Beneficial for your teen to learn the correct way to drive!
My son learned quite a bit from 911 Driving School - Westminster, and he actually taught me some stuff! The drive-alongs were good to help him get familiar with driving. He said he felt it was good to get information from police officers, that it was much better than just taking an online class like one of his friends was doing. He had no problem passing the tests for both his permit and license.
