Why Is Car Insurance Mandatory?

Published: June 5, 2023

Car insurance is a critical component of responsible vehicle ownership. This requirement ensures that vehicle owners and drivers assume financial responsibility for any potential damages or injuries that may arise from car accidents.

If you’re a new driver, you might be wondering: Why is car insurance mandatory? In the United States, the landscape is as diverse as the nation itself, with various factors influencing insurance rates and regulations. Below, we delve deeper into why car insurance is universally required.

Overview of Car Insurance in the US

Each state has set its own regulations concerning minimum insurance requirements, influencing the cost of premiums. For instance, Michigan traditionally has high average premiums to its no-fault insurance law requiring unlimited personal injury protection, while states like North Dakota and Main tend to have lower average premiums. 

Despite car insurance being mandatory in most states, a significant number of drivers in the U.S. are uninsured. According to Money Geek, in 2023, 1 in 8 motorists in the US are uninsured. This brings us to the main point: why is car insurance mandatory?

Financial Protection

Accidents are unpredictable and can result in large out-of-pocket expenses. These costs can include vehicle repairs, medical bills for any injuries incurred, and possibly substantial legal fees if a lawsuit arises from the accident.

By having car insurance, you transfer these potential financial risks to the insurance company, providing yourself with a safety net against these unanticipated expenses.

Legal Requirement

In almost all states, drivers are required by law to have a minimum amount of car insurance. These requirements are primarily liability coverage that pays for bodily injuries and property damage you cause to others in an accident.

If you're caught driving without insurance, you could face penalties ranging from fines and license suspension to imprisonment, depending on your state's laws.

Protection Against Uninsured and Underinsured Motorists

Despite laws requiring insurance, some drivers still operate their vehicles uninsured. Others might carry only the bare minimum insurance, which might not be enough to cover the costs of an accident. Your own uninsured/underinsured motorist coverage can protect you in these scenarios, paying for your damages and medical bills.

Lender and Lease Requirements

If you're financing or leasing your car, the lender or leasing company will typically require you to have comprehensive collision coverage. These coverages protect their investment in the vehicle in the event of damage or a total loss.

Promotion of Responsible Behavior

Mandatory car insurance laws promote responsible behavior among drivers. With the knowledge that they have insurance coverage, drivers may feel more secure, potentially promoting safer driving habits.

Coverage for Personal Injuries

Medical payments or personal injury protection (PIP) coverage can pay for your medical bills regardless of who is at fault in an accident. In certain "no-fault" states, this type of coverage is mandatory.

Compensating Victims

Car insurance is also essential for ensuring that victims of car accidents are adequately compensated for their losses. This includes medical expenses, lost wages due to injuries, and property damage. Without insurance, the at-fault driver might be unable to cover these costs, leaving the victim with hefty expenses.

Assurance of Roadworthiness

In many cases, insurance companies require that insured vehicles be in safe working order. This requirement indirectly promotes the maintenance and roadworthiness of vehicles, contributing to overall road safety.
