"Teens are very likely to pick up the habits of their parents,” says J.C. Fawcett of the Defensive Driving School. “A parent should think about. Do I cuss at other drivers while driving? Do I speed? Do I tailgate? The training that comes from students observing their parents is very powerful. If a parent attempts to change their habits only when their teen is learning to drive, it's probably 10 years too late."
Naturally, insurance companies use your driving past as an indicator of how you will drive in the future. It can be difficult to find affordable car insurance if you have a checkered driving history. While it’s very unlikely you will find an insurance company that won’t increase your premium after an at-fault accident or other violation, the degree of the rate increase will vary by company. Let’s compare rate increases for some common violations across major insurance companies.
Credit score: This can be a main factor for insurers in states that allow it.

Keep your credit score in the acceptable range to keep your premium affordable.
