The Cost-Effectiveness of Arrow Boards: A Long-Term Investment in Safety
An arrow board is one of the cheapest pieces of work-zone equipment you can own, and one of the most effective at moving traffic safely around a closure.
Drivers need a clear, early instruction to change lanes before they reach a closure. An arrow board gives them that instruction from a long way off, day or night. For the price, few pieces of equipment do as much to keep a work zone from turning into a pileup.
Where the value shows up
- Earlier lane changes mean fewer last-second merges near the crew.
- One board serves job after job for years with basic upkeep.
- LED lamps draw little power and last a long time.
- A 15-lamp or 25-lamp board covers most closure sizes and sight distances.
Choosing 15 vs 25 lamps
A 15-lamp board handles shorter closures and lower speeds. A 25-lamp board throws a larger, more visible arrow that reads earlier on high-speed freeways. If most of your work is on fast rural highways or urban freeways, the larger board usually earns its cost back in the sight distance it buys.
The real return is not the equipment cost saved. It is the crash that never happens because a driver moved over half a mile earlier than they would have otherwise.
