Can you park on double yellows with a disabled badge? No, you cannot. Unless a sign explicitly says you can, assume the answer is always no. Your badge is powerful, but it’s not a force field against the law.
So, next time you see those double yellow lines, just wave at them and drive on. Find a single yellow, a pay-and-display, or a proper disabled bay. Your car, your wallet, and your sanity will thank you. Now go grab that coffee—just not on double yellows, okay?
