New Car Insurance Requirements — Maryland

Your New Car and Your Existing Policy
You drove your new car off the lot and now you're wondering whether it's insured under your existing Maryland auto policy. Most carriers extend coverage to a newly-acquired vehicle automatically for a limited window—typically 14 to 30 days—but that window starts the moment you take possession, not the moment you call to add it. If you wait too long and file a claim before formally adding the vehicle, the carrier can deny coverage even though you've been paying premiums on your other cars.
Maryland law requires every registered vehicle to carry at least $30,000 per person and $60,000 per accident in bodily injury liability, plus $15,000 in property damage liability. Personal injury protection and uninsured motorist coverage are also mandatory. Your new car must meet these minimums before you can register it, and your carrier will not issue proof of insurance until the vehicle is formally added to your policy.

What the Grace Period Actually Covers
The grace period is not a registration extension—it's a coverage bridge. When you buy a new car, your existing policy's liability, collision, and comprehensive coverage extend to the new vehicle at the same limits you carry on your other cars. If your current policy includes collision with a $500 deductible, your new car gets that same coverage during the grace window. If you carry only liability on your existing vehicles, the new car gets only liability during the grace period.
The clock starts when you take possession, not when you drive the car home or when the title transfers. Possession means the moment you sign the purchase agreement and receive the keys. Most Maryland carriers give you 14 days; some extend it to 30. The grace period does not renew—it's a one-time window per vehicle acquisition.
After the grace period expires, any coverage on the new vehicle stops unless you have formally added it to your policy. If you're in an accident on day 31 and you never called your carrier, the claim will be denied. The carrier will continue to insure your other vehicles, but the new car sits uninsured even though you've been paying premiums.

What Happens When You Add a Vehicle Mid-Term
Adding a vehicle mid-term does not simply tack a flat amount onto your existing premium. The carrier re-rates the entire policy based on the new vehicle count, the combined exposure, and whether you qualify for a multi-car discount. If this is your second vehicle, most carriers apply a multi-car discount that lowers the per-vehicle rate on both cars. If you're adding a third or fourth vehicle, the discount typically increases. The discount applies only when every vehicle sits on the same policy and shares the same garaging address.
The premium adjustment is prorated to your renewal date. If you add a vehicle halfway through your policy term, you'll owe half of the additional annual premium immediately, and the full adjusted premium will apply at renewal. Some carriers spread the adjustment across the remaining months; others bill the prorated amount as a lump sum. The billing method varies by carrier—ask when you add the vehicle so you know what to expect on your next statement.
If the new vehicle is significantly more expensive to insure than your existing cars—because it's newer, faster, or statistically more likely to be stolen—the premium increase can be larger than the cost of insuring one additional car. A household adding a high-value SUV to a policy that currently covers two sedans will see a bigger jump than a household adding a third sedan of similar age and value.

Coverage Decisions for Your New Car
If you're financing or leasing the new vehicle, the lender will require collision and comprehensive coverage until the loan is paid off. If you own the car outright, collision and comprehensive are optional, but dropping them means you pay out of pocket to repair or replace the vehicle after an accident, theft, or weather damage. A conventional rule of thumb: if the vehicle's value is less than ten times your annual collision and comprehensive premium, consider dropping those coverages and self-insuring the risk.
Maryland requires uninsured motorist coverage on every policy, and you cannot waive it unless you do so in writing. The coverage applies to every vehicle on your policy, including the new car you just added.
Register Your New Car With the MVA
Maryland will not register your new car until you provide proof that it's insured. Once your carrier adds the vehicle to your policy and files the FR-19 certificate electronically with the MVA, you can complete registration at any MVA branch or online via the MVA's eServices portal. You'll need the title, the bill of sale, and the FR-19 confirmation from your carrier. Registration fees vary by vehicle weight and type; expect to pay a base registration fee plus titling and processing fees.
If you're replacing a vehicle, you can transfer your existing Maryland plates to the new car. If you're adding a vehicle without removing one, you'll need new plates. The MVA issues plates at the time of registration. Keep your proof-of-insurance certificate in the vehicle at all times—Maryland law requires you to show it to law enforcement on request, and driving without proof of insurance can result in a fine and points on your license even if you are insured.
How to Add Your New Car to Your Maryland Policy
Call your carrier or log into your account portal before the grace period expires. You'll need the vehicle identification number (VIN), the purchase date, the odometer reading, and proof of ownership—either the title or the bill of sale. The carrier will ask whether you're replacing an existing vehicle or adding a vehicle to the policy. If you're replacing a car you sold or traded, the new vehicle takes the old vehicle's spot and the premium adjusts based on the difference in value and risk. If you're adding a vehicle without removing one, the carrier re-rates the entire policy to reflect the additional exposure.
Most carriers issue an updated proof-of-insurance certificate immediately after you add the vehicle. Maryland requires you to carry proof of insurance in every vehicle you drive, and the Maryland Motor Vehicle Administration will not register your new car without an FR-19 certificate from your carrier showing that coverage is in place. The FR-19 is the state's standardized proof-of-insurance form—your carrier files it electronically with the MVA when you add the vehicle, and you receive a copy for your records.

How long do I have to add a new car to my Maryland insurance policy?
Most Maryland carriers give you 14 to 30 days from the date you take possession of the vehicle. The grace period starts when you sign the purchase agreement and receive the keys, not when you register the car or drive it home. After the grace period expires, coverage on the new vehicle stops unless you have formally added it to your policy.
Does my existing Maryland auto policy automatically cover a new car?
Yes, but only during the grace period—typically 14 to 30 days. Your new car is covered at the same liability, collision, and comprehensive limits you carry on your other vehicles. If you carry only liability on your existing cars, the new car gets only liability during the grace window. After the grace period expires, you must formally add the vehicle to maintain coverage.
What documents do I need to add a new car to my Maryland policy?
You need the vehicle identification number (VIN), the purchase date, the odometer reading, and proof of ownership—either the title or the bill of sale. Your carrier will use these documents to add the vehicle and issue an updated FR-19 certificate, which the MVA requires before you can register the car.
Will adding a new car increase my Maryland insurance premium?
Yes. Adding a vehicle mid-term re-rates your entire policy based on the new vehicle count and combined exposure. If this is your second vehicle, most carriers apply a multi-car discount that lowers the per-vehicle rate on both cars. The premium adjustment is prorated to your renewal date, and you'll owe the additional amount immediately or spread across remaining months depending on your carrier's billing method.
Can I register my new car in Maryland before adding it to my insurance?
No. Maryland requires proof of insurance before registration. Your carrier must add the vehicle to your policy and file an FR-19 certificate electronically with the MVA before you can complete registration. The MVA will not issue plates or registration documents until the FR-19 is on file.
What happens if I don't add my new car before the grace period expires?
Coverage on the new vehicle stops, even though you're still paying premiums on your other cars. If you're in an accident after the grace period expires and you never formally added the vehicle, the carrier will deny the claim. Your other vehicles remain insured, but the new car sits uninsured until you add it.
