Fronting or not?

We have one car, which my husband and I share, and a son who's desperate to drive. He does not really need a car for getting to work though, only for weekend visits to his girlfriend, 60-odd miles away. If I were to buy another car under my own name, with me also as the main driver on the insurance and him second, but I loaned him the car most weekends, would this be fronting? At present if I want to use our car I often have to get up at 6am to drop my husband off, so it would be handy for me to have another at my disposal?
