At an intersection controlled by a yield sign, a driver must
  1. yield to all traffic, including cyclists and pedestrians ✓
  2. come to a full stop
  3. yield to cars on the through road
  4. yield to pedestrians on the through road

Answer: A. yield to all traffic, including cyclists and pedestrians

At a yield sign, you must yield to all traffic using the through road, including cyclists and pedestrians.

Why this is the answer

The handbook explains that a yield sign means you let traffic on the through road have the right-of-way. You can enter the intersection without stopping only when there are no pedestrians, cyclists or vehicles on that road. If traffic is there, you slow down, stop if needed, and wait for a safe gap. That matches yielding to all those road users, not just cars or just pedestrians.

Why the other answers are wrong

Remember it

Picture the through road as having the first turn: scan for people, bikes and cars before you move.
