Thanks for the info guys. I believe the one I rode was a regular taxi since I hailed him at Matar Qadeem signal and I was riding alone without anybody with the same destination as mine. I hope Karwa would be helpful enough to place informative stickers infront of the dashboard. The taxi number and their help line numbers would be a great if their passengers could see it right away. We can report cheating and reckless taxi drivers on the road.
