QUICK ANSWER
The number of uninsured drivers is rising across the United States, with over 15 percent of motorists currently operating vehicles without coverage. This trend places insured drivers at significant financial risk for out of pocket costs related to property damage and medical bills after a no fault accident. To stay protected, motorists should consider adding uninsured and underinsured motorist coverage to their policies. These supplemental options help pay for expenses that the at fault party cannot cover, providing a vital safety net in states with high rates of uninsured drivers like Mississippi, New Mexico, and Michigan.
The National Highway Traffic Safety Administration has reported that the United States experiences millions of motor vehicle accidents every year. Driving is an inherently risky activity, with personal injury and property damage being some of the most common consequences. To reduce the financial burden that comes with these consequences, auto insurance is mandatory in most states. Despite this, millions of vehicles on the road today are uninsured, and this number is only growing.

Do You Need Collison and Comprehensive Coverage?
Fausto Bucheli Jr, licensed insurance broker and owner of CheapInsurance.com, recommends: “Collision and comprehensive coverage should protect your financial stability, not drain it. If your car is older and paid off, adjusting or removing these coverages can reduce your car insurance costs by hundreds of dollars per year without increasing your real financial risk.”
| Scenario | Recommendation |
|---|---|
| Car is financed or leased | Yes – Required by lender |
| Car worth >$4,000 and you can’t afford to replace it | Yes – Strongly recommended |
| Car worth <$3,000 and you have emergency savings | Optional – Consider dropping |
| Older vehicle paid off with low value | Optional – Liability only may be enough |
Why do people drive uninsured?
There are legal, social, and economic reasons why some drivers forego having auto insurance. Some people are not required to have insurance, some face barriers to getting it, and some cannot afford it.
New Hampshire is the only U.S. state where car insurance is not mandatory for drivers. In states where it is required, the dollar amount of bodily injury liability per person, per accident, and property damage liability can vary.
Socially, some individuals face barriers to getting car insurance and may not even be able to obtain it. For example, those with a poor driving history (multiple collisions or DUI convictions) or those with a record of insurance fraud may find it challenging.
Financially, many people struggle to afford car insurance and may choose to go without it as a result. In fact, a 2024 industry report from Deloitte reported that up to 45% of young Americans have considered going without insurance because of rising costs. Due to how insurance premium pools work, the cost will only go up as more people skip coverage. Many of the most expensive states for car insurance also experience the highest number of uninsured drivers.
Issues with enforcement
Enforcement can vary across jurisdictions. In some states, harsher punishments apply, such as hefty fines, jail time, and license suspension. In many others, such as Connecticut, the punishments are negligible and include “no action,” “verbal warning,” “written warning,” a ticket, or a misdemeanor.
The risks that insured drivers face
Uninsured drivers pose a substantial risk to insured drivers on the road, mainly financial. If a driver experiences a no-fault accident with a driver who does not have insurance, their damages may have to be covered by their own insurance company or out of pocket. While drivers can go after an uninsured driver through a lawsuit, the potential legal costs can outweigh the settlement.
Some of the key financial risks that drivers face from uninsured motorists include the following.
- Property damage costs: If a person’s vehicle is damaged in an accident by a driver without insurance, they will not be able to file a claim with the insurer of the driver responsible for the accident. This often means that they must go through their own insurance company and file a claim.
- Bodily injury costs: Personal injury is a real possibility for many accidents. A person may be forced to pay their own medical bills if hit by an uninsured driver. Even in the case of a lawsuit, it may take six months to a year to get a payout.
- Higher insurance premiums: If a person has to use their own comprehensive insurance to file a property damage or bodily injury claim, they may face higher premiums in the future, even if they were not at fault.
Avoiding risk: Insurance strategies to consider
Fortunately, there are ways to reduce the financial risk one faces from uninsured drivers on the road. Many auto insurance companies offer a supplemental add-on called uninsured/underinsured motorist coverage.
Uninsured motorist (UM) coverage protects drivers against any personal injury costs associated with the accident. Underinsured motorist (UIM) coverage pays the difference between how much the personal injury costs were and how much the at-fault party’s insurance was willing to cover.
Most of the time, optional UM/UIM insurance only covers personal injury. Uninsured motorist property damage (UMPD) is another add-on that an insurer can provide. This will cover any costs associated with the repair of a damaged vehicle.
How to expand coverage to protect against uninsured drivers
The simplest way for a person to get UM/UIM coverage is to contact their auto insurance company; however, the availability can depend on the state. In around 20 jurisdictions, it’s mandatory to have UM coverage, whereas in others, it’s just a requirement that it’s offered to the customer. UIM coverage is less common and is only required in a small selection of states.
While adding this type of insurance doesn’t help curb the problem of the growing number of uninsured drivers, it does reduce the risk for those who have coverage.
Staying protected against uninsured drivers
The increasing occurrence of uninsured driving across the country highlights the importance of understanding the risks and available protections. Until the social and economic factors driving this trend change, the number of uninsured drivers is unlikely to decrease.
Supplemental uninsured motorist insurance can mitigate the financial risks associated with sharing the road with drivers who do not have coverage, offering financial security in the event of a no-fault accident or personal injury.

Frequently Asked Questions About Uninsured Drivers
What is an uninsured driver?
An uninsured driver is someone operating a vehicle without the legally required auto insurance. If they cause a crash, they may not have coverage to pay for your medical bills or vehicle repairs, which can leave you relying on your own policy or paying out of pocket.
How can I protect myself if I’m hit by an uninsured driver?
The most direct protection is uninsured/underinsured motorist coverage (UM/UIM), which can help pay for injuries when the at-fault driver has no coverage or not enough. Depending on your state and insurer, uninsured motorist property damage (UMPD) may help with vehicle repairs, and carrying collision coverage can also cover damage to your car after a hit-and-run or uninsured-driver crash (minus your deductible).
Are uninsured drivers increasing, and which states have the highest rates?
Yes. Recent data shows uninsured driving is rising nationwide. Rates vary by state, with some of the highest percentages reported in Mississippi, New Mexico, and Michigan, while states like Maine, Utah, and Idaho have some of the lowest uninsured-driver rates.
