Supervised Driving Log
Teaching Your Teen to Drive
A parent, legal guardian or responsible adult 21 years of age or older, who signed the Affidavit of Liability and Guardianship, must certify that the driver has completed at least 50 hours of driving experience, 10 of which must be at night. The Supervised Driving Log on the following pages should be used to keep track of practice driving time. You can also use the Log to ensure your teen is practicing in a variety of driving environments and weather conditions. This Log will need to be turned in to the DMV when your teen goes to take their road test.
