When ahackney carriage is not working does it by law have too have its top sign still on the car?
Answers:
No. If they have permanent signs they are supposed to be unlit when the cab is unavailable for hire. You'll find that quite a number have signs with magnetic bases so they can be put on and taken off to suite.
From when my dad used to drive a hackney licensed car all he had to do was make sure the "for hire" sign wasn't lit. As far as I know the taxi sign on top could still be lit, it's a valuable advert.
