Vehicle markings

Radioactive substance

What does this vehicle marking mean?

A diamond plate carrying the trefoil symbol, showing that the load is radioactive. Materials in this class are transported in heavily engineered containers, so the marking indicates what is present rather than that anything is leaking. At an incident, keep well back and do not handle any part of the load or its packaging. Report the symbol precisely when you call the emergency services.
