In addition to the driver's license, you also need to have a valid insurance policy for your scooter. You can obtain insurance from any insurance company in Turkey.
When driving a 50cc scooter in Turkey, you must obey all traffic laws. These include wearing a helmet, driving on the right side of the road, and using hand signals when turning or changing lanes. You must also be aware of the speed limits, which are typically 50 km/h in urban areas and 90 km/h on highways.
If you are caught violating the traffic laws, you may be fined or even arrested.
