What actions can be taken to adjust traffic control plans during adverse weather?

Adjusting signs and protocols to accommodate reduced visibility and changing driver behaviors is essential during adverse weather conditions. When weather impacts visibility, such as during heavy rain, fog, or snow, it's important to modify the traffic control plan to ensure the safety of both workers and drivers. This can include implementing additional warning signs, reducing speed limits, and utilizing lighted devices to alert drivers of changed conditions.

By responding to the altered environment, traffic control measures can better guide drivers in navigating through or around the work zone safely. For instance, reducing speed limits acknowledges that drivers may require more time to react in challenging conditions, while enhanced visibility measures ensure that warnings are clearly communicated to motorists.

In contrast, increasing speed limits to maintain flow would likely exacerbate safety issues. Ignoring weather conditions is also unwise, as it neglects the inherent risks posed by adverse conditions. Optionally closing all work until improvements may not be feasible or practical, as certain projects may be critical or time-sensitive, so adjusting the plan rather than halting operations is more advisable.
