Cambodian Traffic Law and the Road Traffic Law
The legal framework
This domain tests whether you know the Road Traffic Law as the base rule set for every rider, not just car drivers. Cambodian traffic keeps to the right. A motorcycle is a vehicle, so the same core duties apply: hold the correct licence class, carry the required documents, wear a helmet, have compulsory insurance, and obey signals, signs, markings and police directions.
Hierarchy of rules
When instructions conflict, apply this order: police officer’s signal, then traffic light, then road sign, then road marking, then the general rule. A police officer may lawfully direct you through a red light or hold you at a green one. The law also creates duties after a crash: stop, give assistance, exchange details, and report when required.
Core rider obligations
- Ride on the right and use the correct lane; do not ride against traffic.
- Obey the default and posted speed limits; a lower sign always controls.
- Do not ride under the influence of alcohol or drugs; the ordinary BAC limit is 0.05%.
- Both rider and passenger must wear a fastened helmet.
- Carry a valid licence for the machine, vehicle registration, and compulsory insurance.
Worked example
You approach a red light. An officer waves you forward. Reasoning: the officer’s signal outranks the light, so proceeding is lawful if it is safe. If you instead treat the red light as absolute and refuse, you are failing to obey a police direction. If the officer is not directing traffic, the red light controls.
Traps that cost marks
Assuming signs outrank police; thinking the law applies only to cars; forgetting the passenger helmet; and treating a green light as an automatic right to go - green means proceed only if the way is clear.
Exam focus
Expect scenario questions on right-hand traffic, rule priority, alcohol, helmet scope, and post-crash duties rather than abstract definitions.
