When there's no junction, you don't, and in all cases green for traffic implies green for people - but not vice versa. At a crossroads traffic must be blocked in both directions for it to be safe to cross. A red light for traffic in one direction means vehicles travelling in the other direction could still turn left or right through it.

Hmm... green for one implies red for the other, is what I meant to say...

Maybe I should have added a disclaimer: I am not your driving instructor
