If you don't hold a driver's license issued in Germany, then you might need to get an International Driving Permit (IDP) in your place of residence in order to rent a car. You should also be aware that if an IDP is required, it won't be valid on its own. You'll need to show your current license your passport and other forms of ID as well. Lastly, it's important that the credit card you used to book the rental vehicle matches the name on your driver's license and passport. A few other things to note for international car rentals are:
- Age restrictions: You must be at least 25 in most countries to rent a car. If you're younger than that, it might still be possible to rent a car but you'll have to pay a Young Driver's Surcharge. Additional restrictions may also apply to the types of cars you can rent.
- Driving limitations: Be sure to read the rules and regulations before sliding behind the wheel. Typically, you can't cross country borders, drive on ferries or off road with a rental car.
