<p>A TON of rules, too many to list. </p>
<p>Obviously, abide by state laws</p>
<p>No unnecessary distractions early on - radio, friends, cell phones, food, etc.</p>
<p>Later they could play the radio with reasonable volume, but could not change stations, and they could have 1 friend in the car, and a bottle of water or something to drink.</p>
<p>They are OUR cars, not the kids’, although they each drive one exclusively. We pay for everything, but they have to ask permission to go anywhere except work or school.</p>
<p>All the standard rules regarding curfew and conduct apply.</p>
<p>When I had a car as a teenager, my parents paid the insurance, but I made the car payment, gas and maintenance. It was my car, so I used it as I pleased. My parents DID threaten to take it away for habitual violation of curfew. 
I was 18 at that point, taking 21 hours at CC as an honor student and working part time. We found some middle ground and I got to keep my car.</p>
