10 Common Auto Insurance Mistakes That Could Be Costing You Money
According to the Insurance Information Institute, American drivers spend an average of more than $1,700 annually on auto insurance premiums. Yet many policyholders unknowingly pay hundreds of dollars more than necessary due to common mistakes that are entirely avoidable. From failing to shop around for competitive rates to overlooking valuable discounts, these errors can significantly impact your household budget. Understanding these pitfalls—and how to avoid them—can help you secure adequate protection while keeping more money in your pocket.
1. Not Shopping Around for Better Rates
One of the most costly mistakes drivers make is staying with the same insurance company year after year without comparing rates. According to a 2023 J.D. Power study, auto insurance premiums increased by an average of 12.6% that year, with some insurers raising rates more aggressively than others. The variation in pricing between companies for the same coverage can be substantial—sometimes hundreds of dollars annually.
Insurance companies use different algorithms and weighting systems to calculate risk, which means the same driver with identical coverage needs may receive vastly different quotes from different insurers. The National Association of Insurance Commissioners recommends comparing at least three to five quotes when shopping for auto insurance.
Key Insight: Industry data suggests that drivers who compare rates every 12 to 24 months are more likely to find savings than those who auto-renew without reviewing their options.
2. Choosing the Wrong Deductible
Your deductible—the amount you pay out of pocket before insurance kicks in—directly affects your premium. Many drivers default to a low deductible ($250 or $500) without realizing how much they could save by choosing a higher one.
However, selecting a deductible that’s too high can also be problematic if you can’t afford to pay it when an accident occurs. The Insurance Information Institute advises choosing a deductible that balances affordable premiums with a manageable out-of-pocket expense in the event of a claim.
| Deductible Amount | Typical Annual Premium Impact | Best For |
|---|---|---|
| $250 | Higher premiums | Drivers who want minimal out-of-pocket costs |
| $500 | Moderate premiums | Balanced approach for most drivers |
| $1,000 | Lower premiums | Drivers with emergency savings |
| $2,000+ | Lowest premiums | Low-risk drivers with substantial savings |
3. Overlooking Available Discounts
Insurance companies offer numerous discounts that many policyholders never claim simply because they don’t ask. Common discounts that go unclaimed include:
- Multi-policy bundling: Combining auto with home, renters, or life insurance
- Safe driver discounts: For maintaining a clean driving record
- Low mileage discounts: For drivers who commute short distances or work from home
- Good student discounts: For young drivers maintaining a B average or better
- Defensive driving course completion: Many states require insurers to offer this discount
- Vehicle safety features: Anti-lock brakes, airbags, anti-theft systems
- Payment discounts: Paying annually instead of monthly, or enrolling in autopay
- Affinity group discounts: For members of certain professional organizations, alumni associations, or employers
According to the National Association of Insurance Commissioners, policyholders should review their eligibility for discounts at every renewal period, as circumstances change and new discount programs become available.
4. Having Inadequate Liability Coverage
State minimum liability requirements are designed as a baseline, not a recommendation for adequate protection. Many states require liability limits as low as 25/50/25 (meaning $25,000 per person for bodily injury, $50,000 total per accident for bodily injury, and $25,000 for property damage).
These minimums may prove insufficient in a serious accident. Medical costs, lost wages, and property damage can easily exceed state minimum limits, leaving you personally responsible for the difference. The Insurance Information Institute suggests that drivers consider liability limits of at least 100/300/100, particularly those with assets to protect.
Understanding Liability Coverage Gaps
If you’re found at fault in an accident and damages exceed your policy limits, you could face:
- Wage garnishment
- Seizure of assets including savings accounts
- Liens placed on your home
- Long-term financial consequences
5. Not Reviewing Your Policy Annually
Life circumstances change, and your auto insurance should reflect those changes. Failing to update your policy can result in paying for coverage you no longer need or lacking coverage you require.
Events that should trigger a policy review include:
- Paying off your vehicle loan (you may no longer need gap coverage)
- Moving to a new address (rates vary significantly by location)
- Changes in commute distance or work-from-home status
- Adding or removing drivers from your household
- Purchasing or selling a vehicle
- Major life events such as marriage, divorce, or retirement
- Your teen driver graduating from college or moving out
6. Insuring an Older Vehicle with Full Coverage
Comprehensive and collision coverage make financial sense for newer vehicles, but maintaining full coverage on an older, lower-value vehicle may not be cost-effective. The general guideline suggested by consumer advocacy groups is to consider dropping comprehensive and collision coverage when the annual premium for these coverages exceeds 10% of the vehicle’s actual cash value.
You can check your vehicle’s current market value through resources such as Kelley Blue Book or the National Automobile Dealers Association (NADA) Guides. If your car is worth $3,000 and you’re paying $600 annually for comprehensive and collision, you may want to reconsider that coverage.
Important Consideration: Before dropping comprehensive or collision coverage, ensure you have sufficient emergency savings to replace or repair your vehicle if necessary.
