How to Buy Auto Insurance in 2025

Most states require buying car insurance before you can drive or register your car, but it can be confusing to choose the best car insurance with so many options on the market. From meeting the minimum auto insurance required by your state to figuring out which coverage you should skip, finding the cheapest car insurance takes a little research.

However, there are plenty of ways to simplify the process, including learning how to buy auto insurance online. Whether buying car insurance for the first time or just looking to switch car insurance companies, you can learn how to buy auto insurance below. Then, compare quotes with as many companies as possible to find the best policy for your car.

Determining the Types of Auto Insurance You Need

The first step in purchasing insurance is understanding how much car insurance coverage you need on your vehicle.

The table below shows the types and amounts of coverage each state requires. While some states only require bodily injury and property damage liability car insurance, others also require personal injury protection (PIP) insurance, medical payments (MedPay), and uninsured/underinsured motorist coverage.

​​Minimum Liability Auto Insurance Coverage Requirements by State

As you can see, requirements for mandatory car insurance can be highly different from one state to the next. For this reason, you must know what you’re required to carry on your vehicle before buying car insurance. <

Optional Types of Auto Insurance

Once you’ve learned the coverage you must carry, you should consider purchasing additional coverage on your vehicle for protection.

Liability only covers other individuals and their vehicles in the event of an accident. Therefore, you must purchase collision car insurance coverage if you want coverage for yourself and your car. Collision coverage will help if you’ve been in an accident and your vehicle has incurred damage. <

Similarly, comprehensive auto insurance will help you if your vehicle is damaged in a non-accident-related incident, such as inclement weather or theft.
You may think a liability policy sounds ideal for your vehicle, but you will have to pay for any damages to your car out of pocket. If you lease or finance a vehicle, you will likely be required to carry a full coverage auto insurance policy on your car that includes both comprehensive and collision coverage.

How to Buy Auto Insurance: Online or With a Representative

You can purchase a car insurance policy in a few different ways: online, with a captive insurance agent, or with an independent insurance broker.

More and more people are choosing to buy car insurance online. When you buy car insurance online, you may be able to receive insurance quotes, purchase your coverage, and print ID cards all at once. In this scenario, you do not need an insurance agent to buy a policy.

However, buying online may make it challenging to ask specific questions about car insurance discounts, coverage options, and more.

Buying car insurance with a captive agent allows you to have assistance from start to finish, allowing you to get answers to your questions more easily. But captive agents only work for one company, so you may not be getting the best deal on coverage for your vehicle.

If you choose to purchase insurance with the help of an independent broker, you should be able to find and compare quotes from multiple companies. But brokers often charge fees that could make this a less ideal option.

How to Buy Auto Insurance Online

If you’re interested in buying car insurance online, you should use an online quote tool to find and compare multiple car insurance quotes from many companies at once. While there aren’t any specific search engines for car insurance, online quote tools are a great way to find the best deal on coverage.
Once you’ve narrowed your search and decided on a few companies, you can see if any of them can offer you an even lower monthly or annual rate with car insurance discounts on coverage. Many insurance companies use a variety of discounts to help policyholders save money, and you could save as much as 20% on your coverage if you qualify for a discount.

After you’ve decided on an insurance company, you will need to get some information ready, like:

• Your driver’s license number
• Your social security number
• Your car’s make and model
• Your home address
• An estimate of how many miles you drive per week
• Information on your lease or loan, if applicable
• Names and social security numbers of anyone else who will be on the policy

The company you’ve chosen as your insurance provider may not ask for all the information listed above, but it’s a good idea to have it ready just in case.

Once you purchase your insurance policy, you should print your insurance ID cards and put them with your vehicle’s registration or in another safe location in your car.

Choosing How to Buy Auto Insurance

You can buy car insurance online or with an agent, but be sure to compare quotes from multiple companies so you know you’re not paying too much for coverage.
