It is the parent's responsibility to educate their teenage kids how to drive a car correctly. Though it is advantageous to have your teen attend a driving school, the esteem they have for you would certainly support them get at ease while driving. The first concern on parents' mind is where they would begin in coaching their teens on how to drive.
Look out if your teenager is showing unresponsiveness, acting as if they already know what driving is all about. Good-naturedly tell them that not even you are not a perfect driver even with your years of driving knowledge. Make them realize that it is not all about knowing when to go fast and how fast to go. A teenager acting like they got it is usually a warning sign that the parents should look out for. To make sure that he gets the message of how important it is to be careful, tell him that the lives of people in the car with him is in his hands because he is the one driving, even the life of a baby on a Graco Nautilus 3-in-1 car seat matrix.
