Drivers licence. With an international driving license or any valid license held for at least 2 full years, you may rent and drive in the most cities. Minimum age 21-25 and maximum age 65-70. International road signs are used.

I recommend to rent a car at least a mid size type car. The engine power of the economy and compact rent a car types is often insufficient. When you are driving in the mountains with the aircon switched on, the engine can hardly provide the power you need. Larger cars often have power brakes, power steering and air bags, which makes them saver. You will probably be driving over large distances and a decent car really pays off then.

Method of payment for a rent a car . Most car rental companies require that you have a credit card for payment. Your credit card is also used as a deposit.

When you are stopped by a police officer then he will ask you for your drivers licence and the car registration. Since you don't have a car registration you should show him your rental agreement.

Before you drive off with your rental car check the car for any damages. If you find any damage or scratches on the rent a car report this to an employee and they will make a note of it on your rental agreement. If you don't report any damages then they may charge you for that damage after you have returned the car.

Additional drivers .Only the person who rents the car is allowed to drive it. If somebody else besides you will be driving the rental car you must mention this during check-in. An additional fee may be charged for a second driver.
