Most think it’s quite unfair for a driver to pay twice the amount for a car insurance premium in one state versus another.

While most people know your age and driving history determines how much you pay for car insurance.

Another chief factor is the state you reside in.

According to the National Association of Insurance Commissioners, average car insurance costs vary by state based on regulations, while car insurers give you a price quote based on those differences.

And one state may have higher instances of claims history and higher minimum coverage requirement levels while another doesn’t.

The type and coverage limits will influence your premium.

For example, the difference between full coverage (comprehensive insurance and collision) and minimum property damage liability and bodily injury liability will be significant.

Many states require you to have personal injury protection or PIP coverage amounts and medical payments.

This, too, will influence your final premium.

Further below, we will explain personal injury protection and medical payments, common coverage levels. 

Personal Injury Protection (PIP)

Personal injury protection, sometimes called PIP, is the portion of your policy that provides medical expenses and work-loss coverage for you and your passengers in the event of a vehicle accident.

PIP covers you no matter who is at fault.

Here are items PIP will cover:

  • Medical bills
  • Surgical fees
  • Lost wages
  • Rehabilitation fees

And if you live in any states below, you will be required to carry PIP along with liability:

As you can see, many expensive states to insure a vehicle are on the list.

Since you must carry PIP in the listed states, your overall car insurance premium will be higher than average. 

Basic policy breakdown by coverage type. Bodily injury, property damage, medical payment, and uninsured motorist.Note: Illustrated above is a breakdown of a policy. The area we are referencing too is the “medical payment” part of the policy. Some states require you have medical payment (MedPay) or personal injury protection (PIP). If you are required by your state to carry either coverage, it makes up a significant portion of your policy. And, in turn, raising your car insurance premium.

Next, we will explain medical payments coverage and the slight difference from PIP.

Medical Payments Coverage

Medical payments coverage, sometimes called MedPay, is intended to cover medical costs in the event of an accident, no matter who is at fault.

Normally, your health insurance will pay for the necessary medical benefits and expenses.

MedPay will “fill in the gaps” for cases where there are low limits or high deductibles.

The difference between MedPay and PIP is Personal Injury Protection takes it a step further and covers lost wages where MedPay doesn’t.

MedPay coverage is required in the following states:

  • Pennsylvania
  • Maine
  • New Hampshire

Medical payments cost less than PIP for the same protection.

To get $10,000 in medical payments coverage, you will pay from $4 to approximately $24 per month.

For example, in Maine, the minimum medical payments are $2,000, which will cost $8 a month or thereabouts.

PIP normally has higher required limits and will cost more.

In Florida, PIP is 10 to $15 a month, depending on the deductible. 

Frequently Asked Questions 

Do I need to compare quotes if I move out of state?

Short answer – yes. Where you live is going to be a big factor insurers use to determine your premium. As part of your financial planning, if you are moving out of state, you want to compare quotes with local, regional, and national insurers in the area you plan to move.

Even if you are making a local move, it is always a good idea to comparison shop with your current insurance provider and others to find the best rate.

Why is my premium higher than my state’s average?

You could have a poor driving history, low credit score, history of claims, a lapse in coverage, expensive car, or you are a younger person.

Location within the state will make a difference.

If you live in an urban city, you are likely to pay more than someone residing in suburban areas.

How expensive or inexpensive your car insurance policy will depend on your driver profile (the factors discussed) and your past driving history.

If you want to reduce your premium, comparison shop, talk to a licensed insurance agent or a financial advisor.

What else can affect my auto policy?

One of the most overlooked items is the insurance credit score when people are shopping for auto insurance.

A poor insurance credit score will affect the price you pay for a premium.

If you take out a loan or use more of your credit line, thereby reducing your overall score, an insurer can raise your premium at renewal.

Depending on state and insurer, the difference between a poor and an excellent credit score can be over 30% on average.

If you reside in California, Hawaii, Massachusetts, or Michigan, credit scores to determine a premium isn’t lawful.
