Yes, you can easily rent a car at Zurich Airport (ZRH) and drive into Germany, as there are no hard border controls between Switzerland and Germany due to the Schengen Agreement. Most major rental agencies like Alamo, Enterprise, and Sixt allow cross-border travel into Germany without any prior authorization or additional daily fees. However, you must ensure you have the proper documentation: a valid driver’s license and the rental agreement. In 2026, a critical "pro-tip" is to check for low-emission zone (Umweltzone) stickers; if you plan to drive into German cities like Munich or Stuttgart, the car must have a green "4" sticker on the windshield. Additionally, while the car will likely have a Swiss motorway vignette, if you drive on German "Autobahns," no toll is required for cars, but you must be prepared for the higher fuel prices across the border. Always inform the rental desk of your plans to ensure your insurance coverage remains valid for the entire European journey.
