What will happen to my 19 year old son driving my automobile no insurance on quto no license Other driver 16 had insurance?

It's likely that both you and your son will be sued if there are damages to another car or person. He will also face court penalties, and you may face charges for allowing him to illegally operate your car.

The allowing illegal operation charge is not related to him being your son, it can be charged when a vehicle owner allows anyone to operate their car illegally.
