At night, it is hardest to see:

  1. Road signs.
  2. Pedestrians. ✓
  3. Other motorists.
  4. Street lights.

Answer: B. Pedestrians.

At night, pedestrians are the hardest to see.

Why this is the answer

The handbook's pedestrian section tells people walking at night to wear white or light clothing and/or carry a light or reflector. That advice points to the visibility problem: a person on foot is hard for a driver to pick out in the dark. The passages do not make the same night-visibility point about road signs, other motorists, or street lights. The right-of-way chapter also tells drivers to stay on the lookout for pedestrians whether or not they have the right-of-way, reinforcing that drivers must watch for people on foot.

Why the other answers are wrong

Remember it

Picture a walker in dark clothes after sunset; the handbook's clothing and reflector advice points to pedestrians as the night visibility concern.
