Recognize the 6.2 infectious mark

Division 6.2 infectious substances use the biohazard symbol (three interlocking crescents). This is the visual to know. It is part of Class 6, alongside 6.1 toxic substances which use the skull symbol.

When a CDL and placards apply

Whether you need a CDL and whether you must placard depends on the amount transported, the packaging, and the vehicle weight rating, not simply on carrying a biohazard. Many couriers move small, properly packaged quantities under exceptions. Larger or bulk shipments are a different matter.
