What is the maximum taper length for a 1-lane, 2-way taper?

In determining the maximum taper length for a 1-lane, 2-way taper, it is essential to understand that the taper's purpose is to guide traffic into a safe travel path when road conditions change, such as when lane reductions or closures occur. The taper length is crucial for ensuring that vehicles can transition smoothly and safely without abrupt changes in speed or direction.

The maximum taper length of 100 feet aligns with standard traffic control guidelines, which dictate that this length provides adequate space for vehicles to adjust to the changes in roadway layout. This distance allows sufficient time for drivers to perceive and react to the taper, enhancing safety and reducing the risk of accidents.

In contrast, lengths greater than this may lead to confusion and potential hazards, as drivers might misjudge the space or fail to react appropriately, increasing the likelihood of traffic incidents. Therefore, the correct answer of 100 feet reflects an important standard in traffic control design, ensuring that safety is maintained while efficiently guiding vehicles through work zones.
