How to stay sane while teaching teens to drive
Be aware of your own bad habits.
Before your kid gets behind the wheel, your teen will be watching you drive; even if you don't realize it. Once the child has an image in their head of how the parents drive they'll start to model the same behavior.
So if you've got any bad habits like running red lights, rolling through stop signs, or speeding, this would be the time to stop. Most parents don't find their own bad habits stressful.
