What is the recommended height for vertical panels in work zones?

The recommended height for vertical panels in work zones is 24 inches. This specification is based on industry standards aimed at ensuring visibility and safety for both workers and motorists. The 24-inch height provides a balance that makes these panels easily recognizable without obstructing drivers’ views.

Panels serve a critical function in alerting drivers to changes in road conditions and potential hazards in the work zone. If the panels are too low, they may not be noticed, especially from a distance or by larger vehicles. Conversely, if they are too high, they may block important sight lines or become less effective in conveying appropriate warnings.

By adhering to the 24-inch standard, work zones can maintain a level of clarity and safety that benefits all road users, ensuring that essential information is communicated effectively while minimizing risks associated with work zone environments.
