This sign means?

This sign means?
  1. Stop 150 meters ahead
  2. School bus stop ahead
  3. Signal lights ahead ✓
  4. Bump 120 meters ahead

Answer: C. Signal lights ahead

The sign means signal lights ahead, so prepare to stop when the lights are flashing.

Why this is the answer

The handbook's warning-sign list includes the meaning signal lights ahead and adds that you should get ready to stop when the lights are flashing. That points to signal lights ahead: the sign warns that traffic signals are coming up, not a stop, school bus, or bump warning. The passage does not give any distance for this sign.

Why the other answers are wrong

Remember it

Link this sign in your mind with the flashing lights it warns about, so you start preparing to stop early.
