A driver’s license is the first step towards independence  —  freedom behind the wheel.

For parents, that driving freedom can come with concerns over insuring their children on the road. Some states allow a 16-year-old to get a car insurance policy on their own, but most states require that you must be at least 18 years old to purchase car insurance, Laura Adams, an analyst for Coverage.com, told Business Insider. 

Therefore, when we are talking about car insurance for a teen, we mean the cost of adding them to a parent or guardian’s existing policy. Unfortunately, a study by Coverage shows that the cost to add a teen to an adult’s car insurance significantly increases the premium. 

Adams says the average parent can expect an 130% increase, or an extra $2,300 in their premium, when adding a teen driver.

According to data from ValuePenguin, the cost for an 18-year-old with a clean driving record on a parent’s policy with Erie is estimated at $2,532 per year, while other larger companies like State Farm, Nationwide, and GEICO all estimate $3,400 or more for coverage. For drivers on the west coast, Mercury Insurance offers coverage under $3,000 per year for a teen driver.

There are many factors that affect your car insurance rates, like:

1. age
2. gender
3. driving experience
4. driving record
5. credit score
6. where you live
7. previous insurance coverage

Adams notes that 16 years old is the most expensive age to insure because someone at this age has little driving experience and statistically, drivers have more accidents at this age. The good news is that premium rates go down with teens as they age, and rates should get more affordable every year.

The death rate among male teen drivers is twice as high as it is for female teens, according to the Centers for Disease Control and Prevention. For this reason, your son will be more expensive to insure than your daughter. 

While some states, like Vermont, allow younger people to be charged more, other states regulate insurance prices differently. For instance, California and Massachusetts do not allow age to be a determining factor.

Auto insurance companies may offer some programs to get a discount on coverage for your teen. In most cases, you can’t “stack” your discounts, or combine them to get a massive discount. But still, you’ll want to ask your provider what, if anything, they offer for teens to earn discounts on their premium.

Good student discount

Adams said the good student discount can save the average parent 8% off their premium for their high school, college, and graduate students up to age 25. Most carriers offer this discount if your child maintains a B average and is a full-time enrolled student.

Away from home discount

This is usually when your teen goes away from home for college and doesn’t take the car with them.

Safe driving training discount

Adams noted some providers reward teen drivers for taking programs to improve their driving skills. This can help you save around 8%.

Monitoring and usage apps

Using a monitoring app can save up to 20% if you’re considered a good driver based on the metrics. Insurers like Progressive, use the app to monitor how hard you hit the brakes, how fast you turn corners, and your average speed.
