Connecticut Car Insurance Requirements
Connecticut law requires all drivers to carry minimum liability insurance plus uninsured/underinsured motorist coverage, often called 25/50/25 + UM/UIM:
- $25,000 bodily injury liability per person
- $50,000 bodily injury liability per accident
- $25,000 property damage liability per accident
- $25,000/$50,000 uninsured/underinsured motorist coverage
Connecticut is one of the few states that requires uninsured/underinsured motorist (UM/UIM) coverage by default. You can reject it in writing, but this is not recommended—UM/UIM protects you if hit by a driver without insurance or with insufficient coverage.
Understanding UM/UIM: Connecticut's mandatory UM/UIM requirement provides important protection. About 9% of Connecticut drivers are uninsured, and many more carry only minimum liability limits. UM/UIM ensures you're covered even when the at-fault driver isn't.
Most insurance experts recommend higher limits than Connecticut's minimums, such as 100/300/100 liability with matching UM/UIM, to adequately protect your assets.
Proof of Insurance in Connecticut
Connecticut drivers must carry proof of insurance at all times. Acceptable forms include:
- Insurance ID card (physical or digital)
- Insurance policy declaration page
- Electronic proof on your smartphone
Connecticut accepts digital proof of insurance. You can show a photo, PDF, or insurer app on your phone during a traffic stop or after an accident.
Penalties for driving without insurance: First offense: $100-$500 fine, license suspension, and potential vehicle impoundment. Subsequent offenses: Higher fines, longer suspensions, and SR-22 filing requirements. You'll also be personally liable for all damages if you cause an accident.
Average Car Insurance Costs in Connecticut
Connecticut drivers pay an average of $1,712 per year for full coverage car insurance, or about $143 per month. This is slightly above the national average. Minimum coverage averages around $612 per year.
Rates vary significantly by city, ZIP code, and driver profile:
City rate examples (average full coverage):
• Hartford: $1,945/year
• Bridgeport: $1,889/year
• New Haven: $1,823/year
• Stamford: $1,712/year
• Waterbury: $1,798/year
Urban areas like Hartford and Bridgeport have higher rates due to traffic density and higher theft rates.
Factors that affect your Connecticut car insurance rate include your ZIP code and city, driving record (accidents, tickets, DUIs), age and experience level, credit score (Connecticut allows credit-based pricing), vehicle make and model, annual mileage, coverage limits and deductibles, and discounts applied.
The only way to know your actual rate is to compare personalized quotes from multiple carriers.
Coverage Options Beyond the Minimum
Connecticut's minimum requirements already include UM/UIM coverage, but you may need more. Consider adding these coverages:
Higher Liability Limits: Connecticut's 25/50/25 minimum is low for serious accidents. Consider increasing to 100/300/100 or higher to protect your assets. The cost difference is often minimal, especially when bundled with higher UM/UIM limits.
Higher UM/UIM Limits: Match your UM/UIM coverage to your liability limits. If you increase liability to 100/300/100, also increase UM/UIM to 100/300. This ensures comprehensive protection whether you're at fault or the victim.
Collision Coverage: Pays for damage to your car after an accident, regardless of fault. Recommended if: Your car is worth more than your deductible (typically $500-$1,000).
Comprehensive Coverage: Covers theft, vandalism, fire, weather damage, and animal strikes. Connecticut experiences winter weather (snow, ice storms) and deer collisions. Recommended if: Your car is worth more than a few thousand dollars.
Medical Payments (MedPay): Covers medical expenses for you and your passengers, regardless of fault. Connecticut doesn't require it, but it can supplement health insurance. Common limits: $1,000-$10,000.
Rental Reimbursement: Covers rental car costs while your vehicle is being repaired after a covered claim. Typical cost: $20-$40/year.
Roadside Assistance: Covers towing, flat tire changes, lockouts, and jump-starts. Typical cost: $10-$30/year.
Understanding Connecticut's UM/UIM Requirement
Connecticut requires uninsured/underinsured motorist (UM/UIM) coverage matching your liability limits. Here's what it covers:
Uninsured Motorist (UM): Covers you if hit by a driver with no insurance. About 9% of Connecticut drivers are uninsured, so this protection is valuable.
Underinsured Motorist (UIM): Covers you if hit by a driver whose liability limits are too low to cover your damages. For example, if you have $100,000 in medical bills but the at-fault driver only has $25,000 in coverage, your UIM coverage pays the difference.
Why Connecticut requires UM/UIM: Many drivers carry only minimum liability limits (25/50/25), which are inadequate for serious accidents. UM/UIM ensures you're protected even when other drivers aren't. This is especially important in Connecticut, where medical costs and living expenses are high.
You can reject UM/UIM in writing, but this is generally not recommended unless you have comprehensive health insurance and substantial personal assets to cover potential gaps.
SR-22 Insurance in Connecticut
An SR-22 is not a type of insurance—it's a certificate your insurer files with the Connecticut DMV proving you carry liability insurance. Connecticut requires SR-22 after:
- DUI or DWI conviction
- Driving without insurance
- Multiple at-fault accidents or serious traffic violations
- License suspension or revocation
- Accumulating too many points on your license
The SR-22 filing fee is typically $15-$25, but your insurance premiums will increase significantly—often by 50-80% or more—because you're now classified as high-risk.
How long do you need SR-22 in Connecticut? Typically 3 years from the date of conviction or license reinstatement. If your policy lapses during this period, your insurer notifies the DMV and your license is suspended again.
Pro tip: Not all carriers offer SR-22 filings, and rates vary dramatically between those that do. Shop around—you could save hundreds per year even with an SR-22 requirement.
Connecticut-Specific Car Insurance Laws
Connecticut is an at-fault state: The driver who causes an accident is responsible for damages. You can file a claim with the at-fault driver's insurance or sue them directly.
Mandatory UM/UIM coverage: Connecticut requires insurers to offer UM/UIM coverage matching your liability limits. You can reject it in writing, but most drivers should keep this important protection.
Credit-based insurance scoring: Connecticut allows insurers to use credit scores when setting rates. Improving your credit can help lower your premium.
Good student discount: Connecticut insurers typically offer discounts for young drivers (under 25) who maintain good grades (usually a B average or better). This can save 10-25% on premiums.
Military deployment exemption: Connecticut offers premium relief for active-duty military personnel deployed overseas. Contact your insurer to suspend or reduce coverage during deployment.

8. Review your coverage annually. As your car ages, you may be able to drop collision and comprehensive if the vehicle is worth less than 10Ă— your deductible. Keep liability and UM/UIM coverage.
9. Take a defensive driving course. Connecticut insurers often offer discounts for completing an approved defensive driving course, especially for drivers over 55.
