This sign means?

- Traffic lights ahead. Slow down ✓
- Bump 120 meters ahead
- School bus stop ahead
- Stop 150 meters ahead
Answer: A. Traffic lights ahead. Slow down
It means traffic lights are ahead and you should slow down.
Why this is the answer
The handbook lists this among the common warning signs and gives its meaning as traffic lights ahead, with the instruction to slow down. In other words, the sign tells you that a signal-controlled location is coming, so you should reduce speed and be ready for the traffic lights. The passages do not tie this warning to a specific distance, a bump, a school bus stop or a stop line. The answer follows directly from the wording in the warning-sign list.
Why the other answers are wrong
- B. Bump 120 meters ahead — The handbook describes a bump or uneven pavement sign as a warning to slow down and keep control, not as a sign stating a distance of 120 metres, and no such distance appears in the passages.
- C. School bus stop ahead — The passages describe a school zone warning sign about children and a school zone, not a sign for a school bus stop.
- D. Stop 150 meters ahead — The passages mention a stop sign ahead warning, but they do not give a 150-metre distance, and the correct sign here is about traffic lights, not a stop.
Remember it
Link the signal warning to the action: lights ahead means slow down.
