How to save money on car insurance as an 18-year-old

If you want to save on car insurance for a teen, there are a few steps you can take to lower the costs:

1. Join an existing policy

If you still live at home with your parents or other family, you can save on car insurance by joining their policy rather than getting your own coverage. Their premiums will still go up, but it will be cheaper than if you bought a separate policy.

2. Take advantage of discounts for teen drivers

Discounts can help you lower your rates, and teen drivers who are also full time students can typically earn a discount for maintaining above a certain GPA, or for taking a driver’s education course. Some companies also offer special programs designed for teen drivers that can earn you even more savings. 

3. Compare quotes from multiple companies

Getting quotes from multiple companies can help you find the coverage you need at the cheapest price. You may be able to spend a lot less at one company than another and still get the same coverage.

4. Drop comprehensive and collision

You can consider dropping comprehensive and collision coverage if the car your teen is driving wouldn’t be worth repairing or replacing in the event of an accident. You can keep comp and collision coverage on other cars on your policy, but dropping those coverage for one car can earn you significant savings.
