Do I Need to Buy Rental Car Insurance in Michigan?

Michigan Rental Car Insurance: What You Really Need to Know

Renting a car is common, whether you’re traveling, your vehicle is in the shop, or you simply need a temporary replacement. But one of the most common questions we get every summer from our Northern Michigan clients is:

“Do I really need to buy the rental car companie’s insurance?”

The answer is, it depends on your current coverage, and understanding that before you get to the rental desk can save you money and frustration.

Does Your Michigan Auto Insurance Cover a Rental Car?

In many cases, yes, your personal auto insurance policy will extend to a rental car, but only under certain conditions.

If you have a Michigan private passenger personal auto policy, it typically follows you when you rent a vehicle used as a temporary substitute for your own car. That means:

Your liability coverage usually carries over
Your collision and comprehensive coverage may also apply
Your deductibles still apply if there is a claim
Any possible claim surcharges are charged to your auto policy if it pays for a claim

However, your rental coverage is only as strong as your current policy.

If you carry lower liability limits, those same limits apply to the rental car. If you don’t have physical damage coverage on your own vehicle, the rental won’t be covered either for physical damage.

What the Rental Car Company Is Offering You

At the counter, you’ll typically be offered several types of coverage:

Collision Damage Waiver (CDW) or Loss Damage Waiver (LDW)
Covers damage to the rental vehicle
Supplemental Liability Protection
Increases liability limits beyond your personal policy
Personal Accident Insurance
Covers medical expenses for you and passengers
Personal Effects Coverage
Covers belongings inside the vehicle

These are often sold quickly and can feel high-pressure. The key is knowing ahead of time what you actually need.

Key Things to Consider Before You Decline Coverage

1. Your Liability Limits Follow You

If your policy only has $50,000 in bodily injury coverage, that’s exactly what applies to the rental.

For many drivers, this is not enough protection, especially in a serious accident.

2. Your Deductible Still Applies

If you damage the rental car and your policy covers it, you will still be responsible for your deductible.

That could mean paying $500 or $1,000 out of pocket before insurance kicks in.

3. Not All Costs Are Covered

Many Michigan auto policies do not cover:

Loss of use fees charged by the rental company
Diminished value of the vehicle after an accident
Administrative fees

These can add up quickly, even in a minor claim.

4. No Collision Coverage = No Rental Coverage

If your personal vehicle does not carry collision coverage, your insurance will not pay for for any collision damage to the rental car.

In this case, purchasing coverage from the rental company is the safer move.

5. Credit Card Coverage Has Limitations

Some credit cards offer rental car protection, but it is usually:

Secondary coverage
Limited by vehicle type, location, or length of rental
Excluding certain types of claims
May have vehicle ‘value’ limitations
Can limit where you can and cannot drive it

You should never assume you’re covered without confirming the details.

When It Makes Sense to Buy Rental Car Insurance

You may want to strongly consider purchasing coverage if:

You have low liability limits
You do not carry collision coverage
You are renting a high-value vehicle
You want to avoid using your personal policy and risking a rate increase
You want peace of mind with no deductible

When You May Not Need It

You may be comfortable declining coverage if:

You have strong liability limits
You carry collision and comprehensive coverage
You understand and accept your deductible
You’ve confirmed any credit card benefits

The Biggest Mistake We See

The most common issue is not that people decline coverage, it’s that they don’t understand what their policy actually covers before they rent.

That’s when surprises happen, usually after an accident.

Final Thoughts

Rental car insurance isn’t one-size-fits-all. In Michigan, your personal auto policy often provides a solid foundation, but there are still gaps that can leave you exposed.

Before your next trip or rental, take a few minutes to review your coverage or talk with your agent. A quick conversation now can prevent a costly mistake later.
