Prohibition signs are mostly red and tell you what you must do or must not do. Warning signs are yellow diamonds that tell you what's coming, like a curve, an intersection or a crossing, so you can slow down and be ready to stop.

Know the rule

Stop sign: come to a full stop (wheels completely stopped) behind the stop line or crosswalk; if there is neither, stop before entering the intersection.

You see a yellow diamond with a red octagon and an arrow. It's a Stop Sign Ahead warning: begin slowing now so you can stop fully at the sign that's coming.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

A full stop at a stop sign means what, according to the manual?
  1. The wheels must completely stop moving
  2. The vehicle must slow to a crawl
  3. The vehicle coasts through slowly
  4. The driver taps the brake once

Answer: The wheels must completely stop moving

A full stop requires the vehicle's wheels to completely stop moving.

What does a yield sign require a driver to do?
  1. Stop fully behind the line before every entry
  2. Keep speed and merge into the first gap
  3. Slow down and let right-of-way traffic cross
  4. Stop only when a pedestrian is waiting

Answer: Slow down and let right-of-way traffic cross

A yield sign means slow down and allow traffic that has the right-of-way to cross before entering.

At a stop sign with no stop line and no crosswalk, where must you stop?
  1. Even with the stop sign post
  2. 15 feet before the stop sign
