Weather-Resistant Arrow Boards: Promoting Texas Work-Zone Safety
Texas weather runs from summer heat to spring storms. An arrow board has to stay bright and legible through all of it to keep a work zone safe.
An arrow board only helps if drivers can read it. In Texas that means holding up to blistering summer sun, sudden storms, dust, and wind. A board built and maintained for those conditions keeps directing traffic when the weather is working against it.
What weather resistance looks like
- Sealed housings and connectors that keep out rain, dust, and moisture.
- LED lamps bright enough to read against direct sun.
- A 15-lamp or 25-lamp layout sized to the closure and sight distance.
- Solar or battery power sized to run through short, cloudy stretches.
- Mounting that holds the aim in gusty wind.
Keeping it ready year-round
Weather resistance is part hardware, part upkeep. Clean the panels so dust does not cut brightness, test the lamps, and check batteries and charging before the seasons that stress them. On a high-speed Texas freeway, a 25-lamp board buys extra sight distance so drivers move over earlier, which is the whole point in bad weather when reaction time is already short.
The worst weather is when drivers most need a clear signal, and exactly when a neglected board is most likely to fail. Maintain it before the season, not during it.
