Do placards and hazard warning labels look exactly identical on tests?
Almost. Placards and labels use the same diamond shape, colors, symbols, and class numbers, so they look the same on a test. The main difference is size and where they go: placards are large and mark the vehicle or bulk container, while labels are small and mark individual packages.
Same design, different size and place
A label and the matching placard share the same hazard-class design: the same color, the same symbol, the same class number. So if you can recognize the placard, you can recognize the label. The difference is that placards are large and go on the vehicle or bulk container, while labels are smaller and go on packages.
Why the test can use either
Because the visual is the same, a question may show a small label or a large placard and expect the same answer. Read the diamond the same way every time: color, symbol, class number. The size does not change the meaning.
