Driving yourself is the best way to get around Doha due to the lack of taxis and public transportation. Qatar's roads are generally new, with lots of wide arterials and traffic circles. Unfortunately, they were not designed well and traffic congestion is commonplace. The lack of public transportation certainly doesn't help. Qatar's drivers do not make things any easier and they can be quite reckless.
Drivers must carry international driving permits or licenses on them at all times. Seatbelts are mandatory and the use of cell phones is strictly prohibited. The speed limit is 60km/hour inside Doha and 100km/hour on highways.
