This sign means

- yield the right of way to other traffic ✓
- this vehicle is moving slowly
- this vehicle is disabled
- you have the right of way
Answer: A. yield the right of way to other traffic
The sign means yield the right of way to other traffic.
Why this is the answer
The handbook describes a yield sign as requiring you to let traffic on the through road have the right-of-way. If the through road is clear of pedestrians, cyclists and vehicles, you can enter without stopping. If there is traffic, you must slow down, stop if needed, and wait for a safe gap. That is exactly the meaning in the correct answer: yield the right of way to other traffic.
Why the other answers are wrong
- B. this vehicle is moving slowly — A sign about a slow-moving vehicle is not what the handbook's yield-sign rule describes; the yield sign is about letting through-road traffic have the right-of-way.
- C. this vehicle is disabled — A disabled-vehicle sign is not supported by the yield-sign passage, which talks about yielding to traffic on the through road, not about a vehicle being broken down.
- D. you have the right of way — Having the right of way is the opposite of the yield rule, because a yield sign means you must let through-road traffic go first.
Remember it
Think of a yield sign as a give-way reminder: let the through road go first, then take your safe gap.
