Inspections of Temporary Traffic Control (TTC) work zones should ideally occur during both daytime and nighttime to ensure comprehensive safety and functionality. This practice is critical because work zones can pose unique hazards at different times of the day due to varying visibility and traffic patterns.

During the daytime, visual inspections can help identify issues such as improper signage, obstructed pathways, or challenges with vehicle flow. Nighttime inspections are equally important, as they allow for the assessment of how well lighting is installed, whether reflective materials are visible to drivers, and if safety measures remain effective in lower visibility conditions.

Conducting inspections both day and night ensures that all potential safety hazards are addressed, leading to safer work environments for both workers and road users. Monitoring conditions at varied intervals would not guarantee that all problems are caught in a timely manner, while inspection limitations to only daytime or nighttime would result in gaps in oversight, neglecting the differing challenges presented by each period. Thus, inspecting during both daytime and nighttime optimally covers the diverse circumstances a work zone may encounter.
