If you want to rent a car in Baku, you should keep a few things in mind. First of all, call the chosen car rental company a lot before your trip to receive all the details. Second, don't forget to bring a copy of your driving license, along with your passport. Third, consider your options wisely. The traffic in Baku is pretty harsh and there are almost no road signs. To be honest, this is not a place to start learning how to drive.
