Television reception in the car

[Jez]

It's always been absolutely normal for motorcyclists to use hand signals (and I've had to use some very non approved hand signals to many a half blind car driver!). I've ridden many bikes without indicators (it's legal to have no indicators and of course rely entirely on hand signals but if indicators are fitted then they must work.... allegedly) and you soon get used to it.
Always to be done in conjunction with mirrors of course and the "life saver look back", as they used to call it, when turning left.
