This sign means?

This sign means?
  1. Railway crossing ahead, prepare to stop when lights are flashing
  2. School bus stop ahead
  3. Signal lights ahead, prepare to stop when lights are flashing ✓
  4. No traffic light ahead

Answer: C. Signal lights ahead, prepare to stop when lights are flashing

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

Why this is the answer

The handbook lists this among warning signs, which warn of possible hazards ahead. It specifically gives the meaning as signal lights ahead, with the instruction to prepare to stop when the lights are flashing. That fits the bank answer: the sign is not about a railway crossing or a bus stop; it warns that you are approaching traffic signals and may need to stop.

Why the other answers are wrong

Remember it

When this warning appears, think signals first and get ready to stop if they are flashing.
