Even if you add a young driver to your policy, your rates will likely go up more than before.

How to get a cheap car insurance policy at 18

If you want to add an 18-year-old to your policy, it is advisable to compare insurance quotes from different companies. To know what company provides the best deals for your needs and budget. Explore different discount opportunities and consider reducing some coverage to save more money. Increase your deductible.

You can ask your insurance agent to give you quotes for different deductible levels. Decide on the best one, and keep in mind that a young driver is likely to be more into something than an adult driver. Also, comprehensive and collision insurance are very cheap if your car is very cheap to replace or repair. Avoid luxury cars and stay away from sports cars if you want auto insurance rates to be affordable.
