When we’re driving the highways and byways, we often see trucks with ominous signs that have numbers below the image. What do these signs mean? What should we do if there is an accident involving one of these vehicles?

Members of Anne Arundel-Annapolis Community Emergency Response Team recently attended a presentation on these hazard symbols and how to interpret the data on them. You can also understand these signs by downloading the Emergency Response Guidebook at the link provided below. The application works from both iPhone and Android platforms — search the App Store for “ERG.” The Guidebook is free and provides information on all the signs we typically see while riding the roads and rails.
