Since 1978, Flag Safety Services has been Minnesota and Colorado's most trusted name in professional traffic control. From small projects to major infrastructure, we've been there.
Flag Safety Services was founded in 1978 in Minneapolis, Minnesota, with a simple mission: provide safe, reliable traffic control that protects both workers and the public. What started as a small operation with just a handful of flaggers has grown into one of the largest traffic control companies in the Midwest and Mountain West.
Our founder believed that every work zone deserves professional traffic control, and that belief still drives us today. We've expanded to Denver, Colorado, and now operate with over 500 certified flaggers across two major hub cities and beyond.
But we've never forgotten our roots. We're still family-owned and operated, treating every employee like part of the family and every customer like a neighbor. That personal touch, combined with professional expertise, is what sets us apart.
Everything we do is guided by our core values and commitment to safety.
Safety isn't just a priority—it's our core value. We protect our team, our clients, and the public. Everyone goes home safe, every day.
We do what we say and say what we mean. Honest communication, transparent pricing, and reliable service—every time.
We're family-owned and operated. Our team members are our family, and our customers are our neighbors. We take care of both.
We set the standard for professional traffic control. Continuous training, best practices, and a commitment to being the best in the industry.
Decades of experience, thousands of projects, one commitment to safety.
