Interesting, which country are you talking about since clearly it does
differ around the world. Essentially in the UK you can turn left or right at
any junction, with or without a traffic signal. Generally the only time you
cannot is when a no left turn or no right turn sign is present. I'm guessing
that the reason the "turn restrictions" tagging has come about is because
most countries are the opposite to yours rather than the same?

Anyway, I agree it sounds like to need a turn_permitted= type tag for your
area.

Cheers
