TTCP is required for any work within the ROW that affects traffic flow. Which statement best describes this requirement?

• A. TTCP is optional for small projects
• B. TTCP is required whenever traffic flow is affected
• C. TTCP is only required for nighttime work
• D. TTCP is only required for detours

Answer: (B)

Any project within the right-of-way that could alter how traffic moves requires a Temporary Traffic Control Plan. The TTCP lays out how signs, devices, barriers, and personnel will guide traffic safely around the work and keep both motorists and workers protected. This is why the best description is that a TTCP is required whenever traffic flow is affected—because the plan is triggered by any change to traffic movement, not by project size, time of day, or by detours alone. It isn’t optional for small projects, it isn’t limited to nighttime work, and it isn’t only for detours; it applies to any situation that impacts how traffic moves, including lane closures, changes in access, or pedestrian and cyclist considerations within the work zone.
