If you were hit from behind in Connecticut, knowing the CT rear-end collision lawsuit statute of limitations isn’t just legal detail it’s the deadline that decides whether you can file a claim at all. Miss it, and the court will almost certainly dismiss your case, no matter how clear the other driver’s fault or how serious your injuries. This rule applies the same way whether you’re dealing with whiplash, back pain that shows up days later, or vehicle damage you didn’t notice right away.

What is the CT rear-end collision lawsuit statute of limitations?

In Connecticut, the general time limit to file a personal injury or property damage lawsuit after a rear-end crash is two years from the date of the accident. That means if your crash happened on June 15, 2023, you must file your complaint in Superior Court by June 15, 2025 or risk losing your right to sue entirely. This two-year window comes from Connecticut General Statutes § 52-577 for personal injury and § 52-577a for property damage claims.

When does the clock start ticking?

For most rear-end collisions, the two-year clock starts on the day the crash happens not when you hire a lawyer, not when your medical treatment ends, and not when you decide to pursue a claim. But there are exceptions. If an injury wasn’t obvious right away like a herniated disc that only becomes painful weeks later the “discovery rule” may apply. In those cases, the clock might start when you reasonably should have known about the injury, not the crash date. You can read more about how this works in our guide on proving delayed-onset injuries after a Connecticut auto accident.

What counts as “filing” under the statute?

Filing means delivering your formal complaint to the court clerk not sending a demand letter to the insurance company, not scheduling a consultation with a lawyer, and not even mailing paperwork to the courthouse. The court must stamp and accept your documents by the deadline. If the last day falls on a weekend or holiday, the deadline moves to the next business day but don’t rely on that. Courts do not extend deadlines for mail delays, filing system errors, or missed appointments.

Common mistakes people make

  • Waiting until symptoms get worse: Some people hold off because they feel “okay” at first, then realize months later they need surgery or long-term care. By then, it may be too late to file.
  • Assuming insurance negotiations reset the clock: Talking to an adjuster or submitting bills doesn’t pause or extend the two-year deadline.
  • Mixing up the deadline with other timelines: The two-year limit is different from the time you have to report the crash to police (within 24 hours if there’s injury or $1,000+ damage) or to notify your own insurer (which varies by policy).

What if the other driver is uninsured or underinsured?

The two-year deadline still applies even if you’re making a claim under your own uninsured/underinsured motorist (UM/UIM) coverage. Those claims are treated like lawsuits against the at-fault driver for timing purposes. You’ll need to follow the same filing rules and procedures. For details on how UM/UIM claims fit into the timeline, see our page on how long after a car accident you can sue in Connecticut.

Do you need a lawyer before the deadline?

You don’t legally need one but trying to file and litigate a rear-end collision case on your own, especially close to the deadline, carries real risk. Mistakes in paperwork, service, or procedural rules can get your case thrown out even if it’s filed on time. Most experienced Connecticut auto injury lawyers recommend starting the process at least 60–90 days before the deadline. You can see a realistic breakdown of what that looks like in our timeline for hiring a lawyer after a rear-end crash in Connecticut.

What about delayed injury claims?

If your neck pain, headaches, or dizziness didn’t appear until days or weeks after the crash, you’re not automatically barred but you do need to act quickly once symptoms begin. Delayed injury claims require documentation linking the symptoms to the crash, not just time passing. That often means getting evaluated soon after symptoms start and keeping records of every visit. Our guide on the process for a delayed injury claim in Connecticut walks through how to build that link properly.

Connecticut’s two-year deadline is strict but not arbitrary it balances fairness to injured people with the need for reliable evidence and witness recollection. To check your specific situation, review the official text of CGS § 52-577, and consider speaking with a lawyer who handles rear-end collision cases in the state.

Next step: Write down your crash date. Subtract two years. Then, schedule a free consultation with a Connecticut auto injury lawyer ideally no later than 90 days before that deadline. Even if you’re unsure about suing, a short call helps confirm whether your claim is still viable and what evidence you’ll need to move forward.
