In Essex you don't indicate at all, regardless of where you are turning off. It's an unwritten rule.
Where I live, nobody indicates at any junction. It isn't safe to indicte when on the phone. Apparently.
Accelerate on the way in, pedal to the metal, punch the roof of the car with your right hand (wearing string backed driving gloves) and cry 'REBEL YELL'.
shut up and listen to 'Guided By Voices'
