There are a lot of reasons to do well in school, but you probably didn't realize that good attendance and a high grade-point average can net a discount on car insurance for drivers in high school or college. While it varies from one insurance provider to the next, you might be eligible (or be able to negotiate) a five to 10 percent discount for teens who maintain a B average, or a 3.0 grade point average on a 4.0 scale [source: Kroll].
There are other educational ways to trim the insurance cost as well. Taking a drivers' education course or safe driving class can knock as much as 15 percent off the insurance bill.
If a teen driver will be attending college away from home and not using the family car, most insurance companies will let you take him or her off the insurance plan until the end of the semester. There might be a distance requirement, typically 100 miles (161 kilometers). If the college is closer, the insurance provider might not allow it, which seems odd – is a teen going to school 80 miles (128.75 kilometers) from home really going to be jaunting around in the family minivan on a daily basis?
