What is the minimum length of taper required in a temporary traffic control setup?

The minimum length of taper required in a temporary traffic control setup is essential for ensuring the safe movement of vehicles through construction zones or other areas where roadway conditions are altered. A taper is a transitional area that allows vehicles to adjust to changes in the roadway, such as lane shifts or reductions.

In this context, the correct answer reflects standard safety guidelines which dictate that a taper length of 50 feet is necessary under typical circumstances for effective traffic control. This length provides adequate notice to drivers, allowing them to react appropriately and change lanes or reduce speed without abrupt maneuvers, minimizing the risk of accidents.

By adhering to a 50-foot taper, traffic control setups can effectively guide vehicles through potential hazards, improving overall roadway safety for both drivers and pedestrians. The specified length is based on factors such as vehicle speeds and typical roadway conditions, aiming to ensure a smooth transition in traffic patterns.
