RQ stands for Reportable Quantity. It is a marking, not a placard color. The letters RQ appear with the shipping description and markings when a hazardous substance is present at or above a set threshold, which means a spill of that amount must be reported to the authorities. It flags reporting duty, not a new hazard class.
What RQ actually is
RQ is short for Reportable Quantity. Certain hazardous substances have a defined quantity above which a release into the environment must be reported to the authorities. When a shipment contains such a substance at or above that amount, the letters RQ are added to the shipping description and the package marking to flag that reporting duty.
Why it is not a placard
RQ does not change the hazard class or the diamond. A material keeps its normal placard, and RQ rides along in the description and marking as an extra flag. So you will not see an RQ color or symbol on a placard; you see the letters RQ in the paperwork and on the package, paired with the normal hazard information.

Why it matters to a driver
For a driver, RQ is a signal that the load includes a substance serious enough that a spill of that quantity has to be reported, which affects paperwork and emergency response. It is part of the markings and shipping papers system rather than the visual placard system, so it is tested as knowledge rather than as a diamond to recognize.
How to study it
File RQ under markings and shipping papers, not under placards. Remember the expansion, Reportable Quantity, and that it flags a reportable release. The exact list of hazardous substances and their reportable quantities is defined in the regulations and can change, so verify the current values there and in your official manual rather than memorizing numbers from a summary.
