What adjustment should be made to the spacing of barricades as roadway speed increases on a construction job site?

As roadway speed increases on a construction job site, it is important to adjust the spacing of barricades to ensure the safety of both workers and drivers. Increasing the spacing of barricades allows for adequate reaction time for drivers who may need to navigate through or around the construction zone at higher speeds.

When drivers are traveling faster, their stopping distance increases, meaning they need more time and distance to perceive hazards and react appropriately. By providing greater spacing between barricades, it helps maintain visibility and ensures that drivers can clearly see the construction area in sufficient time to slow down or change lanes safely.

This practice aligns with safety standards that prioritize the protection of both road users and construction personnel. In contrast, maintaining the same spacing or decreasing it would not respond effectively to the increased risks associated with higher roadway speeds, potentially leading to dangerous situations. Random variations in spacing would introduce further confusion and risk, making it harder for drivers to navigate the area safely.
