Short answer. No. A free loan is purely personal, and Article 1939 provides that the bailee can neither lend nor lease the object of the contract to a third person. Only the members of his own household may use it, unless you stipulated otherwise or the nature of the thing forbids it.

What the law says

The bailee can neither lend nor lease the object of the contract to a third person. However, the members of the bailee's household may make use of the thing loaned, unless there is a stipulation to the contrary, or unless the nature of the thing forbids such use.

Lending a car for free is a commodatum

Article 1933 describes two kinds of loan. Where one party delivers something not consumable so that the other may use it for a time and return that same thing, the contract is a commodatum, and it is essentially gratuitous. Money and other consumables are a simple loan instead. Lending your car falls squarely in the first: the borrower must give back that very car, and you keep ownership throughout. If your friend pays you for the use, it is not a commodatum at all but a lease, and a different set of rules applies to it.

Why the loan does not travel

Article 1939 opens by saying that commodatum is purely personal in character, and the prohibition follows from that. You did not lend the car to whoever happens to need it; you lent it to a person whose driving, care and judgment you were willing to trust. So the article states flatly that The bailee can neither lend nor lease the object of the contract to a third person. Sub-lending is a breach whether or not the third person damages anything, and a borrower who charges someone else for the use is doing something the article forbids outright.

The household exception, and its limits

There is one built-in allowance: the members of the bailee's household may make use of the thing loaned, unless there is a stipulation to the contrary, or unless the nature of the thing forbids such use. His spouse or a son living with him may drive it; his officemate or cousin across town may not. Both escape hatches are worth noting. You can switch the exception off by saying so when you hand over the keys, and it also switches itself off where the thing by its nature is meant only for the borrower personally.

Death ends the arrangement

The same personal character produces a rule that surprises families: the death of either the bailor or the bailee extinguishes the contract. If your friend dies, his household does not inherit the use of your car, and the obligation is to return it. If you die, your heirs may call it back rather than being held to your generosity. This is also the practical answer for anyone in an awkward loan that has quietly gone on for years — the loan is yours to define, and it is far easier to set its terms in writing at the start than to reclaim the thing later.
