Read on to learn more about how to add a car to insurance safely.

Why Is Adding a Car to Insurance Necessary?

Here’s a common situation: You’ve just purchased your second car and are wondering whether a new insurance policy would cut it, or you can add this new car to your existing policy for win-win.

The short answer is that adding a vehicle to an existing insurance policy is advantageous when the driver knows what coverage they need for their new car and how the “inclusion” works.

Most insurance companies offer a discount on car insurance for a second car to stay competitive and save on administrative costs.

If you’re interested in adding a vehicle to an existing insurance policy, you should know what to expect:

  • Advantages of insurance on the second car. Many insurance companies provide bigger discounts for insuring more than one vehicle under the same policy.
  • Disadvantages of the 2nd car insurance. Usually, you can’t choose different maximum coverage amounts for different cars if they are listed on one policy.

So, is it cheaper to add a second car to insurance? Yes, it will benefit the insurance company and the driver. Dealing with one company reduces paperwork.

How To Add Another Car To Insurance Policy

Adding another car to insurance is straightforward but requires some preparation. This includes gathering necessary documents, familiarizing yourself with different types of coverage, and setting aside personal time to talk to an insurance agent.

To add a vehicle to insurance, you must first contact your insurance company and inquire about the procedure. You can also do it online.

Adding Car to Insurance Policy Step-by-Step

Obtaining car insurance for a 2nd car may vary depending on the insurance company and your situation. However, there are certain formalities you will encounter in any case.

Step 1 – Contact Your Insurance Agent

You can contact your insurance agency through their website, mobile app, phone call, or in person. At this stage, make sure to gather all relevant information for adding insurance to a new car: the car’s make, model, year of manufacture, VIN, mileage, etc.

Stage 2 – Provide Necessary Information to the Company

The insurance company will ask questions about the new car, your driving habits, and anything they might find valuable to assess risks. Be honest and precise in your answers, as this can affect your insurance terms and the size of the premium.

Stage 3 – Choose the Type of Coverage

You will need to determine the type and level of coverage you want for the new car: liability, collision, comprehensive, or other insurance. Keep in mind that the more incidents the insurance policy covers and the higher the coverage limits, the higher the cost.

Stage 4 – Get a Quote and Compare Prices

After providing all the information, the insurance company will calculate the cost of adding a second car to insurance. At this stage, it would be wise to compare quotes from other companies.

Stage 5 – Complete Adding New Car to Insurance

Making changes to the insurance policy involves choosing when the coverage will take effect and providing proof of ownership of the new car.

Be sure to inquire about discounts, as many companies offer them for policies covering multiple cars and for having a flawless driving record.

At the end, carefully review the received offer regarding insuring a second car. If everything suits you, complete the process by signing the necessary documents.
