7 years driving experience, can I teach my son how to drive with my car

As long as you are over 21 and has held your driving licence for at least 3 years, you can teach your son to drive your car. However it is important that he gets a couple of lessons with a qualified driving instructor as well so that he can learn the skills needed to pass the practical driving test. It is also important to note that your son will need to be either insured on your current car insurance policy before he can drive your car or get an insurance policy of his own, otherwise he is not allowed to take control of the car.
