According to the Insurance Information Institute, car insurance companies may offer lowered premiums for married drivers who are combining their policies.

When to Combine Your Car Insurance Policies

If you and your spouse have good driving records and no recent gaps in insurance coverage, you might save more overall by combining policies than by keeping them separate. You could save even more with a multi-car discount if you're insuring multiple vehicles.

If you have different insurers and don't know which one to pick, compare car insurance quotes to see which offers the coverage you need at an affordable price.
