What is the minimum width of a STOP/SLOW paddle?

The minimum width of a STOP/SLOW paddle is established to ensure visibility and effectiveness in directing traffic. An 18-inch width is sufficient for the paddle to be easily seen by approaching drivers, especially in a work zone where quick action is required.

Paddles serve a critical role in temporary traffic control, as they need to capture the attention of motorists from a distance. A width of 18 inches strikes a balance between being large enough to be recognized without being cumbersome to handle for workers in the field.

Wider paddles, such as those that are 24 or 30 inches, may provide even more visibility in certain scenarios, but the standard minimum of 18 inches is widely accepted to meet safety regulations while ensuring the paddles are practical for use by traffic control personnel.
