Here’s where it gets ironic. The Blue Badge is meant to help you access shops and services, but you cannot park on double yellows if it would cause an obstruction. You know, like blocking a driveway, a bus stop, or a fire hydrant.
Also, forget about parking on zigzag lines near pedestrian crossings—those are strictly off-limits for everyone, badge or not. And please don’t park on a red route in central London. The penalty is brutal (like, £130 brutal).
What About Single Yellows?
Single yellow lines are actually easier than double yellows with a Blue Badge. You can park on those for up to three hours too, but the twist is: single yellows already have a time limit for everyone else. The Blue Badge just gives you an extra boost if the normal restriction is shorter.
But honestly? The double-yellow rule is the one people mess up. I once saw a guy park his van on double yellows for six hours with his badge on the dash. He came back to a ticket and a wheel clamp. Ouch.
