Hurt in a crash with a commercial truck in Oregon? Truck claims can involve the driver, the carrier, and their insurers, and two state rules shape every claim: the filing deadline and how fault is shared.

Oregon's two-year statute of limitations under ORS 12.110(1) applies to all personal injury claims arising from truck accidents. But the real deadline pressure comes from evidence destruction. Federal regulations under 49 CFR Part 395 require carriers to maintain electronic logging device (ELD) records for only six months. Driver qualification files under 49 CFR Part 391 — drug test results, medical certificates, training records — can be purged according to the carrier's retention policy once the minimum federal period expires. An attorney who waits even six months to send a spoliation letter may find that the hours-of-service data proving the trucker was over their 11-hour driving limit or 14-hour on-duty window has already been overwritten.
Oregon adopts the full Federal Motor Carrier Safety Regulations for intrastate carriers through OAR 740-100-0010, with ODOT substituted for FMCSA wherever the federal rules cross-reference the federal agency. This means Oregon State Police and ODOT's Commerce and Compliance Division enforce the same hours-of-service rules, drug testing requirements, vehicle maintenance standards, and driver qualification standards that apply to interstate carriers. When a truck crash occurs on I-5 between Portland and Salem or on I-84 through the Columbia River Gorge, the attorney must pull both the federal FMCSA carrier safety record (via SAFER) and Oregon's state-level inspection and compliance history through ODOT.
Oregon's weight regime under ORS 818.010 is formula-based on tire ratings and axle group configuration — not a simple flat cap like many states. The tire-rating formula uses manufacturer sidewall ratings multiplied by the sum of tire widths in inches. Single-wheel maximum is 10,000 lbs; single axle 20,000 lbs; tandem 34,000 lbs. Overweight violations are a per se regulatory breach and can establish negligence when an overloaded truck's stopping distance contributed to the crash. ODOT weigh station data, inspection reports, and the carrier's load manifests are all discoverable and should be subpoenaed before they age out of retention windows.
Oregon's modified comparative fault rule under ORS 31.600 applies the 51% bar — if the injured party's fault is greater than the combined fault of all defendants, recovery is zero. In truck cases, insurers often argue that the passenger vehicle driver was following too closely, failed to stay out of the truck's blind spot, or made an unsafe lane change. Each of these arguments is designed to push fault past the 51% threshold. Trucking companies carry federal minimum insurance of $750,000 under 49 CFR § 387.9 (and often $1M+ for hazmat), so the stakes are high and defense counsel is aggressive. If a government entity was involved — an ODOT vehicle, a state highway work zone — the Oregon Tort Claims Act (ORS 30.275) imposes a 180-day written notice requirement that can extinguish the government claim before the two-year SOL even matters.
Legal Information Notice
The legal information on this page is for general educational purposes only and is not legal advice. Laws change, and every case is different. Always consult with a licensed attorney in your state to verify the current law and how it applies to your specific situation.
Oregon adopts the Federal Motor Carrier Safety Regulations (49 CFR Parts 390-399) for intrastate carriers through OAR 740-100-0010, with ODOT substituted for FMCSA. This includes hours-of-service rules under 49 CFR Part 395 (11-hour driving limit, 14-hour on-duty window, mandatory ELD), driver qualification standards under 49 CFR Part 391 (drug testing, medical certification), vehicle maintenance under Part 396, and minimum insurance under 49 CFR § 387.9 ($750,000 for general freight, higher for hazmat). Both federal FMCSA records and Oregon state-level ODOT inspection history are discoverable.
Oregon follows modified comparative fault under ORS 31.600 with a 51% bar. You recover only if your fault is not greater than the combined fault of all defendants. At 50% you recover proportionally; at 51% you recover nothing. Trucking defense attorneys are aggressive about pushing the car driver's fault past this threshold — arguing blind-spot violations, following distance, or unsafe lane changes. Every piece of evidence that documents the trucker's fault (ELD data, inspection reports, dashcam footage) is critical to keeping your share below 51%.
Two years from the date of the crash under ORS 12.110(1). But evidence deadlines are far shorter — ELD records under 49 CFR Part 395 must be retained for only six months, and driver qualification files under 49 CFR Part 391 can be purged once federal minimums expire. If a government vehicle or ODOT work zone was involved, the Oregon Tort Claims Act (ORS 30.275) requires written notice within 180 days. An attorney should send a spoliation preservation letter to the carrier within days of the crash.
Oregon's weight regime under ORS 818.010 is formula-based on tire ratings and axle group configuration. Single-wheel maximum is 10,000 lbs; single axle 20,000 lbs; tandem 34,000 lbs. The formula uses manufacturer tire sidewall ratings multiplied by tire widths in inches. An overweight truck has longer stopping distances, greater kinetic energy on impact, and increased tire blowout risk. Overweight violations are a per se regulatory breach that can establish negligence. ODOT weigh station data, the carrier's load manifests, and bill-of-lading records are all discoverable.
I-5 — the West Coast freight spine running from California to Washington through Portland, Salem, and Eugene — and I-84 through the Columbia River Gorge carry the bulk of Oregon's commercial truck volume. The I-5/I-84 interchange in Portland is one of the most congested freight corridors on the West Coast. ODOT's Commerce and Compliance Division and Oregon State Police conduct enforcement on these corridors. After a crash, ODOT traffic-camera footage from the TransPort system, weigh station records, and state inspection reports are all potentially relevant evidence.
