The STOP-SLOW Paddle

In spite of the name "flagger," the preferred device for use by flaggers is not a flag, but the STOP-SLOW paddle. It is preferred that flaggers use the paddle because the messages printed on the paddle - STOP on one side, and SLOW on the other side - provide better guidance to drivers passing through the work area.

The STOP-SLOW paddle is similar to a standard STOP sign: octagonal in shape, at least 18 inches wide, and with letters that are at least six inches tall. The STOP side of the sign should be red, with white letters and a white border. The SLOW side should be orange, with black letters and a black border. If the paddle is to be used at night, it must be reflective.

The STOP-SLOW paddle should be on a rigid handle. The paddle handle should be long enough that if the bottom of the handle is rested on the ground, the sign will be positioned high enough to be seen by drivers in moving or stopped vehicles.

When flagging during an emergency situation at night, a flagger may use a flashlight with a red glow cone in addition to the STOP-SLOW paddle.
