You must yield to a pedestrian using a white cane or guide dog:
- Only when the guide dog is leading the person across the street.
- At all times. ✓
- Only if a crossing guard is present.
Answer: B. At all times.
You must yield to a pedestrian using a white cane or guide dog at all times, so the correct choice is the one saying at all times.
Why this is the answer
The handbook states that pedestrians who use guide dogs or white canes have the right-of-way at all times. Because these pedestrians may be partially or totally blind, the rule is not limited to moments when the dog is visibly leading them or when another person is directing traffic. The passage also tells drivers to be careful when turning or backing up and not to stop in the middle of a crosswalk, since that can push a blind pedestrian into traffic. That supports yielding whenever such a pedestrian is using a cane or guide dog.
Why the other answers are wrong
- A. Only when the guide dog is leading the person across the street. — The right-of-way applies at all times; it does not depend on the guide dog being in the act of leading the person across the street.
- C. Only if a crossing guard is present. — A crossing guard is not mentioned as a condition; the handbook gives these pedestrians the right-of-way regardless of whether a guard is present.
Remember it
White cane or guide dog: yield every time, not only when the person looks ready to cross.
