During the setup of traffic control devices, which sequence is recommended?

• A. In the order from the work site to the far road, place devices.
• B. Start with advance warning signs and work down to the work site.
• C. Place all devices without order.
• D. Begin with cones closest to the work site and move outward.

Answer: (B)

The main idea is to set up traffic controls in a logical, progressive way that gives drivers clear warnings and a smooth path into the work zone. Start with advance warning signs placed well ahead of the work area so motorists have time to slow down and prepare to change lanes if needed. Then, as you move closer to the site, add the next devices that guide and contain traffic, narrowing the roadway toward the work zone in a steady sequence. This far-to-near setup creates a safe buffer and predictable movement for drivers.

Starting with cones closest to the work site or placing devices without any order doesn’t give drivers the necessary warning or a clear path, and would lead to confusion and unsafe conditions.
