The requirements will vary between companies and they should always be consulted directly, however some things to consider when renting a vehicle for your stay are: Driving licence- You will need a current, valid Driver’s Licence, held for a minimum of one year and any necessary international driver's permits. Age Restrictions- There may be minimum age restrictions to rent a vehicle. The minimum age requirement varies depending on the vehicle and pick-up location. Mileage Policy- You may be required to estimate your mileage and fees may apply if you exceed this estimate. It is for example a 162 mile journey from Glasgow Airport to Grantown.
