When it comes to managing traffic safely in road work zones, flaggers are on the front lines. Their job is critical: protecting both the motoring public and the workers in the work zone. One of the most important decisions a highway department or contractor can make is equipping flaggers with the right tools, namely, STOP/SLOW paddles rather than traditional red flags.

Here’s why STOP/SLOW paddles are the safer and more effective choice:

Clear, Universal Messaging

STOP/SLOW paddles use standardized, universally recognized signage to communicate with drivers. A red octagon that says “STOP” and a diamond or rectangle with “SLOW” leaves no room for confusion. Red flags, on the other hand, can be misinterpreted, especially by distracted or non-local drivers unfamiliar with their meaning. In a split second, clarity matters.

Greater Visibility

STOP/SLOW paddles are designed with high-reflectivity surfaces, and many include retroreflective sheeting or integrated LED lighting for nighttime use. They’re larger, mounted on poles, and easier for drivers to see from a distance compared to small, often limp flags. This early visibility gives drivers more time to react appropriately and slow down.

Promotes Professionalism and Authority

Motorists are more likely to obey clear regulatory signage than a waving red flag. A STOP/SLOW paddle presents a more official, controlled appearance. That added sense of authority can reduce confusion and encourage compliance, particularly in high-speed or high-volume areas.

Better Control of Traffic Flow

STOP/SLOW paddles allow for smoother, more deliberate control of traffic. A flag’s motion-based signaling is imprecise and often left to the interpretation of drivers. With a paddle, the signal is explicit: STOP or SLOW. This minimizes guesswork and improves safety for everyone in the zone.

Compliance with National Standards

The Manual on Uniform Traffic Control Devices (MUTCD) recommends STOP/SLOW paddles as the preferred hand-signaling device. While red flags may still be used in emergencies or low-volume, low-speed situations, they should not be the standard operating procedure. Following MUTCD guidelines also protects municipalities and contractors from liability in the event of an accident.

Reduced Risk to Flaggers

Confusion or delayed driver reactions can lead to dangerous close calls, or worse. Using clear, visible signage gives drivers more time to respond, keeping flaggers out of harm’s way. Every second counts when directing live traffic.

STOP/SLOW paddles aren’t just a better tool; they’re the right tool. They improve communication, reduce risk, and show a commitment to safety and professionalism. Red flags may have been the standard decades ago, but in today’s traffic environments, there’s simply no substitute for the clarity and control of a STOP/SLOW paddle.

Protect your flaggers. Protect your workers. Protect the public. Use the paddle.
