A quiet but consequential shift is underway in how motorcycle crash evidence gets collected, preserved, and ultimately used in civil litigation. Beginning in 2025, the National Highway Traffic Safety Administration expanded its Crash Investigation Sampling System to systematically capture motorcycle-specific crash data for the first time in the program’s history. By 2026, that data is beginning to reach attorneys, adjusters, and courts—and the implications for settlement negotiations are profound. For injured riders and surviving families, NHTSA motorcycle crash investigation data settlement strategy is no longer theoretical. It is an actionable evidentiary tool.

What Is NHTSA’s CISS Program and Why Does It Matter to Motorcycle Riders in 2026?

The Crash Investigation Sampling System launched in 2015 as NHTSA’s primary mechanism for collecting in-depth, nationally representative crash data. Unlike police reports or insurance company reconstructions, CISS deploys trained investigators to crash scenes to document physical evidence before it disappears. The program expanded to 40 data collection sites by 2024, and added pedestrian-specific data collection that same year. The motorcycle-specific data collection module formally began in 2025, making 2026 the first full year in which attorneys can begin accessing and deploying this evidence in active cases.

What makes CISS data categorically different from other crash investigation sources is its methodology. Investigators conduct scene analysis, measure skid marks, document road surface conditions, photograph vehicle damage patterns, and code injury causation using standardized protocols. Every data point is captured under federal guidelines with no financial stake in the outcome. That independence is precisely what gives NHTSA motorcycle crash investigation data settlement applications their legal weight.

The Scale of the Motorcycle Safety Crisis Driving Federal Action

The urgency behind expanding CISS to include motorcycles is not procedural—it is statistical. According to NHTSA data released in September 2026, motorcyclist fatalities reached 6,228 in 2024, representing 16% of all traffic deaths—the highest proportion recorded in decades. That figure reflects a crisis severe enough to justify a dedicated federal data infrastructure for the first time. Early 2026 data compounds the concern further: motorcyclists were the only tracked group to see fatalities tick upward—by 1%—in Q1 2026, even as all other road user categories showed measurable improvement, according to The Crash Report published in April 2026.

The per-mile risk profile makes the aggregate numbers even more alarming. Motorcyclists are 27 times more likely to die in a crash than passenger car occupants when measured per vehicle miles traveled, and five times more likely to sustain injuries. Yet despite this disproportionate vulnerability, motorcycle accident claims have historically been undervalued and over-contested by insurers who exploit gaps in objective evidence. The introduction of federal investigative data directly addresses that gap.
