Generally, only the person named on the policy and rental agreement is covered to drive a courtesy car. While policies can vary, the default position of most insurers and dealerships is to restrict driving to the primary policyholder for liability reasons. Attempting to let another person drive, even a named driver from your own policy, could void the insurance coverage for the courtesy vehicle.
The insurance for a courtesy car is typically a temporary extension of the garage's policy, designed specifically for the customer while their vehicle is being serviced. This coverage is not the same as a standard rental car agreement where you can add additional drivers for a fee. The key document is the loan agreement you sign when accepting the keys. This contract will explicitly state who is permitted to operate the vehicle.
Before assuming anything, you must take two steps:
If an unnamed driver gets into an accident, the garage's insurance will likely deny the claim. This could leave you personally liable for all damages to the courtesy car. Some dealerships may offer a more flexible policy, but this is the exception, not the rule. Always err on the side of caution and confirm permissions in writing.

Nope, almost certainly not. When I picked up my loaner last week, the guy at the dealership was very clear: "This is for you only." The is tied directly to you as the customer they're servicing. Letting your spouse or kid drive it is a huge risk. If there's a fender bender, you'll be on the hook for the whole repair bill. It's just not worth the hassle. Always ask, but expect a "no."

It's a definite maybe, but you have to check. My husband was able to drive our courtesy car once because I specifically asked when I dropped my SUV off. The service manager said their allowed one additional licensed driver living at the same address, but it had to be noted on the agreement. It completely depends on the dealership's rules and their insurance provider. The only way to know is to ask the right person before you drive off the lot.

From a practical standpoint, the rule exists to manage risk for the business. A courtesy car isn't a standard rental; it's a convenience with very narrow terms. Think of it like this: the garage's policy covers the vehicle when it's in the hands of their verified customer. Introducing an unknown driver—even your named driver—adds a variable their underwriters haven't approved. This is a common practice across the industry to keep their costs and liability low.

I learned this the hard way. My son, who's on my , needed to run an errand and took the courtesy car without me asking first. Thankfully, nothing happened, but when I mentioned it later, the service advisor told me I'd been lucky. He said their coverage is voided if an unauthorized driver is behind the wheel. It doesn't matter what your personal policy says; the loaner car's rules are what count. Always assume it's a one-driver car unless you get a confirmed "yes" in writing from the service manager. It’s a simple question that can prevent a financial disaster.
