To lease a car, you must have at least a provisional driver's license, which typically requires passing a written knowledge test and a practical driving skills test. Some dealerships may also require lessees to be at least a certain age, such as 18 or 21, and to have a good credit score.
As a learner, you are permitted to drive only when supervised by a licensed driver. Therefore, you cannot independently enter into a lease agreement or take full responsibility for the vehicle.
