Road Signs
The Road Signs domain tests whether you can read Nigeria's sign system instantly and act on it correctly. A sign you have to decode at speed is a sign you have already missed. Questions arrive as sign-to-meaning matching, 'what must you do when you see this sign', and picture-based hazard decisions.
Shape and colour tell you the sign's job
- Red-bordered triangle: warning of a hazard ahead.
- Red ring (circle): prohibition - no entry, no parking, speed limit, no overtaking.
- Blue circle: mandatory instruction - keep left or right, minimum speed, route reserved for a vehicle class.
- Rectangle or square: information or direction - hospital, one-way street, parking, motorway.
- Octagon: STOP. Inverted triangle: GIVE WAY. Both use unique shapes so they are identifiable from the rear and in poor light.
- A supplementary plate under a sign narrows its meaning: times, distance, 'for 300 m', or the vehicle class affected.
Signs the exam returns to
Warning: schoolchildren, pedestrian crossing, slippery road, bend, crossroads, road narrows, narrow bridge, level crossing with and without barriers, cattle, falling rocks. Regulatory: no entry (red disc with white bar), no stopping, no parking, no U-turn, no overtaking, weight and height limits, and the 30/50/80/100 speed limits.
Worked example
A driver approaching a junction sees an inverted triangle marked GIVE WAY, then 60 m later a red-ringed 50. Reasoning: the triangle means he has no automatic right of way - he must slow, look and yield to traffic on the major road, stopping if necessary. The 50 forbids exceeding 50 km/h from the sign onward, and it continues past the junction until another limit sign cancels it. After turning he must not accelerate back to the old limit.
Traps that cost marks
Confusing no entry (red disc, white bar) with no stopping or no parking. Reading a warning triangle as an order to stop. Assuming a speed limit ends at the next junction. Ignoring the supplementary plate and applying a lorry restriction to a car.
