The 5 Auto Insurance Coverage Mistakes Drivers Make When Premiums Rise
The problem is that many people respond to rising premiums by cutting the wrong parts of their policy.
That can create a dangerous situation: the premium looks better today, but the policy may leave the driver exposed tomorrow. In a market where claim costs remain elevated and replacement costs continue to pressure auto insurance, coverage decisions need to be made carefully, not emotionally. Triple-I has said replacement costs are expected to outpace CPI in 2025, and LexisNexis reported continued increases in claim severity and a fluid shopping environment.
If you are reviewing your auto insurance right now, here are five of the most common coverage mistakes drivers make when premiums rise—and what to do instead.
Mistake #1: Lowering liability limits too far
This is often the most serious mistake.
When premiums go up, some drivers immediately look at the biggest numbers on the page and decide to reduce liability limits to save money. On paper, that may seem like an easy fix. In practice, it can be a very costly decision.
Liability coverage is what protects you financially if you cause an accident that injures someone else or damages their property. If your limits are too low, you may not have enough protection to cover a serious claim. That can put your savings, income, and future assets at risk. Elevated bodily injury severity is one reason this matters more today. LexisNexis reported bodily injury severity rose 9.2% year over year in its 2025 U.S. Auto Insurance Trends Report.
From a client perspective, this is one of the clearest examples of “cheap insurance” becoming expensive insurance.
A small premium reduction is rarely worth the risk of carrying limits that are too low for today’s claim environment. Medical costs, attorney involvement, and litigation trends can all push liability claims higher than many drivers expect.
A better approach: review whether your liability limits still reflect your income, assets, and exposure. This is an area where stronger protection often matters far more than a small short-term savings.
Mistake #2: Dropping uninsured/underinsured motorist coverage
This is one of the most misunderstood parts of an auto policy.
When people are trying to cut premium, uninsured motorist and underinsured motorist coverage can look optional or less important than collision or comprehensive. But this coverage protects you and your household if you are injured by a driver who has no insurance or not enough insurance.
That matters because not every driver on the road carries adequate protection. If someone else causes the accident and their insurance is insufficient, your own UM/UIM coverage may be one of the most important parts of your policy. Cutting it to save money can leave you exposed at exactly the wrong moment.
This is especially important in a market where many consumers are shopping and some may be focused too heavily on price alone. JD Power’s shopping study shows that consumers are actively looking for relief, but faster shopping does not always mean better coverage decisions.
A better approach: treat UM/UIM as core protection, not a luxury. If you are reducing costs elsewhere, be very cautious about weakening the coverage that protects you from another driver’s poor insurance decisions.
Mistake #3: Removing rental reimbursement to save a few dollars
Rental reimbursement is often one of the first coverages people cut, because it can seem minor—until they actually need it.
If your vehicle is in the shop after a covered claim, rental reimbursement can help pay for a temporary replacement vehicle, subject to your policy limits. Without it, you may be paying out of pocket for transportation while still dealing with your normal household responsibilities, work commute, or business obligations.
That issue is becoming more important because repair timelines can be affected by higher parts costs, labor constraints, and more complex repairs. Triple-I has warned that replacement costs in personal auto are continuing to rise, and tariffs already in place as of early May 2025 were showing negative effects on underlying growth and replacement costs, beginning with personal auto.
For many families, losing access to a vehicle for even a few days is more disruptive than they expect. For newer vehicles with cameras, sensors, and ADAS components, repair timelines can also be more complicated than a traditional bumper or glass claim.
A better approach: before removing rental reimbursement, ask yourself a practical question: If my car were in the shop next week, how would I get around? If the answer is inconvenient or expensive, that coverage may be worth keeping.
Mistake #4: Misunderstanding how deductibles actually work
A lot of drivers respond to rising premiums by raising deductibles. Sometimes that makes sense. Sometimes it does not.
The mistake is not necessarily increasing the deductible. The mistake is increasing it without thinking through what it means at claim time.
A higher deductible lowers premium because you agree to take on more out-of-pocket risk before the policy pays. If you raise that deductible to a level that would strain your budget after an accident, the policy may no longer fit your financial reality. This matters even more when repair costs remain high and small losses can turn into bigger bills than expected. Triple-I continues to project elevated replacement-cost pressure, and LexisNexis has reported ongoing claim severity concerns.
Many people choose a deductible by asking, “How much can I save?” A better question is, “How much could I comfortably pay tomorrow if something happened?”
That is the real test.
A better approach: choose a deductible that gives you a reasonable premium without creating financial stress if you need to file a claim. The right deductible should fit both your budget and your risk tolerance.
Mistake #5: Assuming every policy handles glass and ADAS claims the same way
This is a growing issue, especially for drivers of newer vehicles.
Many consumers still think of a windshield claim or a small bumper claim as simple and inexpensive. But modern vehicles often include cameras, radar, sensors, and recalibration requirements tied to glass, bumpers, mirrors, and other commonly damaged parts. That means a small physical repair can carry a much larger bill than many drivers expect.
AAA found that in the vehicles it studied, ADAS-related costs averaged 13.2% of front collision repairs, 40.9% of minor rear repairs, and 25.4% of windshield replacement costs.
That does not mean every policy covers these situations the same way. Deductibles, glass claim handling, preferred repair networks, OEM parts provisions, and other policy details can vary. A cheaper quote may not always translate into the same claim experience when technology-heavy repairs are involved.
This is one of the biggest mistakes drivers make during aggressive price shopping: they assume they are comparing identical products when they may really be comparing different levels of protection and claims support.
A better approach: ask specific questions about glass coverage, deductibles, calibration-related repairs, and how claims are handled on newer vehicles with ADAS features.
Why these mistakes are happening more often right now
These errors are not happening because people are careless. They are happening because consumers are under pressure.
Premiums climbed significantly over the last several years, and even though the rate of increase slowed in 2024, households are still managing higher insurance costs than they were used to. LexisNexis said overall industry rate levels rose 35% from January 2022 through the end of 2024, while JD Power said shopping activity reached its highest level in the study’s history.
That creates a difficult environment for consumers. People want relief, but the wrong shortcut can create a bigger problem later.
The real goal should not be to strip a policy down until it is as cheap as possible. The goal should be to make sure the policy still protects what matters most while identifying cost savings that do not create unnecessary risk.
What drivers should do instead
If your premium has gone up, this is the right time to review your coverage. But the review should be thoughtful.
Start by asking:
- Are my liability limits still strong enough?
- Am I keeping UM/UIM protection in place?
- Would I need a rental car after a covered loss?
- Could I comfortably afford my deductible tomorrow?
- Do I understand how my policy handles glass and technology-related repairs?
Those questions usually lead to a much better outcome than focusing only on the premium.
In many cases, there may be legitimate ways to improve value without weakening key protections. That might include comparing carriers, reviewing discounts, bundling policies, updating driver or vehicle information, or adjusting deductibles carefully. But the best decisions usually come from a full policy review—not from removing important coverages one by one.
The bottom line
When premiums rise, it is understandable to look for savings. But some coverage cuts are far more dangerous than others.
Lowering liability too much, dropping UM/UIM, removing rental reimbursement, misunderstanding deductibles, and assuming all glass or ADAS claims are handled the same can all leave drivers exposed in ways they may not realize until a loss happens.
In today’s market, the smartest move is not simply buying the cheapest auto insurance policy. It is making sure your coverage is built to handle the real-world cost of accidents, repairs, and liability claims.
That is where a good independent agent can make all the difference.
