Your teen watches how you drive. Set a good example.
Practice behind the wheel as much as possible, including night driving and driving in bad weather conditions.
Enforce the graduated driver’s license provisions in your home for the 1st year that your teen has a license. No passengers under age 20 unless a licensed driver 25 or older is present, and no driving between 11 p.m. and 5 a.m.
Hold onto the keys. For that 1st year of driving, gradually introduce new privileges and use the keys as a point of contact to find out where they are going, who they are going with, and when they will be back.
Teach your teen how to “scan” for hazards. Remind your new driver to keep a “high visual horizon” and to scan the area ahead, behind, and around the car at all times.
It may help to discuss goals with your teen and list them out in the form of a parent / teen driving agreement. Sample formats for these agreements are available through most auto insurance providers.
