The renter doesn't have the authority to let somebody borrow it. So the driver doesn't technically have permission from the owner to drive it.Now as it applies to a rental car almost every rental car company requires any person who is going to drive the car be listed on the contract. In short, the primary renter is taking a huge risk if they allow someone not on the contract to drive the car. It depends on jurisdiction and the state the vehicle is registered in etc. The driver will need to possess a valid driver's license, be at least 25 years of age and be subject to any applicable driving record check. Anyone with a suspended license cannot legally drive, and Budget requires that all renters have a valid, active license. If a driver is licensed in a state other than Michigan, the department may submit a copy of the driver's out of state motor vehicle record to RMI for review. Our attorney says it's best to purchase the "optional" insurance coverage offered with a purchase of a rental car out of state. What should I bring to pick up my rental car?
