Traffic control starts before drivers even reach the work zone. Advance warning signs give them time to slow down, pay attention, and move safely around workers.
Why It Matters:
Drivers moving at highway speeds need time to react. If signs are missing or too close to the work zone, they may not slow down in time — putting your crew at serious risk.
Key Points:
- Use the proper sequence of signs: Road Work Ahead, Lane Closed, Flagger Ahead, etc., based on your traffic control plan.
- Place signs at the correct distances — typically 500 to 1,500 feet in advance, depending on the speed limit.
- Signs must be clean, upright, and highly visible.
- Check signs daily and reposition if needed due to wind, vehicle strikes, or shifting work zones.
- Follow the Manual on Uniform Traffic Control Devices (MUTCD) for layout and spacing.
✅ Good signage gives drivers time — and time saves lives.
Ask the Crew:
- Did we follow spacing requirements for all signs today?
- Are any of our signs damaged, dirty, or blocked from view?
