You should not use your horn:
- When visibility ahead is limited.
- If you might hit another vehicle.
- Near blind pedestrians. ✓
Answer: C. Near blind pedestrians.
You should not use your horn near blind pedestrians. The handbook says plainly not to honk at a blind person.
Why this is the answer
The handbook explains that pedestrians with guide dogs or white canes have the right-of-way at all times and are partially or totally blind. It also notes that blind pedestrians rely on sound to know a vehicle is nearby, which matters especially with quiet hybrid or electric cars. Honking would interfere with that, so the handbook tells drivers not to honk at a blind person.
Why the other answers are wrong
- A. When visibility ahead is limited. — Nothing in the passages says to hold back the horn when you cannot see far ahead; the passages say nothing about using the horn in low-visibility conditions.
- B. If you might hit another vehicle. — The passages do not discuss the horn in connection with a possible collision; a horn is not described there as something to avoid in that situation.
Remember it
A blind pedestrian is listening for your car, so your horn is noise that confuses rather than helps.
