Connecticut residents must register their vehicles in-state within 60 days of establishing residency. Operating a New York-registered vehicle in Connecticut beyond this period can result in: daily fines (amount varies by vehicle type and duration), driver's license suspension, and vehicle impoundment. The driver may also face liability for damages in any accident. To comply, visit a CT DMV office with the vehicle title, CT driver's license, proof of insurance, and proof of residency. A new CT registration and plates will be issued, with an annual fee. Prompt re-registration avoids escalating penalties and legal exposure.
