Which statement best captures a foundational element of an efficient traffic control plan?

• A. Visible & Attention getting, Give Direction, Command Respect, and Elicit proper Response at the Proper Time
• B. It is acceptable to leave traffic control devices up overnight if you will return the next day
• C. The plan should ignore pedestrians to keep traffic moving
• D. Motorists will always reduce their speed at traffic control setups

Answer: (A)

The fundamental idea here is that an efficient traffic control plan works because its cues are clear, visible, and timed so road users understand exactly what to do and can act safely. When devices are obvious and attention-getting, drivers notice the setup early and can react in a predictable way. Clear direction means signs, signals, and flagger gestures convey precise actions without ambiguity. The plan also relies on authority and consistency—proper placement, professional behavior, and adherence to procedures—so drivers feel compelled to comply rather than question what to do. Timing ties it all together: cues and restrictions must be coordinated with current traffic flow and pedestrian movement so responses occur at the right moment rather than too soon or too late.

The other statements miss key safety elements. Leaving devices up overnight removes the intended control and creates confusion and risk for anyone traveling through the area. Ignoring pedestrians deprives a vulnerable group of safe crossing opportunities and increases danger. Assuming motorists will always slow down is not reliable; a sound plan establishes expected behavior and works to shape it, rather than hoping it will happen naturally.
