Which statement about leaving traffic control devices up overnight is correct?

• A. It is allowed to leave traffic control devices up overnight
• B. It is never allowed to leave traffic control devices up overnight
• C. It depends on device type
• D. No, it is not acceptable to leave traffic control devices up overnight

Answer: (D)

Temporary traffic control devices are placed only for active work and to guide drivers through a construction zone. Once the work has ended or there is no ongoing operation, leaving those devices in place overnight can mislead drivers, clutter the roadway, and create safety or liability issues because the message they convey may no longer reflect current conditions. Therefore, the proper practice is that it is not acceptable to leave traffic control devices up overnight. Options suggesting it’s allowed or depending on device type don’t fit because the standard goal is to avoid outdated or misleading guidance when no work is actively occurring. The occasional overnight continuation would only be appropriate if there is an authorized, ongoing operation through the night; otherwise, they should be removed.
