I specifically tried not to make you feel as if you've posted something unrequired but you have to face reality; just how many of these signs do you see in Pakistan, on the normal roads, the highways or the motorways? Not more than half of them even. Many are pretty obvious and easy to understand too. If you were one of the unlucky ones who had to go through a driving test (as many don't) to get a license, you'd most probably be knowing that that is the only time you need to know these signs for that is part of the (horrible) exam.
