As the roadway speed increases at a construction site, how should the spacing between cones and barricades be adjusted?

When the speed of vehicles increases in a construction zone, the spacing between cones and barricades should be increased to effectively guide drivers and ensure their safety. Higher speeds mean that drivers have less time to react to sudden changes in the roadway conditions, such as construction activities or obstacles.

Increasing the spacing allows for a clearer sightline, which is critical for driver awareness and can help in reducing the likelihood of accidents. Drivers need sufficient distance to perceive and respond to the warning devices, especially when traveling at higher speeds. If the cones and barricades are too close together, drivers may not have adequate time or space to safely navigate through the construction area. Thus, increasing the spacing provides better guidance and promotes overall safety for both the motorists and the construction workers.
