Increase your business traffic! Motorists in Indiana rely on the familiar blue interstate highway signs for service and recreational information. These blue signs advertise logos for GAS, FOOD, LODGING, CAMPING and ATTRACTION businesses. Logo Signs are placed preceding exit ramps, contain directional information, and are very helpful to guide motorists to your door. Indiana Logo Signs have been beneficial for businesses, with many reporting a 25 percent increase in customer traffic after their logo was displayed.
