The Trailer Mounted Arrowboards
Under this general category, there are two available to consider namely the vertical-mast and folding-frame arrowboards. The former has a display panel that remains vertical all the time but can be rotated to face the traffic. The second type is even more power efficient as it comes with a unique power system that utilizes compact, small, and eco-friendly batteries.
LED Solar Arrowboards
As the name implies, this other type of arrowboard is powered through solar panels with a battery storage bank. The bulbs are not only eco-friendly but are also durable to last for over a decade or two, depending on the specific technology. Better yet, there are display options that include left, right, sequencing arrows, warning bar, double arrow, and caution arrow.
Skid-Mounted Arrowboards
Among various types of arrowboards, these ones are the most energy-efficient signs. They use low power, have a self-contained power supply, and a control module. The skid can be mounted to a truck bed or any rigid footing to keep the arrow stay firmly in place. They are also self-powered and you can select a fixed-position or a pivoting skid.
So these are all the different types. They might be installed differently, but arrowboards do the same thing. If placed properly, they warn and give enough reaction time to any situation to approaching motorists. Finally, you have to keep in mind that the effective placement of arrowboards becomes contingent on sight visibility. Moreover, speed and road geometry must be considered before placement.
