A quick note to taxi drivers (mostly private, but sometimes black): The Highway Code does not say that when you put your hazard lights on you can do whatever you like. Double-parking is not okay because your hazards are on; blocking narrow streets does not become acceptable because all your blinkers are on. Hazard lights are exactly that – to warn other drivers that your vehicle is causing a hazard because something is wrong. Not because you want to park where you’re not allowed.
