New Hampshire doesn't have a lot of interstate, but what it has is busy: I-93 up from the Massachusetts line through Manchester and Concord, and I-95 on that short seacoast stretch into Maine.

The truck accident statute of limitations in New Hampshire appears to be 3 years from the date of the crash (RSA § 508:4). Wrongful death generally runs 3 years from the date of death. If a government vehicle or entity was involved, formal written notice is generally required first, on its own clock: 180 days. The evidence clock is shorter than all of them.

How current these numbers are

A licensed attorney checked these New Hampshire figures against the cited statutes on 2026-09-20. Statutes still change (Florida cut its injury period in half in 2023; Louisiana doubled its own in 2024), so confirm with a New Hampshire lawyer before you rely on them.

Life next to big rigs on I-93

Southern New Hampshire is basically a commuter extension of Boston, and I-93 near Salem and Manchester stays crowded. Trucks share it with daily traffic and a lot of lane changes. Head north and the road climbs into the White Mountains, where Franconia Notch narrows and grades and curves get serious. Winter nor'easters and freezing rain make every hill a gamble, and black ice on Route 16 and Route 101 catches drivers who think the plows have been through. Fall foliage season brings slow-moving tourists who stop without warning for the view, and that's a rear-end risk for any loaded rig coming down a grade.

New Hampshire's freight is largely regional distribution serving northern New England, plus port-adjacent traffic through Portsmouth. I-93 through the notches and Route 16 to the North Country carry heavy trucks on grades and in winter conditions. Crashes pile up on I-93 (Salem–Manchester–Franconia Notch), I-95 through the seacoast, I-89 toward Vermont, Route 101 and Route 16 and The Everett Turnpike.

How the clock plays out: a crash on Route 16

Say you're a local driver delivering building supplies up Route 16 in February, and a tractor-trailer coming the other way loses traction on a hill and crosses the line. You're hurt and your company's already asking when you'll be back. Meanwhile, the other carrier's adjuster is calling you, friendly, asking for a recorded statement. It's easy to let the weeks go by while you heal. That time is when the other side builds its version.

What makes New Hampshire different

New Hampshire's three-year period is standard, but claims against the State run through a separate statutory scheme with its own damages cap, and a claim against a town requires written notice within 180 days. New Hampshire's discovery provision is written directly into RSA 508:4, which matters where an injury did not present immediately.

If a government vehicle was involved in New Hampshire

Shortest government notice window found for New Hampshire: 180 days (RSA § 507-B:7). It comes due long before the ordinary deadline, it's a precondition to suing, and missing it usually bars the claim entirely. Claims against the State run through RSA chapter 541-B with its own procedure and damages cap. Written notice to the municipality within 180 days of the incident.

Public fleets you could realistically be hit by here: NHDOT plow and maintenance trucks, municipal public works fleets, county equipment, and school administrative unit buses. Not sure the vehicle was one of these? Work to the shorter deadline until someone confirms otherwise.

If the injured person was a minor

Tolled to age 18 in New Hampshire under RSA § 508:8. The clock generally doesn't start until the injured person turns 18. That pause covers the court deadline, not the evidence: a carrier may destroy a driver's logs six months after the crash no matter the injured person's age, and in many states a government notice deadline isn't tolled for a child either.

When the New Hampshire clock starts

Applies. RSA § 508:4 contains an express discovery provision.

3. Did anyone die in the crash?

A wrongful death claim runs on a separate clock, and in most states it is measured differently.

4. Was a government vehicle or entity involved?

A city or county truck, a state DOT vehicle, a transit bus, a school district bus, a USPS vehicle, or a claim about how the road itself was built or maintained.

5. Was the injured person under 18 at the time?

In most states the clock is paused for a child — but the evidence clock is not, and in many states a government notice deadline is not either.

The evidence clock runs faster than 3 years

  • Dashcam and telematics video: often 30 days or less (No federal retention requirement — vendor and carrier policy only).
  • ECM / black box data: overwritten as the tractor runs; often lost on repair or resale.
  • Driver logs: six months (49 CFR § 395.8(k)(1)).
  • Maintenance records: one year while the vehicle is in the carrier's control (49 CFR § 396.3(c)).
  • Annual inspection report: 14 months (49 CFR § 396.21(b)(1)).

Until a written preservation letter reaches the carrier, destroying records at the end of a retention period is routine and lawful. The FMCSA regulations and evidence guide explains each record.

Local moves that protect a New Hampshire claim

  • On I-93, I-95 and the turnpikes, the New Hampshire State Police usually handle the crash. In towns, it may be local police, so confirm who wrote the report.
  • Toll-road gantries and weigh stations on I-93 and I-95 may have camera or transaction records that help place the truck. Ask early.
  • If ice was involved, note when you last saw a plow or sand truck. Road treatment records can show what the conditions really were.

Crashed near the New Hampshire line?

A crash a few miles over a border can fall under a different deadline. If you're not sure which state you were in, check both.

Next steps

  1. Get a preservation letter to the carrier. It's the most time-critical step.
  2. Confirm whether a government entity was involved. If so, your 3 years deadline may give way to 180 days.
  3. Don't give a recorded statement to the trucking company's insurer.
  4. Get the New Hampshire crash report; it names the carrier, DOT number and insurer.
  5. Have a lawyer licensed in New Hampshire confirm these dates against the current statute.
