What is the speed limit typically posted in construction zones?

In construction zones, speed limits are typically reduced to ensure the safety of both workers and drivers. These reduced limits, often 10-15 mph less than the regular speed limit, are put in place to accommodate the potentially hazardous conditions present, such as narrow lanes, changed traffic patterns, and the presence of workers and equipment. The purpose of lowering the speed limit is to give drivers ample time to react to any sudden changes or obstacles and to protect the construction crew working in the area. This practice prioritizes safety, which is critical in environments where human and mechanical activities intersect.
