5 Common Traffic Control Mistakes and How to Avoid Them

Traffic control is more than just setting up cones and signs; it's a critical safety measure that protects workers, motorists, and pedestrians. Even small errors can lead to big problems, from costly delays to serious accidents. As a leader in the traffic control industry, we've seen it all. Here are five of the most common mistakes we encounter and our professional advice on how to avoid them.

Mistake #1: Inadequate or Vague Signage

You’ve likely seen it before: a work zone with a single, faded sign that leaves everyone guessing. Incorrect or insufficient signage is one of the biggest hazards. A motorist traveling at 50 mph needs a clear, early warning to safely slow down and adjust. If your signs are confusing, missing, or placed too close to the work area, you’re creating an immediate risk.

How to Avoid It: Always follow the Manual on Uniform Traffic Control Devices (MUTCD) guidelines. Plan your signage in advance, ensuring it’s highly visible, correctly placed, and clearly communicates what is happening ahead. Use bright, well-maintained signs that are easy to read both day and night.

Mistake #2: Improper Spacing and Placement of Devices

Cones, barrels, and barricades aren't just for decoration—they form a protective barrier and guide traffic safely around a work zone. Placing them too far apart can create unsafe gaps, inviting drivers to swerve into the work area. Conversely, placing them too close together can feel like a confusing maze, causing frustration and sudden lane changes.

How to Avoid It: Work with a professional traffic control company to develop a comprehensive plan. We use precise measurements based on road speed, project type, and site conditions to ensure every device is positioned correctly. This creates a clear, predictable path for drivers, which is key to maintaining safety.

Mistake #3: Neglecting Pedestrian and Cyclist Safety

Too often, traffic control plans are designed solely for vehicles, completely overlooking the safety of pedestrians and cyclists. When sidewalks are blocked without a safe detour, people may be forced into the roadway, putting them at serious risk. Failing to provide a clear, accessible path is not only dangerous but can also lead to legal and compliance issues.

How to Avoid It: A complete traffic control plan must include provisions for all road users. Always plan for safe pedestrian walkways and designated bicycle lanes. Use clear directional signs and physical barriers to guide them around the work zone safely.

Mistake #4: Lack of Communication and Training for Flaggers

Flaggers are your frontline safety heroes, but only if they are properly trained and equipped. A flagger who is untrained or not in constant communication with the rest of the crew can create significant risks. Miscommunication about vehicle movements or work zone status can lead to dangerous situations and project delays.

How to Avoid It: Never use untrained or uncertified personnel. Ensure all your flaggers are professionally certified and have a clear understanding of your site-specific plan. Provide them with reliable two-way communication devices and regular safety briefings. Flaggers should always have a clear line of sight and an escape route.

Mistake #5: Failure to Adapt to Changing Conditions

A traffic control plan is not static. Weather, unforeseen road conditions, and unexpected delays can all impact a work zone. Sticking rigidly to an initial plan even when conditions change is a recipe for disaster. A plan that worked perfectly on a sunny Tuesday afternoon might be a safety risk during a sudden downpour or a change in traffic patterns.

How to Avoid It: Regular site inspections and real-time adjustments are essential. Our teams are trained to assess changing conditions and adapt the plan on the fly to maintain safety. This includes adjusting signage, repositioning barriers, or even temporarily suspending work when conditions become too hazardous.
