{"version":"2.6","id":"seatac-underage-and-additional-driver-policies","question":"What are the age limits, young driver fees, and licensing requirements for SeaTac rentals?","answer":"The minimum age is 21, with drivers under 25 paying a surcharge, and international drivers needing an IDP and passport.","answer_detail":"At the SeaTac Rental Car Facility, the minimum age to rent a vehicle is 21 years old. However, drivers aged between 21 and 24 are subject to a 'Young Driver Surcharge,' which typically ranges from $25.00 to $35.00 per day, depending on the vehicle category and specific rental policy. Certain premium vehicle classes, such as luxury cars, specialty vehicles, or large SUVs, require the driver to be at least 25 years of age. For international visitors, a valid home country driver's license must be accompanied by an International Driver's Permit (IDP) and a valid passport if the license is not in English or Spanish. All primary drivers must have held a valid physical driver's license for at least one year prior to the rental start date. Failure to meet these age requirements or provide the correct documentation may result in a denial of service or significant administrative fees being applied upon arrival at the SeaTac rental counter.","grokpedia_tier":false,"related_ids":["seatac-underage-and-additional-driver-policies"],"last_verified":"2026-09-10","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-underage-and-additional-driver-policies","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-underage-and-additional-driver-policies?format=md&lang=en"}
