What are the minimum dimensions for STOP/SLOW paddles?

• A. 12 inches minimum for the paddle and 3 feet minimum for the staff.
• B. 24 inches minimum for the paddle and 6 feet minimum for the staff.
• C. 18 inches minimum for the paddle and 4 feet minimum for the staff.
• D. 30 inches minimum for the paddle and 5 feet minimum for the staff.

Answer: (B)

The main idea is ensuring visibility and safe distance for the flagger. A STOP/SLOW paddle must be large enough to be read clearly by drivers at typical stopping distances, and the staff must be long enough to keep the flagger out of the traffic lane while still allowing the paddle to be held at a readable height.

The minimums are a 24-inch paddle and a 6-foot staff. A paddle this size is easy to see and read from a reasonable distance, reducing the chance of misreading the signal. A 6-foot staff keeps the flagger back from the roadway, giving time to react to approaching vehicles and minimizing exposure to traffic.

Smaller options would reduce visibility or safety, while larger options exist but aren’t the required minimum.
