Correct answer to question 86 (Hazardous Materials): Replace it before the trip, since a placard that can't be read fails to do its job

Why

A placard that can't be clearly read fails at the one thing it's for, communicating the hazard, so it needs to be replaced rather than left in place or patched over.