7. Failing to Report Mileage Changes
Your annual mileage is a significant factor in determining your premium. Drivers who commute long distances pay more because they’re on the road more often, increasing their exposure to potential accidents.
Since the shift toward remote work accelerated in 2020, many drivers have significantly reduced their annual mileage. If you’ve transitioned to working from home, retired, or otherwise reduced your driving, notifying your insurer could result in lower premiums.
Some insurers now offer usage-based insurance programs that track actual mileage through a smartphone app or plug-in device. According to the National Association of Insurance Commissioners, drivers who travel fewer than 7,500 miles annually may benefit most from these programs.
8. Neglecting to Bundle Policies
Most major insurance companies offer multi-policy discounts when you purchase more than one type of insurance from them. Bundling auto insurance with homeowners, renters, or umbrella insurance can result in savings on both policies.
According to industry data, bundling discounts typically range from 5% to 25% depending on the insurer and the types of policies combined. However, bundling isn’t always the cheapest option—in some cases, purchasing policies from separate specialized carriers may cost less even without the bundling discount.
The best approach is to compare the total cost of bundled policies against the combined cost of separate policies from different insurers.
9. Letting Your Coverage Lapse
Allowing your auto insurance to lapse—even briefly—can have expensive consequences. Insurance companies view coverage gaps as a red flag indicating higher risk, which typically results in higher premiums when you reestablish coverage.
Additionally, driving without insurance is illegal in most states and can result in:
- Fines and penalties
- License suspension
- Vehicle registration suspension
- SR-22 filing requirements (a certificate of financial responsibility that increases costs)
- Personal liability for any accidents that occur during the lapse
If you’re having difficulty affording your premium, contact your insurer before your policy lapses to discuss options such as adjusting coverage levels or payment plans.
10. Not Understanding What Your Policy Covers
Many policyholders don’t fully understand what their auto insurance covers—and more importantly, what it doesn’t cover. This knowledge gap can lead to both overpaying for unnecessary coverage and being underprotected in critical areas.
Common Coverage Misunderstandings
Rental car coverage: Your personal auto policy may extend to rental cars, making the rental company’s insurance unnecessary. However, this varies by policy, and international rentals often aren’t covered.
Rideshare coverage: Standard personal auto policies typically don’t cover you while driving for Uber, Lyft, or similar services. Rideshare drivers need specialized coverage or a rideshare endorsement.
Personal property in your vehicle: Auto insurance generally doesn’t cover items stolen from your car—that’s typically covered under homeowners or renters insurance.
Medical payments vs. personal injury protection: These coverages differ significantly, and understanding what’s available and required in your state is important.
Taking Action to Reduce Your Auto Insurance Costs
Avoiding these common mistakes requires periodic attention to your auto insurance rather than a set-it-and-forget-it approach. By shopping around regularly, asking about discounts, ensuring appropriate coverage levels, and keeping your insurer informed about changes in your driving habits and circumstances, you can potentially save hundreds of dollars annually while maintaining the protection you need.
Review your current policy with these ten points in mind, and consider reaching out to your insurer or shopping for quotes to ensure you’re getting the best value for your coverage needs.

Frequently Asked Questions
Insurance industry experts generally recommend comparing auto insurance quotes every 12 to 24 months, or whenever you experience a major life change such as moving, getting married, adding a new driver, or purchasing a new vehicle. Insurance rates fluctuate, and companies regularly adjust their pricing algorithms, so the best deal you found two years ago may no longer be the most competitive option today.
No, shopping for insurance quotes does not affect your current rates or your credit score. Insurance quote inquiries are considered “soft pulls” on your credit report and are not visible to other creditors or insurers. Your current insurer also has no way of knowing you’re shopping around unless you tell them.
State minimum liability coverage is generally considered insufficient for most drivers. While it meets legal requirements, minimum limits often don’t adequately cover the costs of a serious accident. If damages exceed your policy limits, you could be personally responsible for the difference. Drivers with assets to protect, such as savings, home equity, or future earnings, should consider liability limits well above state minimums.
The most commonly available auto insurance discounts include multi-policy bundling, safe driver discounts for those without recent accidents or violations, vehicle safety feature discounts, and payment-related discounts for paying in full or enrolling in automatic payments. If you work from home or drive fewer miles than average, you may also qualify for low mileage discounts. Always ask your insurer for a complete list of available discounts.
Compare the annual cost of your comprehensive and collision premiums to your vehicle’s actual cash value, which you can find through Kelley Blue Book or NADA Guides. A common guideline is that if these premiums exceed 10% of your car’s value, the coverage may not be cost-effective. However, also consider whether you could afford to repair or replace the vehicle out of pocket if you dropped this coverage.
Letting your auto insurance lapse can have multiple consequences. You may face legal penalties including fines, license suspension, and vehicle registration suspension since most states require continuous insurance coverage. When you seek new coverage, insurers will likely charge higher premiums because a coverage gap is considered a risk factor. Some states may require you to file an SR-22 certificate of financial responsibility, which adds additional costs.
