What hazmat placard is half yellow and half white class 7?
That is the radioactive placard, Class 7. It is yellow on the top half and white on the bottom half, with the radioactive trefoil symbol and a 7 at the bottom. The yellow-over-white split and the trefoil are what make Class 7 easy to spot once you know it.
Yellow over white means Class 7
The radioactive placard is split with yellow on top and white on the bottom, carries the three-bladed trefoil symbol, and shows a 7. No other hazard class uses that exact yellow-and-white split with the trefoil, so it is a reliable visual once you have seen it.
The I, II, III labels you may also see
On packages, radioactive labels are marked RADIOACTIVE I, II, or III, a category that reflects the radiation level, from I (lowest) to III (highest). The vehicle placard itself is the yellow-and-white diamond with the trefoil and the 7. Radioactive transport is tightly regulated, so verify details in your official materials.
