Connecticut license plate laws require most vehicles to display two plates — one front, one rear — that stay clean, unobscured, and firmly attached, backed by a current registration and continuous insurance. Motorcycles and other single-plate vehicles display their plate at the rear. Getting any of this wrong is usually an infraction rather than a crime, but the fines, surcharges, and DMV penalties add up fast.
How Plates Must Be Displayed
Both plates must be mounted horizontally and fastened so they don’t swing. Every letter and number has to remain readable at all times. Nothing can be attached to the plate or to the vehicle in a way that blocks any information on the plate, and that includes tinted covers and decorative frames that overlap the characters. When your headlights are on, the rear plate must be lit well enough to read from 50 feet away.1Justia. Connecticut Code 14-18 – Display of Number Plates and Stickers
The same legibility standards apply to temporary plates. If your cover, frame, or dirt buildup hides part of the plate, an officer can cite you even when the plate itself is valid.
Registration Basics and Fees
You have to register a vehicle with the Connecticut DMV before driving it on public roads. New registrations happen at a DMV hub or branch office, or through a participating dealership. The base registration fee for a standard passenger car is $120 for a three-year period. Common add-ons include:
- $5 plate fee
- $25 title fee
- $10 administrative fee
- $15 Clean Air Act fee
- $10 lien fee, if applicable
- $40 emissions exemption fee for vehicles four years old or newer that haven’t yet passed emissions testing
- $15 greenhouse gas fee for vehicles with a certificate of origin
Those figures come from the DMV’s published fee schedule.2CT.gov. DMV Fees
Every non-commercial registration also carries a mandatory Passport to the Parks fee. As of July 1, 2025, that fee is $24 for a standard three-year registration, or $8 per year for seniors 65 and older renewing annually. It applies to new registrations, renewals, and plate transfers. In exchange, anyone riding in a Connecticut-registered vehicle parks free at all state parks and forests year-round.3CT.gov. Passport to the Parks
You’ll need a current Connecticut insurance identification card at the counter. The DMV monitors coverage on registered vehicles. If your insurance lapses for more than 14 days, the DMV mails a suspension notice and charges a $200 civil penalty before you can restore your registration privileges. If you can prove you actually had continuous coverage, the fine may be rescinded.4CT.gov. Comply with Insurance, Tax, and Registration Laws
Renewing on Time
The DMV mails renewal notices about 45 days before your registration expires, but the expiration date is your responsibility to track. You can renew online, by mail, or in person, and online is the fastest. Let the registration sit expired for more than five days and a $10 late fee kicks in.5CT.gov. Renew Your Vehicle Registration
Driving within 30 days of the expiration date is treated as a lower-level infraction for failure to renew, and it won’t affect your driver’s license. Past 30 days, you face the full penalty for operating an unregistered vehicle.6Justia. Connecticut Code 14-12 – Motor Vehicle Registration
Transferring, Canceling, and Replacing Plates
When you sell one vehicle and buy another, you can transfer existing plates rather than buying new ones. A transfer gives you a full new registration period starting from the transfer date, and the $24 Passport to the Parks fee applies just as it does to a new registration.7CT.gov. Transfer Your License Plate from One Car to Another
If you sell a vehicle without transferring the plates, move out of state, or take a car off the road, cancel the registration with the DMV. You can do this by mail with the marker plate notice form (E-159) and the registration refund request form (F-82), sent to the DMV’s Registry Record Section in Wethersfield. Connecticut does not require you to physically return the plates; you can discard them at your discretion.8CT.gov. Cancel Your Registration and Plates
Lost or stolen plates get replaced through the DMV’s Special Order Plate Unit for $45. There’s a catch that trips people up: you must wait 10 months from the date you reported the plates lost or stolen before the replacement set can be issued.9CT.gov. Replacement Plate Application In the meantime, a temporary registration may be needed to keep driving legally. Temporary plates are issued in 10-day increments; a standard passenger vehicle costs $21 per 10-day period.10CT.gov. Get a Temporary Registration
Specialty, Vanity, and Accessibility Plates
Connecticut allows vanity plates with a combination of letters and numbers you choose, on either a standard or a specialty design. You need a valid Connecticut registration first, and the DMV reserves the right to deny requests it considers inappropriate.11CT.gov. Get Special and Vanity DMV Plates
Thirteen distinctive plates honor service members, veterans, retirees, and their families. The flag-style veteran plate is available to honorably discharged veterans and active-duty members. Gold Star family plates are issued at no cost to eligible surviving relatives, and Medal of Honor recipients and former prisoners of war receive two free sets and a special registration certificate.12My Air Force Benefits.

Accessibility parking placards come in two versions. Renewable permits carry no fee; temporary permits cost $5 and cannot be renewed once they expire. Both require an application with medical certification from a licensed professional. Renewable permits can be renewed up to six months before expiration or within 60 days after.13CT.gov.

Penalties for Non-Compliance
Most plate and registration violations in Connecticut are infractions. An infraction is not a criminal offense, but the fines and court surcharges still hit hard.
Plate Display Violations
Failing to display plates properly, or having plates that are obscured, illegible, or improperly attached, carries a total penalty of $117: a $50 fine plus $67 in court fees and surcharges. The same $117 total applies whether the problem is a missing plate, a tinted cover, or any attachment blocking plate information.14State of Connecticut Judicial Branch. State of Connecticut Mail-In Violations and Infractions Schedule
Registration Violations
Operating, parking, or allowing someone else to drive an unregistered vehicle on any public road is an infraction. A Connecticut resident caught driving a vehicle they own on plates from another state faces a $250 fine, though first-time violators can have the fine suspended by showing proof of proper Connecticut registration before the fine is imposed. If your registration expired within the last 30 days, you’ll be charged the lower failure-to-renew amount instead of the full unregistered-vehicle penalty.6Justia. Connecticut Code 14-12 – Motor Vehicle Registration
Insurance Lapses
An insurance lapse triggers separate DMV consequences. If a gap exceeds 14 days, your vehicle registration and all registration privileges are suspended, which means you cannot register a new vehicle or renew an existing registration until you resolve it. Restoring registration after an insurance suspension requires a $200 civil penalty for each lapse.4CT.gov. Comply with Insurance, Tax, and Registration Laws
