Question:
You are asking about the ruling on a woman riding alone with a non-mahram driver; is it permissible or not?

Answer:
This is not permissible, and the warning has been repeated that it is not permissible for a woman to ride with a driver who is not one of her mahram (relatives one may not marry); because this is a form of forbidden seclusion; because the Prophet (peace and blessings be upon him) forbade a man from being alone with a woman who is not one of his mahram, and it is most likely that this leads to the presence of Satan by causing them to fall into fitnah (trial, discord or temptation) and corruption; so this is one of the means of corruption. And Allah the Exalted said: "And do not approach zina (unlawful sexual intercourse)," and this is a prohibition of the means that lead to falling into zina, among which is the seclusion of a man with a woman who is not lawful for him, whether in a car, in a house, or in any place, except if she is with one of her mahram, or with others whose presence removes the seclusion and makes it a group. And her riding with him in the car is more dangerous than his being alone with her in a house or elsewhere, because in the car he can control it and flee with her without her consent, so corruption occurs, because in the car he has authority over her, and the woman is weak, so he may flee with her or threaten her or the like of that. Yes. May Allah reward you with good, and may He do you good
