Arrow Boards are Versatile

Did you know that not only can arrow boards be put up along the road to inform oncoming traffic, they can also go a lot of other places.  For example, there are vehicle and truck mounted arrow boards.  You may see these while driving past a paving project.

You could even see a vehicle mounted arrow board during a snow storm because a lot of times they are mounted to the back of the plow trucks on the highway.  It is pretty hard to not see an arrow board when you are traveling on the road these days.
