Road Signs, Signals and Road Markings
Road signs in Burundi follow international conventions, so candidates should recognise three families: warning signs (triangular, red border, symbol inside), regulatory signs (circular; red ring for prohibitions such as speed limits, blue for mandatory instructions), and information or direction signs (rectangular, often blue or green). Learn signs by shape and colour as well as by symbol, because exam questions frequently describe a sign rather than show it.
Traffic signals work in a fixed hierarchy: a police officer's signals override traffic lights, and traffic lights override signs and markings. A flashing amber or a flashing red means proceed only with caution after yielding; a green light does not license you to enter a junction you cannot clear. Road markings carry legal weight: a continuous white line must not be crossed, a broken line may be crossed when safe, and zebra stripes give pedestrians priority.
Common traps: confusing a prohibition (red ring) with a mandatory instruction (blue circle); assuming a warning triangle means 'stop'; and treating a green light as an absolute right of way. Another frequent trap is a sign whose meaning changes with a supplementary plate (for example a time or vehicle-type restriction).
Rule of thumb: identify shape first, then colour, then symbol. Worked example: a circular sign with a red border showing '50' means a maximum speed of 50 km/h; a triangular sign with the same number would not exist, because speed limits are always regulatory, never warning.
