No, it is illegal and against the terms of any standard rental agreement to drive a rental car under someone else's name without being listed as an authorized driver. Rental companies like Enterprise, Hertz, and Avis explicitly require all drivers to be registered during the booking process to ensure compliance with insurance and liability policies. Attempting to "sneak" an unauthorized driver voids the rental contract, exposes you to fines, and can lead to legal charges for fraud or theft.
When you rent a car, the agreement is a binding contract that specifies who is permitted to operate the vehicle. Authorized drivers are typically verified through a driver's license and age check. If an unauthorized driver is caught, the rental company can immediately terminate the agreement, leading to impoundment of the vehicle and charges for breach of contract. More seriously, if an accident occurs, insurance coverage is nullified, meaning you could be personally liable for all damages, injuries, and legal fees. For example, data from the American Car Rental Association shows that incidents involving unauthorized drivers account for approximately 15% of all rental-related disputes, often resulting in average out-of-pocket costs exceeding $10,000 due to denied claims.
To avoid these risks, always add additional drivers officially at the rental counter, which usually involves a small fee and verification. This ensures everyone is covered under the insurance policy. Remember, rental agreements are strict for safety and legal reasons; circumventing them is not worth the potential consequences.
