What should the letter height be on a stop/slow paddle used for night flagging?

The correct height for letters on a stop/slow paddle used for night flagging is 8 inches. This specification is important for ensuring that the message is clearly visible from a distance, especially in low-light conditions. The larger letter size allows drivers to see the signals more effectively and react in a timely manner, which is crucial for safety in traffic management scenarios.

Using letters that are too small could lead to confusion or delayed responses from drivers, increasing the risk of accidents. The 8-inch height strikes a balance between visibility and manageability for the flagger, ensuring that they can operate the paddle effectively without it being unwieldy. This size is in line with regulatory standards aimed at maintaining safety and efficiency in traffic control, particularly when visibility is compromised during nighttime operations.
