Conventional traffic signs include which of the following?

• A. Speed limit signs
• B. Stop and yield signs, etc
• C. No smoking signs
• D. Handicap parking signs

Answer: (B)

Conventional traffic signs are the standard road signs that regulate how drivers move and what actions they must take. Stop and yield signs are classic examples of these regulatory signs because they directly control right-of-way: a stop sign requires a full stop, and a yield sign requires slowing and giving way to other traffic. Their bold shapes and colors are designed for instant recognition, so a driver can respond quickly to maintain safety at intersections, including in airport roadways where vehicle movement is busy. Other items like no smoking signs and handicap parking signs aren’t traffic-control signs that govern how vehicles move; they relate to safety rules or parking eligibility within a facility rather than directing traffic flow. Speed limit signs are also regulatory signs in the road system, but stop and yield signs illustrate the core idea of traffic control guidance that conventional signs provide.
