Additional driver
Any person other than the main renter authorized to drive the vehicle — must be named on the rental agreement, license-verified, and typically incurs a daily fee.
An additional driver is anyone other than the primary renter who is permitted to drive the rental vehicle. The rental agreement names them explicitly, the operator verifies their license at handover, and most companies charge a per-day fee (commonly EUR 8–15 in the EU, USD 10–15 in the US) for each additional driver added. Some loyalty tiers and corporate accounts waive the fee for spouses or co-employees.
Allowing an unlisted person to drive is the single fastest way to invalidate every waiver on the contract. If an accident happens while an undeclared driver is at the wheel, CDW, LDW, and PAI all default to "void", and the renter becomes personally liable for the full damage and any third-party claim. This is why operators always check the license at the counter rather than allowing post-hoc additions.
In renviq, additional drivers are stored as related people on the booking — each with their own license number, expiry date, and verification status. The agreement template prints the full list, so the contract reflects exactly who is and isn't authorized at the moment of signing.
