to suspension or court. Learn the threshold for drink-riding and the fact that refusal to be tested carries its own penalty. For numeric questions, eliminate options that belong to a different offence category before comparing amounts, and flag any figure you cannot confirm rather than guessing.
