Have you ever wondered what those 4 numbers in the red diamond mean on the back of semi-trucks, rail cars, or tanks? Theyre codes that tell you what kind of Hazardous Material is being transported!

The 4 digit codes come from the US Department of Transportation (DOT) and the Pipeline and Hazardous Materials Safety Administration (PHMSA).
