Would not agree with Calimity, if you go throught the light and get snapped, you pay, Qatari or expat, no matter.

But if you went through on the YELLOW, you should be OK. If you did get snapped, you can always go to view the photo and it should show whether yellow or red.

If it was red, well then you wnet through a red light and will have to pay. It matters littel whether you went through by mistake or on purpose (nor, really, should it matter).
