Layton Truck Accident: Utah's Statute of Limitations & Preservation Steps

Utah Code § 78B-2-307 sets the personal injury statute of limitations at four years from the date of the accident. This is not a soft deadline — judges will dismiss your case if filed after this date, regardless of the merits of your claim or the severity of your injuries. [Research from NHTSA](https://www.nhtsa.gov/) on commercial vehicle crash outcomes underscores why timing matters: truck accident injuries are often catastrophic, and medical treatment needs are immediate.

For truck accidents specifically, the four-year clock begins on the day of the crash, not when you knew or should have known about your injuries. A driver hit by an 18-wheeler on I-15 in March 2022 has until March 2026 to file suit. If settlement negotiations are ongoing or you're still in medical treatment on March 26, 2026, it doesn't matter — the lawsuit must be filed by midnight on that fourth anniversary.

Under Utah's discovery rule, which applies in limited circumstances, the clock might start from when you discovered (or should have discovered) the injury. However, in truck accidents — where the injury is immediate and obvious — courts interpret this rule narrowly. Count on the four-year window from impact, not from diagnosis.

The statute of limitations clock starts the moment the collision occurs, even if you don't seek medical attention immediately. Some truck accident victims don't experience the full impact of their injuries for days or weeks (spinal injuries, traumatic brain injuries, internal bleeding). That lag makes no difference to the SOL clock — it started the day of the crash.

For wrongful death claims arising from a truck accident fatality, the clock starts on the date of death, not the date of discovery. If a driver dies on April 15 from complications of injuries sustained in a March 2 crash, the wrongful death claim is measured from April 15.

In rare cases, if the defendant intentionally concealed the accident (e.g., a commercial carrier disposed of crash evidence and actively misrepresented the incident), Utah courts may apply the discovery rule to delay the start date. But these situations are exceptions. The default rule: injury date equals SOL start date.

Utah recognizes limited exceptions to the four-year rule:

Minors: If the injured party is under 18 at the time of the crash, the statute of limitations doesn't run until they turn 18, plus four years. A 10-year-old hit by a truck in 2025 has until age 22 plus four additional years (age 26) to file.

Legally Incapacitated Adults: If the plaintiff is adjudged legally incapacitated (unable to manage their affairs) at the time of the accident, the SOL period is tolled until they regain capacity or a guardian is appointed. This is narrowly defined and rarely invoked in truck accident cases.

Government Defendants: If a government agency (county, state, or local authority) is responsible for the accident or liable for negligent road maintenance, different notice requirements apply. You must file a notice of claim within 180 days of the incident, separate from the four-year lawsuit deadline.

Absence from the State: If the defendant leaves Utah before the SOL expires, time spent outside the state does not count toward the deadline, but this exception is difficult to prove and rarely applies in commercial trucking cases where the carrier is incorporated in Utah or operates a permanent facility here.

These exceptions are narrow and fact-specific. The baseline: four years, measured from the date of the crash.

If you file a lawsuit after the four-year SOL expires, the defendant's attorney will file a motion to dismiss based on the statute of limitations. The judge will grant it, and your case is over before discovery, before trial, before anything. Utah courts do not have discretion to hear cases filed after the SOL period closes.

This is why the final month before expiration is critical. Even if settlement negotiations are ongoing, even if you're waiting for a medical report, even if your attorney is working on a demand letter — the lawsuit must be filed by the deadline. Filing protects your claim; settlement can happen afterward.

Once dismissed on statute of limitations grounds, you cannot re-file. Your only recourse is to prove one of the narrow exceptions above — that the defendant concealed the accident, that you were a minor, or that the defendant was a government agency — and even then, courts impose high burdens of proof.

For trucking company defendants, which are sophisticated repeat litigants, they rely on the SOL as a defense when plaintiffs delay. Having evidence preserved (ELD data, driver logs, crash photos) matters little if the case is dismissed on procedural grounds before it reaches trial.

Act immediately after a truck crash in Layton or Davis County. The following steps protect your legal position:

1. File a preservation letter with the motor carrier. Within days of the crash, your attorney should send a formal preservation letter to the trucking company, requiring them to preserve all evidence: ELD data, driver qualification files, maintenance records, dispatch communications, telematics, and any dashcam footage. Federal regulations require carriers to maintain certain records, but a preservation letter creates an independent legal duty and prevents spoliation claims later.

1. Obtain the crash report from Layton Police Department or the Utah Highway Patrol. The official incident report is part of the public record and contains statements, scene photos, and the investigating officer's observations. Request it immediately; police records are sometimes purged after a set period.

1. Collect medical records and treatment documentation. Begin treatment immediately and keep detailed records of every appointment, test, and diagnosis. This creates a contemporaneous record of injury severity and treatment history.

1. Document the scene and vehicles if safe. Take photos of damage patterns, road conditions, sight lines, and the relative positions of vehicles. Assign a witness or have a family member help if you're injured.

1. Request the defendant's DOT safety record and CSA scores. The [FMCSA's Safety Management System](https://www.fmcsa.dot.gov/) is publicly accessible. The motor carrier's Compliance, Safety & Accountability (CSA) score, unsafe driving violations, and hours-of-service violations are documented there and often establish the carrier's negligent pattern.

1. Consult a truck accident attorney in Davis County well before the four-year deadline. An attorney familiar with commercial motor vehicle litigation will immediately issue preservation demands, analyze the discovery scope, and build a timeline that respects the SOL window. Do not wait until year three — do it within weeks of the crash.
