Regulatory, Lane & Parking SignsStandalone practice
A red octagonal sign displays the word STOP. What response is required?
Correct answer: Stop fully, yield to conflicting traffic, then go when safe.
Why
Come to a complete stop at the required stop location. Yield to traffic or crossing users that would conflict with your movement, then proceed only when safe. Slowing without stopping does not satisfy a STOP sign.
