What does a traffic control flagger do?
At Stone Bridge Traffic Control, our certified flaggers are responsible for safely guiding motorists and pedestrians through and around construction zones, utility work areas, or special event sites. Their role includes using hand signals, traffic paddles, and signage to direct traffic, communicate with crews, and ensure everyone on or near the worksite remains safe. Whether managing high-speed highway traffic or coordinating vehicle flow during a downtown event, our flaggers are trained to keep everything running smoothly and safely.
What equipment and devices do your traffic control flaggers use?
Stone Bridge Traffic Control equips every flagger with professional-grade tools to ensure safety, compliance, and efficiency. This includes:
- MUTCD-compliant stop/slow paddles and traffic signage
- High-visibility ANSI Class 3 reflective vests and weather-appropriate gear
- Two-way radios for clear and constant communication between crew members
- Traffic cones and barricades to clearly delineate work zones and reroute traffic when necessary
All equipment is regularly inspected and maintained to ensure optimal performance on the job site.
How do your traffic control flaggers ensure safety on site?
Safety is the foundation of everything we do at Stone Bridge Traffic Control. Our flaggers follow a strict safety protocol that includes:
- Wearing ANSI Class 3 reflective gear for maximum visibility in all conditions
- Using MUTCD-compliant devices to clearly mark and guide traffic
- Maintaining constant communication with crew members using two-way radios
- Assessing site-specific risks before every project and adjusting traffic control plans accordingly
- Staying alert and responsive to changing conditions, such as traffic volume or weather
By combining industry-best practices with local expertise, our team helps prevent accidents and protects both workers and the public.
What are Automated Flagger Assistance Devices (AFADs)?
Automated Flagger Assistance Devices (AFADs) are remote-operated systems designed to enhance safety by allowing traffic flagging to be managed without a person standing directly in the travel lane. While Stone Bridge Traffic Control primarily provides on-site flaggers, we recognize the value of AFADs for certain high-risk or repetitive traffic control tasks. When appropriate, we can integrate AFADs into a larger traffic control plan to improve safety and reduce exposure for workers in dangerous areas.
What training or certification do your traffic flaggers have?
All of our traffic control flaggers are certified by the American Traffic Safety Services Association (ATSSA)—the gold standard in traffic safety training. In addition to certification, our team undergoes regular hands-on training to stay current with federal and state regulations, MUTCD standards, and industry best practices. This continuous education ensures that our flaggers can confidently manage even the most complex and high-risk traffic control scenarios.
What are the key responsibilities of a traffic control flagger?
Our traffic flaggers serve as the first line of defense in work zone safety. Key responsibilities include:
- Directing vehicle and pedestrian traffic using proper hand signals and signage
- Setting up and maintaining temporary traffic control devices
- Monitoring traffic conditions and adjusting flow as needed
- Communicating with other team members and on-site personnel to coordinate traffic patterns
Responding quickly to unexpected changes, such as accidents or weather shifts, to ensure safety and minimize disruption.
How do your traffic control flaggers handle uncooperative or aggressive motorists?
Our flaggers are trained to remain calm, professional, and non-confrontational in the face of difficult situations. If a motorist becomes uncooperative or aggressive, the flagger will:
- Reassert instructions in a clear and respectful manner
- Maintain a safe distance while continuing to direct other traffic
- Immediately alert their supervisor or call law enforcement if needed
Our team’s training emphasizes de-escalation, safety, and situational awareness, ensuring that conflicts are handled without compromising the safety of the worksite.
When it comes to maintaining safety and efficiency on roadways, you need a team you can trust. At Stone Bridge Traffic Control, we provide professional traffic flagging services to ensure smooth operations for construction sites, events, and roadway projects of all sizes.
