I don't think I've ever seen a sign like that at traffic lights which weren't temporary, in which case it would depend on what I could see. If it was a multiple crossroads and I couldn't see into the line, I'd wait. It could be that the workies have put another set of traffic lights down the road to the left, and just put the lights you're seeing where it's convenient.
But if there were definitely no lights down the road, I'd go for it. Also, if I was on my test I'd probably wait as well. They'll fail you if they think you've run the red, but you'd hopefully only get a minor for not going if you should have.
