There are lots of reasons couples decide to get married; love, loyalty, and lower car insurance rates.
Married drivers can score cheaper auto insurance as their insurability risk is much lower. Unmarried drivers, meanwhile, pay 20% more on their monthly premiums.
As men are the leading gender when it comes to fatal car accidents, buying car insurance as a family poses less risk for the insurance companies. Families can also insure several vehicles under the same plan, therefore reducing costs that come from insuring individual cars.
